6 Endress+Hauser Function and system design Measuring principle The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight method (ToF). It measures the distance from the reference point (process connection) to the product surface. Radar impulses are emitted by an antenna, reflected off the product surface and received again by the radar system. F L D E R 0% 100% A0017871  1 Setup parameters of the Micropilot R Reference point of the measurement (lower edge of the flange or threaded connection) E Empty calibration ( = zero) F Full calibration (= span) D Measured distance L Level (L = E - D) Input The reflected radar impulses are received by the antenna and transmitted into the electronics. A microprocessor evaluates the signal and identifies the level echo caused by the reflection of the radar impulse at the product surface. The unambiguous signal identification is accomplished by the PulseMaster® eXact software together with the Multi-echo tracking algorithms, based on many years of experience with time-of-flight technology. The distance D to the product surface is proportional to the time of flight t of the impulse: D = c · t/2, with c being the speed of light. Based on the known empty distance E, the level L is calculated: L = E – D The reference point R of the measurement is located at the process connection. For details see the dimensional drawing: • FMR51: →  64 • FMR52: →  70 The Micropilot is equipped with functions to suppress interference echoes. The user can activate these functions. Together with the multi-echo tracking algorithms they ensure that interference echoes (i.e. from edges and weld seams) are not interpreted as level echo.

Endress+Hauser 7 Output The Micropilot is commissioned by entering an empty distance "E" (=zero), a full distance "F" (=span) and application parameters which automatically adapt the instrument to the process conditions. For models with a current output, the factory adjustment for zero point "E" and span "F" is 4 mA and 20 mA. For digital outputs and the display module, the factory adjustment for zero point "E" and span "F" is 0 % and 100 %. A linearization with max. 32 points, based on a table entered either manually or semi-automatically, can be activated locally or remotely. This function provides a measurement in engineering units and a linear output signal for spheres, horizontal cylindrical tanks and vessels with conical outlet.

8 Endress+Hauser Input Measured variable The measured variable is the distance between the reference point and the product surface. The level is calculated from this distance, taking into account the empty distance "E" entered by the user. If required, the level can be converted into other variables (volume, mass) by means of a linearization (up to 32 points). Measuring range Maximum measuring range Device Maximum measuring range FMR51 - standard version 40 m (131 ft) FMR51 - with "Advanced dynamics" application package 70 m (230 ft) FMR52 - standard version 40 m (131 ft) FMR52 - with "Advanced dynamics" application package 60 m (197 ft) Usable measuring range The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the mounting location and eventual interference reflections. The following tables describe the groups of media as well as the achievable measuring range as a function of application and media group. If the dielectric constant of a medium is unknown, it is recommended to assume media group B to ensure a reliable measurement. Media groups Media groups DC (εr) Example A 1.4 to 1.9 non-conducting liquids, e.g. liquefied gas 1) B 1.9 to 4 non-conducting liquids, e.g. benzene, oil, toluene, … C 4 to 10 e.g. concentrated acids, organic solvents, esters, aniline, alcohol, acetone, … D > 10 conducting liquids, e.g. aqueous solutions, dilute acids and alkalis 1) Treat Ammonia NH3 as a medium of group A. For dielectric constants (DC values) of many media commonly used in various industries refer to: • the Endress+Hauser DC manual (CP01076F) • the Endress+Hauser "DC Values App" (available for Android and iOS)

This effect depends on the kind of gas/vapor and of its temperature. This results in a systematic measuring error that gets bigger as the distance increases between the reference point of the measurement (flange) and the product surface. The following table illustrates this measured 1) According to DIN EN IEC 61298-2 / DIN EN IEC 60770-1 the response time is the time which passes after a sudden change of the input signal until the output signal for the first time assumes 90% of the steady-state value. 2) Feature 540 "Application Package", option EM

Gas phase compensation with external pressure sensor (PROFIBUS PA, FOUNDATION Fieldbus) PROFIBUS devices can receive the signal of an external pressure sensor through the bus and use it to perform a pressure dependent time-of-flight correction. In the case of saturated steam in the temperature range from 100 to 350 °C (212 to 662 °f), for example, the measuring error of the distance measurement can be reduced by this method from up to 29 % (without compensation) to less than 3 % (with compensation).

Nevertheless the device should not be installed closer than 15 cm (5.91 in) to the tank wall. • Not in the center (2), as interference can cause signal loss. • Not above the fill stream (3). • It is recommended to us a weather protection cover (1) in order to protect the device from direct sun or rain. Vessel installations A0018944 Avoid any installations (point level switches, temperature sensors, braces, vacuum rings, heating coils, baffles etc.) inside the signal beam.

Endress+Hauser 37 Reduction of interference echoes A0016890 Metallic screens mounted at a slope spread the radar signal and can, therefore, reduce interference echoes. Measurement in a plastic vessel If the outer wall of the vessel is made of a non-conductive material (e.g. GRP), microwaves can also be reflected off interfering installations outside the vessel (e.g. metallic pipes (1), ladders (2), grates (3), ...). Therefore, there should be no such interfering installations in the signal beam. Please contact Endress+Hauser for further information. 2 3 1 A0017123

40 Endress+Hauser Measuring conditions • In case of boiling surfaces, bubbling or tendency for foaming use FMR53 or FMR54. Depending on its consistence, foam can either absorb microwaves or reflect them off the foam surface. Measurement is possible under certain conditions. For FMR50, FMR51 and FMR52, the additional option "Advanced dynamics" is recommended in these cases (feature 540: "Application Package", option EM). • In case of heavy steam development or condensate, the maximum measuring range of FMR50, FMR51 and FMR52 may decrease depending on density, temperature and composition of the steam → use FMR53 or FMR54. • For the measurement of absorbing gases such as ammonia NH3 or some fluorocarbons 3), please use Levelflex or Micropilot FMR54 in a stilling well. • The measuring range begins, where the beam hits the tank bottom. Particularly with dish bottoms or conical outlets the level cannot be detected below this point. • In stilling well applications, the electromagnetic waves do not propagate completely outside the tube. It must be taken into account that the accuracy may be reduced in the area C. In order to guarantee the required accuracy in these cases, it is recommended to position the zero-point at a distance C above the end of the tube (see figure). • In case of media with a low dielectric constant (εr = 1.5 to 4) 4) the tank bottom can be visible through the medium at low levels (low height C). Reduced accuracy has to be expected in this range. If this is not acceptable, we recommend positioning the zero point at a distance C (see figure) above the tank bottom in these applications. • In principle it is possible to measure up to the tip of the antenna with FMR51, FMR53 and FMR54. However, due to considerations regarding corrosion and build-up, the end of the measuring range should not be chosen any closer than A (see figure) to the tip of the antenna. • When using FMR54 with planar antenna, especially for media with low dielectric constants, the end of the measuring range should not be closer than A: 1 m (3.28 ft) to the flange. • The smallest possible measuring range B depends on the antenna version (see figure). • The tank height should be at least H (see table). 100% 0% B A C H øD A0018872 Device A [mm (in)] B [m (ft)] C [mm (in)] H [m (ft)] FMR51 50(1.97) > 0.2 (0.7) 50 to 250 (1.97 to 9.84) > 0.3 (1.0) FMR52 200(7.87) 3) Affected compounds are e.g. R134a, R227, Dymel 152a. 4) Dielectric constants of important media commonly used in various industries are summarized in the DC manual (CP01076F) and in the Endress +Hauser "DC Values App" (available for Android and iOS).

Endress+Hauser 41 Mounting cladded flanges • Use flange screws according to the number of flange holes. • Tighten the screws with the required torque (see table). • Retighten the screws after 24 hours or after the first temperature cycle. • Depending on process pressure and process temperature check and retighten the screws at regular intervals. Usually, the PTFE flange cladding also serves as a seal between the nozzle and the device flange.

Installation in stilling well 1 90° A0016841  15 Installation in stilling well 1 Marking for antenna alignment • For horn antenna: Align the marking towards the slots of the stilling well. • Measurements can be performed through an open full bore ball valve without any problems. • After mounting, the housing can be turned 350° in order to facilitate access to the display and the terminal compartment. Recommendations for the stilling well • Metal (no enamel coating; plastic on request). • Constant diameter. • Diameter of stilling well not larger than antenna diameter. • Diameter difference between horn antenna and inner diameter of the stilling well as small as possible. • Weld seam as smooth as possible and on the same axis as the slots. • Slots offset 180° (not 90°). • Slot width or diameter of holes max. 1/10 of pipe diameter, de-burred. Length and number do not have any influence on the measurement. • Select horn antenna as big as possible. For intermedaite sizes (e.g. 180 mm (7 in)) select next larger antenna and adapt it mechanically (for horn antennas) • At any transition (i.e. when using a ball valve or mending pipe segments), no gap may be left exceeding 1 mm (0.04 in). • The stilling well must be smooth on the inside (average roughness Rz ≤ 6.3 μm (248 μin)). Use extruded or parallel welded metal pipe. An extension of the pipe is possible with welded flanges or pipe sleeves. Flange and pipe have to be properly aligned at the inside. • Do not weld through the pipe wall. The inside of the stilling well must remain smooth. In case of unintentional welding through the pipe, the weld seam and any unevenness on the inside need to be carefully removed and smoothened. Otherwise, strong interference echoes will be generated and material build-up will be promoted. • In the case of smaller nominal widths flanges must be welded to the pipe such that they allow for a correct orientation (marker aligned toward slots).

The emission and reception of microwaves can thus eventually be hindered. The degree of contamination leading to an error depends on the medium and the reflectivity, mainly determined by the dielectric constant εr. If the medium tends to cause contamination and deposits, cleaning on a regular basis is recommended.

Endress+Hauser 85 Integration in tank gauging system The Endress+Hauser Tank Side Monitor NRF590 provides integrated communications for sites with multiple tanks, each with one or more sensors on the tank, such as radar, spot or average temperature, capacitive probe for water detection and/or pressure sensors. Multiple protocols out of the Tank Side Monitor guarantee connectivity to nearly any of the existing industry standard tank gauging protocols. Optional connectivity of analog 4...20 mA sensors, digital I/O and analog output simplify full tank sensor integration. Use of the proven concept of the intrinsically safe HART bus for all on-tank sensors yields extremely low wiring costs, while at the same time providing maximum safety, reliability and data availability.

86 Endress+Hauser SupplyCare inventory management software SupplyCare is a web-based operating program for coordinating the flow of material and information along the supply chain. SupplyCare provides a comprehensive overview of the levels of geographically distributed tanks and silos, for instance, providing complete transparency over the current inventory situation, regardless of time and location. Based on the measuring and transmission technology installed onsite, the current inventory data are collected and sent to SupplyCare. Critical levels are clearly indicated and calculated forecasts provide additional security for material requirements planning. The main functions of SupplyCare: Inventory visualization SupplyCare determines the inventory levels in tanks and silos at regular intervals. It displays current and historical inventory data and calculated forecasts of future demand. The overview page can be configured to suit the user's preferences. Master data management With SupplyCare you can create and manage the master data for locations, companies, tanks, products and users, as well as user authorization. Report Configurator The Report Configurator can be used to create personalized reports quickly and easily. The reports can be saved in a variety of formats, such as Excel, PDF, CSV and XML. The reports can be transmitted in many ways, such as by http, ftp or e-mail. Event management Events, such as when levels drop below the safety stock level or plan points, are indicated by the software. In addition, SupplyCare can also notify pre-defined users by e-mail. Alarms If technical problems occur, e.g. connection issues, alarms are triggered and alarm e-mails are sent to the System Administrator and the Local System Administrator. Delivery planning The integrated delivery planning function automatically generates an order proposal if a pre-set minimum inventory level is undershot. Scheduled deliveries and disposals are monitored continuously by SupplyCare. SupplyCare notifies the user if scheduled deliveries and disposals are not going to be met as planned. Analysis In the Analysis module, the most important indicators for the inflow and outflow of the individual tanks are calculated and displayed as data and charts. Key indicators of material management are automatically calculated and form the basis for optimizing the delivery and storage process. Geographical visualization All the tanks and the tank inventories are represented graphically on a map (based on Google Maps). The tanks and inventory situations can be filtered by tank group, product, supplier or location. Multi-language support The multi-language user interface supports 9 languages, thereby enabling global collaboration on a single platform. The language and settings are recognized automatically using the browser settings. SupplyCare Enterprise SupplyCare Enterprise runs by default as a service under Microsoft Windows on an application server in an Apache Tomcat environment. The operators and administrators operate the application via a Web browser from their workstations.
