The following installation procedures are available for NMS5. • Mounting without guide system. • Mounting with stilling well • Mounting with guide wire 4.1 Application Drawing for Tank Mounting with stilling well or guide wire is required for the following applications: • Floating Roof Tank • Covered Floating Roof Tank • Tank with Strong Agitator or Heavy Turbulence Mounting without any guide system covers all cases that are not listed above. Refer to Figure 14 of applications (with and without mounting stilling well, with mounting guide wire) Figure. 14: Application for Each Tank Floating Roof Tank Fixed Roof Tank Without Stilling Well Fixed Roof Tank With Stilling Well Covered Floating Roof Tank Spherical or Bullet Tank With Guide Wire Fixed Roof Tank Spherical or Bullet Tank Floating Roof Tank ����������������������������������������������� Covered Floating Roof Tank 4 Mounting of NMS5

NMS5 is mounted on a nozzle of the tank roof without any guide system (Refer to Figure. 14: Application for Each Tank). The mounting preparations require the observance of some recommendations for setting the noz- zle and the minimum measuring level. Figure. 15: Mounting without Guide System 4.3 Mounting with Stilling Well Stilling Well Diameter The stiling well diameter that is required to protect the measuring wire without disturbing its operation varies depending on the tank height. The stiling well could either be constant diameter, or thinner at its upper part and thicker at its lower part. The figure 16 shows two examples of the latter case, namely an asymmetric pipe and a concentric pipe. Figure. 16: Mounting with Stilling Well, Asymmetric Pipe, and Connection Pipe Displacer NMS5 d D1 Valve Asymmetric Pipe Concentric Pipe Displacer Maintenace Chamber NMS5 Asymmetric Pipe (Side View) Concentric Pipe (Front View) NMS5 4 Mounting of NMS5

NMS5 must be mounted on the asymmetric pipe in the direction shown on Figure 16. To calculate the required pipe diameters, the formula below should be used. The variables and constants have the following meanings. D1 Inner diameter of the upper part of the pipe D2 Inner diameter of the lower part of the pipe L Length of the pipe (from the flange of NMS5 to bottom of the stilling well) meters v Deviation of the pipe from the vertical per length (mm/m) d Diameter of the displacer e Lateral shift of the displacer per length due to the groove of the wire drum • Upper Diameter of Stilling Well D1 > d + 10 mm D1 should be 3" or more. • Lower Diameter of Stilling Well - Asymmetric Pipe D2 > d+ eL + 2vL+ 10mm - Concentric Pipe D2 > d + 2eL + 2vL + 10mm Recommendations for Mounting Stilling Well Note! Follow the recommendations for mounting NMS5 with stilling well: • Keep the pipe connection welds smooth. • While drilling holes into the pipe, keep the interior surface of the holes clear of metal chips and burrs. • Coat or paint the interior surface of the pipe to avoid rust. • Keep the pipe as perfectly vertical as possible. Check this by a plumb. • Install the asymmetric pipe under the valve and fit the centers of the NMS5 and the valve. • Set the center of the lower part of the asymmetric pipe to the direction of the displacer motion. • Observe recommendations as per API MPMS chapter 3.1B. • Confirm grounding between NMS NMS5 and tank nozzle.

It is also possible to guide the displacer by a guide wire to prevent lateral motion. Guide Wire Installation Procedure 1. Secure the guide wire [4] to the wire hook. 2. Secure the springs [3] to the reducer plate [2] (see Figure 17). 3. Fix NMS5 [1] temporarily so that springs are located at the outside the reducer plate. 4. Perform weight calibration. 5. Fix NMS5 to the reducer plate. 6. Put displacer ring [7] through guide wire and set the displacer [5] so that marking ring [6] is located on the reference position. This completes the guide wire installation procedure.

Figure. 18: Weight Calibration for NMS with Guide Wire Weight Calibration Procedure 1. Fix NMS5 temporarily so that NMS5 is located at the outside the reducer plate to perform weight calibration. 2. Replace the measuring wire to an appropriate length. • During standard weight calibration, the displacer moves up until it touches the mechanical stop in the housing. • After weight calibration is finished, the displacer stops 70mm (the value set in the matrix (configurable, GVH378)) below the mechanical stop. This is the Reference Position. 3. During this special weight calibration, the guide rings of the displacer touches the bottom face of the flange. 4. The displacer goes down 70mm and stops. NMS5 remembers the distance of 70mm as Reference Position, and weight table calibration resumes. 5. When weight calibration is complete, return NMS5 back to its original mounting position on the tank nozzle. This completes the weight calibration procedure. 70mm Reference Position 4 Mounting of NMS5

4.5.1 Flange A nozzle and a flange should be prepared prior to mounting NMS5 on the tank. The flange size and the rating of NMS5 vary depending on the customer’s specifications. Note! • Check the flange size of NMS5. • Mount the flange on the top of the tank. The deviation of the flange from the horizontal plane should not exceed +/- 1 degree. • When mounting NMS5 on a long nozzle, ensure that the displacer does not touch the inner side of the noz- zle when the nozzle is in the vertical position. Figure. 23: Allowable Inclination of Mounting Flange Note! When NMS5 is installed without a guide system, follow the recommendations below: • Set the mounting nozzle in the sector between 45 and 90 deg (or -45 and -90 deg.) apart from the inlet pipe of the tank. This prevents heavy swing of the displacer caused by wave or turbulence of the inlet liquid. • Set the mounting nozzle at 500mm or more away from the tank wall. Ensure that the measurement is not influenced by changes of the ambient temperature. • Set the minimum measuring level at 500mm or more above the top of the inlet pipe. This protects the displacer from direct flow of the inlet liquid. • If the stilling well can not be mounted in the tank due to the shape or condition of a tank, attaching a guide system is recommended. Consult E+H services for further information. Figure. 24: Recommended Setting of Mounting Nozzle and Minimum Measuring Level Caution! • Before pouring liquid into the tank, confirm that liquid flowing through the inlet of the pipe does not touch the displacer directly. • When discharging liquid of the tank, ensure that the displacer does not get caught in the liquid current and sucked into the outlet pipe.

using a stilling well or guide wire is recommended. This releases the electrostatic charge on liquid surface. (refer to "1.5 Electrostatic Charge" details on a stiling time for a volume of a charged object). 4.7 Installation for Wire Drum and Displacer When NMS5 is delivered, there are 2 ways of packing procedures depending on mounting methods of a dis- placer. 1. For All-in-one method, the displacer is mounted on the measuring wire of NMS5. Follow the instructions to remove the packing attached to NMS5. 2. Displacer shipped separately. It is necessary to install the displacer in the measuring wire inside NMS5. Follow the instructions below. 4.7.1 All-in-one As NMS5 is protected by some packaging materials, remove them as follows prior to mounting NMS5 (refer to Figure 25: Removing Procedure for All-in-one).

6.1.1 Display and Operating Elements Display During normal operation, NMS5 has an illuminated LCD that shows the level, the temperature, and the status of the device at "HOME" position. For the display of the other data and the programming of the parameters for operation, NMS5 uses a convenient programming matrix. Operating Elements NMS5 is operated by three visual operating elements, namely the keys "E", "+", and "-" . They are actuated when the appropriate field on the protective glass of the front is touched with the finger ("touch control"). The corresponding transmitting and receiving diodes are not affected by external influences, e.g. direct sunlight. The software and hardware installed in NMS5 rule out any malfunction that may be caused in this way. Even in explosive hazardous areas, the explosion-proof housing of the touch control ensures a safe access to the data. Figure. 46: Display 6.1.2 Functions of Operating Elements The programming matrix consists of matrix groups, namely one "static" matrix and additional "dynamic" matri- ces. They are described in detail in Section "13 Matrix". The individual matrix groups, function groups, and functions within the programming matrix can be selected by alternately touching the operating elements.

The section specifies the formula used by NMS5 to calculate levels and densities. Figure. 56: Calculation of Levels and Densities Surface and Interface Levels While the measured surface or interface level is constant, the displacer rests at the balancing position. The ten- sion on the measuring wire is proportional to the displacer weight diminished by the buoyancy forces in both layers: A rise or fall of the level will increase or decrease the submerged volume. If this change exceeds the volume tolerance set at matrix position GVH=345 "VOLUME TOLERANCE", then the corresponding change will actuate the motor of the NMS5 till the balancing condition is fulfilled again. Tank Bottom Level For bottom level measurement, the balancing condition is defined as Level Formula Liquid Level T = W - Vвρu Upper Surface T = W - Vвρm - (V - Vв) ρu Middle Surface T = W - Vвρb - (V - Vв) ρm Measuring Wire Tension T Gas Density Negligible Measured Displacer Weight W Upper Liquid Density �� Measured Displacer Weight Wu Middle Liquid Density �� Measured Displacer Weight Wm Bottom Liquid Density �� Measured Displacer Weight Wb Balance Volume VB Displacer Volume V 6 Operation

• Upper density (Pu) and Density profile • Middle density (Pm) • Bottom density (Pb) Draft The draft varies depending on the shape of the displacer. For cylindrical shape, the draft is where the variables and constants have the following meanings. Figure. 57: Variables and Constants for Displacer The surface or interface level should be within the cylindrical part of the displacer and approximately in the middle of its total height. ρu = V W - Wu ρm = V Wu - Wm ρu + ρb = V Wm - Wb ρm + D = (V2 - V1) / A x 10 + h = (V1 - V2 - V3) / A x 10 + h + h1 V1 V2 h A Displacer Balance Volume (69cm3) Displacer Lower Hemisphere Volume Height of Lower Cone Cross-section of Displacer V1 V2 h A Balance Volume (69 cm3) Volume of Lower Cone (24.46 cm3) Displacer Bottom Stub Height (20 mm) Cross-section of Displacer (20.26 cm2) For example: standard displacer Ø50.8 mmCylindrical shape D = (69 - 24.46 - 0.12) / 20.26 x 10 + 20 + 3 = 44.92 V3 Displacer Bottom Stub Volume V3 Volume of End of Cone (0.12 cm3) h Height of End of Cone 1 1 d h V2 D h1 V3 Liquid Level or Interface 6 Operation

some settings may not be required. Set Access code 51 at GVH039 before applying the initial settings. 7.1.1 System Calendar/Clock (GVH193 to 197) Calendar/Clock values are set at factory (Japan Standard Time) prior to delivery. Change the data to reflect local time. 7.1.2 Density Values (GVH005 to 007) Caution! Always set GVH=005 Upper Density for actual density data, in LPG and any application where the actual den- sity is 0.7000 g/ml or less. failure to set this data may result in level gauge malfunction. Density values for 3 liquid phases are set to 1.000 g/ml prior to delivery. Change the data to reflect actual den- sity values. For tanks with only one liquid phase, set Upper Density. For tanks with 2 or 3 clear phases, set Middle and Bottom densities too. Note: minimum difference between phase settings should be at least 0.100 g/ml. *GVH005£GVH006£GVH007 Example: • GVH005 Upper Density: 0.758 • GVH006 Middle Density: 0.880 • GVH007 Density Bottom: 1.000 7.1.3 Tank Height (GVH140) Tank height value is set to default value at factory prior to delivery. Tank height is the reference height, usually a gauging hatch on the tank that is used during manual level measurements. Change GVH140 to equal the reference height. Note! GVH141 "Dip Point Offset" will automatically change to reflect the difference in height between the reference height and the NMS5 reference position.

Two different types of density measurement are available when ordered from Endress+Hauser. • Spot density measurement for up to 3 liquid phases • Density profile measurement 1. Tank profile for up to 16 points for total liquid height. 2. Tank profile for upper phase liquid only. 3. Tank profile based on a manually entered profile parameter. 7.6.1 Spot Density Measurement Spot measurement for up to 3 liquid phases is an option that is available when ordered from Endress+Hauser. The following preconditions are required in order to assure safe and accurate operation. • NMS5 must be configured for Spot density measurement as ordered from Endress+Hauser. For information regarding upgrading your NMS5, contact Endress+Hauser. • Density values: Figure. 67: Density Measurement – Density values can be viewed and changed at the following matrix positions: G0V0H5 Upper Density G0V0H6 Middle Density G0V0H7 Density Bottom • The displacer is balanced at liquid level and the liquid surface is not moving. For spot density measurement, the following parameters can be set or selected. However the factory default settings also can be used. Operation Select the measurement of the density desired from UPPER DENSITY, MIDDLE DENSITY, or DENSITY BOT- TOM at G0V2H0 "OPERATION". NMS5 raises the displacer up out of the liquid, measures its weight, and sends the displacer down to measure the density. After density is measured, the displacer remains at that posi- tion until UP or LEVEL command are selected at G0V2H0. Matrix Item Setting G1V4H3 Displacer Raise Density Set distance (0-300mm) for displacer to rise the level position above during measuring density. Default setting = 150 mm.

7.6.2 Density Profile Measurement Tank Profile Density Measurement In addition to the preconditions, the following additional preconditions are required in order to assure safe and accurate operation for the density measurement of the tank profile. Access Code 51 is required to edit parameters. • NMS5 must be configured for Spot & Profile density measurement as ordered from Endress+Hauser. Contact Endress+Hauser for the information regarding upgrading NMS5. • The standard tank bottom level (GVH004) is zero. If not, the formula used for calculating the interval between profiles is GVH000 / GVH841. The displacer touches the bottom of the tank before measuring a lower level (e.g. 884mm). • If Bottom Level is not 0 mm, select Manual I/F Profile at GVH840. Set GVH843 I/F Manual Level = actual bottom level e.g. 884mm. In this case, the intervals will be calculated based on GVH000 - GVH843/ GVH841. • The density profile can be operated when the liquid is still in the tank. However, depending on the height of liquid level, it may take 1 hour or more to operate the density profile. Note! Additional matrix parameter settings are required for remote communications via WM550 communications protocol. Refer to Section "13. Matrix, (Dynamic Matrix, Device Data : G2), WM550 DENS. SEL.". Matrix Item Setting G1V5H4 Safe Density Select the desired resultant condition when density profile measurement fails due to displacer reaching the low-limit for density profile operation (set in G1V5H5). Selecting "ON" will result in STOP operation. Select- ing "IGNOR" will result in "LEVEL" operation, displacer will return to liq- uid level. Selecting "OFF" will leave the displacer at the position where density profile measurement failed, and in "DENSITY" operation.

NMS5 has a superb self-diagnosis function which monitors its operation. If an error is occurred, the corre- sponding message is displayed on the LCD. The selected matrix position and the error message are displayed every few seconds alternatively. Data can be accessed while the selected matrix position is displayed. The error messages are stored in the memory of NMS5. Matrix position GVH=037 provides the diagnostic history. 10.1 Selection of Diagnostic Code and History Item Procedure Remarks Static Matrix : G0 Figure. 83: Static Matrix Touch Control Figure. 84: Touch Control 1. On "MORE FUNCTION" , select item GVH=036 "DIAGNOSTIC CO." 2. Previous static matrix records are sequentially displayed in Static Matrix screen GVH=037, start- ing with the latest record. Up to 100 alarm records can be saved. If the num- ber of records exceeds 100, it is sequentially overwritten starting with the oldest record. For example, 973192238 2402 means that an error occurred at 22:38 on March 19, 1997, when the instrument temperature was 24 oC and this is the second error since NMS5 was installed. Display includes the year, month, day, hour, minute, instrument temperature, and an error sequential number, in this order. • Item GVH=037 only shows error message, calendar, and pointer, but no label on the LCD.

repair or calibration. • Remove all residue. Pay special attention to the gasket grooves and crevices where fluid may be present. This is especially important if the fluid is corrosive, poisonous, carcinogenic, radioactive, or otherwise hazardous. • Always enclose a duly completed "Declaration of Hazardous Material and De-contamination" form (a copy of the “Declaration of Hazardous Material and De-contamination” is included at the end of this operating manual). Only then can Endress+Hauser transport, examine, and repair a returned device. • Enclose special handling instructions if necessary, for example a safety data sheet as per EN 91/155/EEC. Additionally specify: • An exact description of the application • The chemical and physical characteristics of the instrument • A short description of the error that occurred (specify the error code where possible) • Operating time of the device Caution! • Hazardous materials may be attached to damaged parts of NMS5 or its plastic material. Unless hazardous materials are completely removed from NMS5, no repair request is accepted. • Incomplete cleaning of the instrument may result in waste disposal or cause harm to personnel (burns, etc.). Any costs arising from this will be charged to the operator of the instrument. 10.8 Disposal In case of disposal, separate the various components according to their materials. 10 Diagnosis and Troubleshooting

11.1 Shape, Diameter, and Material 11.1.1 Displacer There are several types of displacer available for NMS5. • The standard type has cylindrical shape and a diameter of 50 mm. Diameters from 30 to 50 mm are optional. • Cylindrical shape is used for viscous liquids. It is also effective if the stilling well is not smooth on its interior surface. Displacer weight and volume depend on the application. Thin displacers are suited for level measurement, thicker ones for bottom level, interface level, and density measurement. A counterweight is optional for heavy turbulence (inquire). Displacers of three different materials are provided. • The standard material is stainless steel SUS316. • Alloy C and PFA are optional for corrosive liquids. • Solid PFA, however, is not applied for flammable liquids. The following size of displacer will be supplied, when you order custody transfer approval. Note! NMi (Netherlands).................70mm PTB (Germany).......................110mm 11.1.2 Measuring Wire • The standard material of the measuring wire is stainless steel SUS316L. • Alloy C and PFA coated stainless steel SUS316 are for corrosive liquids. The following specification of measuring will be supplied when ordering the custody transfer approval. Note! • Select SUS316L (0.15mm) for NMi and PTB specifications. • Refer to the separate "Techenical Information TI00452G" for displacer selection information and Appendix "14.3 Displacer" in this chapter. 11 Displacer and Measuring Wire

Static Matrix Figure. 90: Static Matrix 2. Previous static matrix records are sequentially displayed in Static Matrix screen GVH=035, starting with the latest record. Up to 100 alarm records can be saved. If the number of records exceeds 100, it is sequentially overwritten starting with the oldest record. The display includes the year, month, day, hour, min- ute, instrument temperature, and an error sequential number, in this order. For example, 97 3192238 2402 means that an error occurred at 22:38 on March 19, 1997, when the instrument temperature was 24 oC and this is the second error since NMS5 was installed.

11.4 Hall Sensors After exchanging CPU module, detector unit, wire drum, measuring wire (all or part), it is necessary to adjust the hall sensors and make new weight table calibration. 1. Move the displacer to the side of calibration window or the maintenance chamber window (top of the tank) or put the displacer on a work bench so that the displacer can be touched. Figure. 91: Hall Sensor Adjustment 1 2. Confirm that NMS5 is level and no vibration or other disturbance occurred. • Access Code 530 • Set Operation = STOP • Set GVH030 = Adj. Sensor 3.
