4.1 Shape, diameter, and material 4.1.1 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 measure- ment, 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. NMi (Netherlands).................Ø70 (2.76) PTB (Germany).......................Ø110 (4.33) 4.1.2 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. • Select SUS316L (0.15mm) for NMi and PTB specifications. • Refer to the separate "Techenical Information TI00452G" for displacer selection information and Appendix "15.3 Displacer" in this chapter. 4 Displacer and measuring wire

Depending on the type of tank and application, different installation procedures are recommended for NMS5. Type of tanks Without guide system With stilling well With guide wires fixed roof tank Floating roof tank Covered floating roof tank Pressurized or bullet tank Tank with agitator or heavy turbulence 5 Installation

• Guide wires cannot be installed in a floating roof tank. When the measuring wire is exposed to free space, it may break due to an external shock. • Installing guide wires is not allowed in pressurized tanks because the wires would prevent closing the valve for replacing the wire, wire drum, or displacer. NMS5 installation position is important for applications without the guide wire system in order to prevent the measuring wire from being bro- ken (refer to Alignment of NMS5 for details). • Installing guide wires is not allowed in pressurized tanks because the wires would prevent closing the valve for replacing the wire, wire drum, or displacer. NMS5 installation position is important for applications without the guide wire system in order to prevent the measuring wire from being bro- ken. 5 Installation

The stilling well diameter that is required to protect the measuring wire without disturbing its opera- tion varies depending on the tank height. The stilling well could either be of constant diameter, or nar- rower at its upper part and wider at its lower part. The following figure shows two examples of the lat- ter case, namely a concentric stilling well and an asymmetric stilling well. Figure 18: Mounting with connection pipe A Front view B Side view L1 Length from the center of the calibration window to the upper part of the stilling well L2 Length from the center of the calibration window to the bottom of the stilling well L3 Length from the center of the calibration window to the bottom of the flange D1 Diameter of upper part of stilling well D2 Diameter of stilling well d Diameter of displacer p(Lx) Longitudinal wire position from the center of the flange r Radial direction offset L1 L2 L1 L2 A B L3 L3 D� D� d r D� d D� p (Lx) 5 Installation

For JIS 10K 150A RF, the dimension is 99 mm (3.9 in) and the flange thickness is 22 mm (0.87 in). • When using an asymmetric stilling well, take into account the lateral shift of the displacer and fol- low the NMS5 mounting direction as shown in the figure. • To calculate the required stilling well diameters, the formula below should be used. The following tables contain the necessary parameters in order to calculate the dimensions of the stilling well. Be sure to have appropriate dimensions of the stilling well according to each dimension in the table. • The radial direction offset is required for only the 47 m (154.2 ft) wire drum. For all other drums, the offset is 0 mm/in. L1 L2 L1 L2 A B L3 L3 D� D� d r D� d D� p (Lx) 5 Installation

The dimension of D2 has to be the larger value of the dimensions D1 and D2b. See the graph above. Concentric pipe Example: L2 = 20 000 mm, d = 50 mm, s = 5.0, 28 m drum Asymmetric pipe Example: L2 = 20 000 mm, d = 50 mm, s = 5.0, 28 m drum Recommendations for mounting stilling well Follow the recommendations for mounting NMS5 with stilling well: • Keep the pipe connection welds smooth. • When 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 prevent corrosion. • Keep the pipe as vertical as possible. Check using a plumb bob. • 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 in the direction of the lateral motion. • Observe the recommendations as per API MPMS chapter 3.1B. • Confirm grounding between NMS5 and the tank nozzle.

1. Install NMS5 [1] on the reducer plate. 2. Perform calibration steps before the displacer [3] is attached to the guide wires. • Make sure that the displacer does not touch the guide wires during calibration. This could be done by mounting the NMS5 to the reducer plate [2] prior to fitting the guide wires [4]. Perform calibration steps so that displacer does not touch the guide wires if the guide wires are already installed to the reducer plate. 3. Secure the guide wires to the hooks of the springs [5]. 4. Secure the springs to the reducer plate. 5. Put the guide wires through the displacer guide ring [6] and set the displacer. This completes the guide wire installation procedure.

5.6.1 Flange Confirm that the size of the nozzle and the flange is matched prior to mounting NMS5 on the tank. The flange size and the rating of NMS5 vary depending on the customer’s specifications. • 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, make sure that the displacer does not touch the inner wall of the nozzle. Figure 23: Allowable inclination of mounting flange 1 Nozzle When NMS5 is installed without a guide system, follow the recommendations below: • Confirm the mounting nozzle is in the sector between 45 and 90 degrees (or -45 and -90 degrees) away from the inlet pipe of the tank. This prevents heavy swinging of the displacer caused by waves or turbulence from the inlet liquid. • Confirm the mounting nozzle is 500 mm (19.69 in) or more away from the tank wall. • Confirm the minimum measuring level is at 500 mm (19.69 in) or more above the top of the inlet pipe by setting the low stop. This protects the displacer from direct flow of the inlet liquid. • If a stilling well cannot be mounted in the tank due to the shape or condition of the tank, attaching a guide system is recommended. Consult E+H services for further information. +1° -1° 1 5 Installation

1 Inlet pipe 2 Tank nozzle • Before pouring liquid into the tank, confirm that liquid flowing through the inlet of the pipe will not contact the displacer directly. • When discharging liquid out of the tank, ensure that the displacer will not get caught in the liquid current and sucked into the outlet pipe. 5.7 Electrostatic charge When liquid measured by NMS5 has a conductivity of 1 uS/m or less, it is quasinonconductive. In this case, using a stilling well or guide wire is recommended. This releases the electrostatic charge on the liquid surface. �500 90° -90° 0° 45° -45° 1 1 �500 2 2 5 Installation

The NMS5 is delivered in two different packing styles depending on the mounting method of the dis- placer. • For the all-in-one method, the displacer is mounted on the measuring wire of NMS5. • For the displacer shipped separately method, it is necessary to install the displacer on the measuring wire inside NMS5. 5.8.1 Available installations The following installation procedures are available for NMS5. • Mounting without guide system • Mounting with stilling well • Mounting with guide wire NMS5 is shipped as an all-in-one package when selected order codes meet all the following conditions: • Feature 070: C or L • Feature 090: A, C, E, G, J, L, N, Q or S • Feature 110: D • Feature 120: 0, 1, 2, 3, 6 or 8 • Feature 130: A, C, D, G, H, J, L, M, T or U Mounting option Without guide system (Free-space mounting) With stilling well With guide wire Type of tanks Type of installations • All-in one • Displacer shipped sepa- rately • Displacer installation through calibration win- dow • All-in one • Displacer shipped sepa- rately • Displacer installation through calibration win- dow Displacer shipped separately 5 Installation

As NMS5 is protected by some packaging materials, remove them as follows prior to mounting NMS5. Figure 25: All-in-one method 1 Fixing band 2 Displacer holder 3 Tape 4 Wire drum stopper 5 Drum housing cover Step Procedure Note 1 1. Hold the gauge so that it stays horizontal against the flange. 2. Cut the fixing bands [1]. 3. Remove the displacer holder [2]. • Perform these steps before mounting NMS5 on the nozzle. • Do not tilt NMS5 after removing the displacer holder. 2 4. Mount NMS5 on the nozzle. • Make sure that the measuring wire hangs vertically. • Confirm that there are no kinks or other defects in the measuring wire. 3 5. Remove screws and M6 bolts (M10 bolts for stainless steel housing) to remove the drum housing cover [5]. 6. Loosen two screws and remove the wire drum stopper [4]. • Be sure not to lose O-ring and fixed bolts for the cover for the drum housing. 4 7. Remove the tape [3] from the wire drum care- fully. • Remove the tape by hand to avoid damaging the wire drum. • Make sure that the measuring wire is wound so that it fits correctly in the grooves. 5 8. Mount the drum housing cover [5]. • Confirm that O-ring is in groove. 6 9. Turn on the main power and confirm that NMS5 shows "STOP" and that level shows "16050 ~16060mm". 10. Set "LEVEL" command, then set "STOP" where the displacer stops 16000mm or less near the 15950 mm level. 11. Set "UP" command and the displacer will automat- ically stop at 16000mm. 12. Set "STOP" command. Sensor, reference, and drum calibration steps are not required because they are all performed prior to delivery. 1 2 3 4 5 5 Installation

7.1.1 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 con- trol"). 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 7.1.2 Functions of operating elements The programming matrix consists of matrix groups, namely one "static" matrix and additional "dynamic" matrices. They are described in detail in Section "14 Matrix". The individual matrix groups, function groups, and functions within the programming matrix can be selected by alternately touching the oper- ating elements.

The section specifies the formula used by NMS5 to calculate levels and densities. Figure 55: 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 tension 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 displacer volume. If this change exceeds the vol- ume tolerance set at matrix position GVH345 "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 T = W - (V + VB) ρb 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 ���������� Measured Displacer Weight Wu Middle Liquid ���������� ���������������������������� ������������� ���������� Measured Displacer Weight Wb Balance ��������B Displacer �������� 7 Operation

• Upper density (Pu) and density profile • Middle density (Pm) • Bottom density (Pb) Draft (distance from liquid surface to the bottom of displacer) 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 56: 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: Displacer Balance Volume (69ml) V2: Displacer Lower Hemisphere Volume V3: Displacer Bottom Stub Volume A: Cross-section of Displacer h : Height of Lower Cone h1: Height of End of Cone For example: standard displacer Ø50.8 (2) cylindrical shape V1: Balance Volume (69ml) V2: Volume of Lower Cone (24.46ml) V3: Volume of End of Cone (0.12ml) A: Cross-section of Displacer (20.26cm2) h1: Displacer Bottom Stub Height (20mm (0.784in)) d h V2 D h1 V3 Liquid Level or Interface 7 Operation

tion, some settings may not be required. Set Access code 51 at GVH039 before applying the initial set- tings. 8.1.1 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. 8.1.2 Density values (GVH005 to 007) Always set GVH005 Upper Density for actual density data, in LPG and any application where the actual density 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 density 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. Minimum difference between phase settings should be at least 0.100 g/ml. GVH005≤GVH006≤GVH007 Example: • GVH005 Upper Density: 0.758/ml • GVH006 Middle Density: 0.880/ml • GVH007 Density Bottom: 1.000/ml 8.1.3 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. GVH141 "Dip Point Offset" will automatically change to reflect the difference in height between the ref- erence height and the NMS5 reference position. CAUTION 8 Commissioning

The following settings are required to display NMT 539 data on NMS5 screens. By setting the HART retry number, it is possible to change the HART communication error detection time of connected Prothermo to suit application needs. When NMS5 cannot read data from Prothermo, it retries. The retry number can be set at the matrix position GVH 773. It is possible to set the number of retries from 0 to 99 by the access code 530. • The factory default HART retry number is 50. This value is suitable for a standard situation where HART recommended cable is used. The detection time for a real error is approx. 17 minutes because HART retry is executed 50 times to determine a real error. • As the number decreases by 1, real errors can be detected faster by approximately 20 seconds. When the HART retry number setting is 0, the detection time of real errors is approx. 40 seconds. However, a false error may occur depending on the installation site conditions. • As the number increases, false errors occur less. However, it takes longer to detect a real error. The detection time for real errors is approx. 34 minutes when the number is set to 99. Item Procedure Remarks Figure 58: Matrix group: service Figure 59: Static matrix 1.

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. 8.6.1 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 representatives. • Density values: Figure 66: Density measurement • Density values can be viewed and changed at the following matrix positions: GVH005: Upper Density GVH006: Middle Density GVH007: 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. Matrix Item Setting GVH143 Displacer Raise Density Set distance (0-300mm) for displacer to rise the level position above during measuring density. Default setting = 150 mm. Observe the rule: GVH143 + GVH144 = 300 n, where n = integer. GVH144 Displacer Submerge Density Set distance (0-300mm) for displacer to submerge the level position above during measuring density. Default setting = 150 mm. Observe the rule: GVH143 + GVH144 = 300 n, where n = integer. e.g. 0.760 g/ml e.g. 0.880 g/ml e.g. 0.1000 g/ml Upper density < Middle density

BOTTOM at GVH020 "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 position until UP or LEVEL command are selected at GVH020. Figure 67: Density measurement 8.6.2 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 inter- val 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. Additional matrix parameter settings are required for remote communications via WM550 communi- cations protocol. Refer to Section "14 Matrix, (Dynamic Matrix, Device Data: G2), WM550 DENS. SEL.". Matrix Item Setting GVH154 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 GVH155).
