1 Safety Instructions

1.1 Designated use

The Varec Model 7532 Radar Tank Gauge (RTG) is a compact radar level transmitter for the continuous, contactless measurement of liquids, pastes and sludge in stilling wells. The device can also be freely mounted outside closed metal vessels because of its operating frequency of about 6 GHz and a maximum radiated pulsed energy of 1mW (average power output 1 µW). Operation is completely harmless to humans and animals.

1.2 Installation, commissioning and operation

The 7532 RTG has been designed to operate safely in accordance with current technical, safety and EU standards. If installed incorrectly or used for applications for which it is not intended, however, it is possible that application-related dangers may arise, e.g. product overflow due to incorrect installation or calibration. For this reason, the instrument must be installed, connected, operated and maintained according to the instructions in this manual: personnel must be authorised and suitably qualified. The manual must have been read and understood, and the instructions followed. Modifications and repairs to the device are permissible only when they are expressly approved in the manual.

1.3 Operational safety

3.3.2 Engineering tips

Measuring conditions

• The measuring range starts at the bottom end of the stilling well.

• In case of media with a low dielectric constant (groups A and B), the pipe end can be visible through the medium at low levels. In order to guarantee the required accuracy in these cases, it is recommended to position the zero-point at a distance C above the tank bottom (see Fig.).

• In applications with planar or parabolic antennas, especially for media with low dielectric constants (see page 15), the end of the measuring range should not be closer than 1 m (40”) to the flange.

•For overspill protection, it is possible to define a safety distance (SD) additionally to the blocking distance (BD).

• This safety distance (SD) is set to 0.5 m (20") by default and generating an alarm in case the level rises inside the safety distance.

• Distance B defined the smallest recommended measurement range.

• Depending on its consistence, foam can either absorb microwaves or reflect them off the foam surface. Measurement is possible under certain conditions.

Behaviour if measuring range is exceeded

The behaviour in case of the measuring range being exceeded can be freely set: the default setting is a current of 22 mA and the generation of a digital warning (E681).

14 Installation and Operations Manual

Page 15

7532 Mounting

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.

Product class DK (εr) Examples

A 1.4 … 1.9 non-conducting liquids, e.g. liquefied gas

B 1.9 … 4 non-conducting liquids, e.g. benzene, oil, toluene, …

C 4 … 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, e.g. always use a stilling well.

3.4 Installation instructions

3.4.1 Mounting kit

In addition to the tool needed for flange mounting, you will require the following tool:

• 4 mm Allen wrench for turning the housing.

3.4.2 Installation in stilling well

Optimum mounting position for 7532 RTG

Standard installation

When mounting in the stilling well, please observe engineering tips on page 14 and the following points:

• After mounting, the housing can be turned 350° in order to simplify access to the display and the terminal compartment.

• planar axis vertical to flange.

• Measurements can be performed through an open ball valve without any problems.

Recommendations for the stilling well

• Metal (no enamel coating, plastic on request).

•Constant diameter.

• Weld seam as smooth as possible and on the same axis as the slots.

• Slots offset 180° (not 90°).

• Slot width respectively diameter of holes max. 1/10 of pipe diameter, de-burred. Length and number do not have any influence on the measurement.

• Select antenna extension as big as possible. For intermediate sizes (e.g. 180 mm) select next larger antenna extension and adapt it mechanically. Maximum gap allowed between the antenna/horn of 7532 RTG and the inside of the stilling well is 5 mm (3/ 16").

• The antennna extension of the 7532 RTG is mounted with defined pressure. It is strongly recommended not to dismantle this antenna.

• Dimensions of a nozzle for manual gauging must be adapted to the dimensions of the horn antenna used, compare to page page 23.

Stilling wells with pipe expansion

• When using a 7532 RTG, a gradual pipe expansion from DN150 to DN200 / DN200 to DN250 / DN250 to DN300 is acceptable. In such cases, the top end of the piping must have a minimum length of 0.5 m in front of the expansion (see table on page 18). Ideally, a dip socket is used for this.

• Greater expansion of the piping (e.g. DN150 to DN300) is possible if the top end of the pipe is extended accordingly (see table on page 18).

• Avoid pipe expansions at right angles.

7532 Operation

5.1.1 General structure of the operating menu

The operating menu is made up of two levels:

• Function groups (00, 01, 03, …, 0C, 0D): The individual operating options of the instrument are split up roughly into different function groups. The function groups that are available include, e.g.: "basic setup", "safety settings", "output", "display", etc.

• Functions (001, 002, 003, …, 0D8, 0D9): Each function group consists of one or more functions. The functions perform the actual operation or parameterization of the instrument. Numerical values can be entered here and parameters can be selected and saved. The available functions of the “basic setup (00)” function group include, e.g.: "tank shape (002)", "medium property (003)", "process cond. (004)", "empty calibr. (005)", etc.

If, for example, the application of the instrument is to be changed, carry out the following procedure:

1.Select the “basic setup (00)” function group.

2.Select the "tank shape (002)" function (where the existing tank shape is selected).

5.1.2 Identifying the functions

For simple orientation within the function menus (see page 91), for each function a position is shown on the display.

The first two digits identify the function group:

• basic setup 00

• safety settings 01

• linearization 04

…

The third digit numbers the individual functions within the function group:

• basic setup 00 → • tank shape 002

• medium property 003

• process cond. 004

…

Here after the position is always given in brackets (e.g. "tank shape" (002)) after the described function.

To successfully commission a precise measurement to the nearest mm, it is important you carry out a history reset on first installation after mechanical installation and after the basic setup of the device (see Page 56). Only after a history reset the mounting cali- bration is carried out. Enter the measurement offset as the first point in the dip table for the mounting calibration. When a value is dipped at a later date, make a second entry into the dip table, again using the semi-automatic mode. This way, you can easily carry out a linearization of the measurement. When configuring the function in "basic setup" (00) please take into account the following notes:

• Select the functions as described on page 31.

• Some functions can only be used depending on the parameterization of the instrument. For example, the pipe diameter of a stilling well can only be entered if "stilling well" was selected beforehand in the "tank shape" (002) function.

• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirm your data entries. Press function is now started.

• If you do not press a key during a configurable time period (→ function group "display (09)"), an automatic return is made to the home position (measured value display).

Note!

• The instrument continues to measure while data entry is in progress, i.e. the current measured values are output via the signal outputs in the normal way.

• If the envelope curve mode is active on the display, the measured values are updated in a slower cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring point has been optimized.

• If the power supply fails, all preset and parameterized values remain safely stored in the EEPROM.

Microwaves propagate slower in pipes than in free space. This effect depends on the inside diameter of the pipe and is automatically taken into account by the 7500 RTG. It is only necessary to enter the pipe diameter for applications in a bypass or stilling well. If mounting the 7532 RTG on stilling wells with a widening of the pipe, the inner diameter of the lower part of the pipe (d2 in the Fig.) must be entered. This is the part of the stilling well, where the measurement is actually performed.

Using this function, you can either enter a dip table or carry out an auto-correction.

Function "auto-correction" (031)

⇒

–

When measuring levels with radar systems, so-called "multipath reflections" can affect the level signal giving rise to serious measuring errors. "Multipath reflections" also include radar beams which are received by the radar system, which have not been reflected directly by the medium surface. They may reach the antenna via the basin wall and the medium surface. This phenomenon is particularly noticeable with devices mounted near to walls, as soon as the conical radar beam strikes the basin wall. The 7500 RTG can automatically discover and correct measuring errors due to this "multiple path" propagation. This is because it uses two independent sets of information when evaluating reflection signals:

• Firstly, it evaluates the amplitude of the reflected energy using the so-called envelope curve system.

• Secondly, it evaluates the phase of the reflected energy.

The decisive factor for a constant output signal is to assign the phase values to the associated level values. This assignment is ensured using a correspondence table (index correction table). The 7500 RTG learns this for the specific application after installation (learning period). Therefore, after mounting the device, and after completing the basic calibration, a history reset must be performed (enter "yes" in the "history reset" (009) function in the "basic setup " (00) function group). Do not switch off the radar system during filling and emptying operations during the teach-in phase. Switching off when there are only negligible level changes produces no error.

Caution!

During the learning period, fast filling/emptying or turbulent surfaces can result in switching off and on the phase evaluation. Subsequently observed measurement errors will disappear as soon as tank levels come back to areas measured by 7500 RTG previously with activated phase evaluation. If the observed measurement errors are curetted by dip table entries, the 7500 RTG will take care of these corrections and automatically adjust the index correction table. Do NOT calibration or the extended calibration.

Note!

Immediately after installation, the 7500 RTG measures with the specified mm-accuracy. Until the level range has been completely covered by the medium (setting up the

correction table), the maximum permissible filling speed is 100 mm level change / min. After this, the fill speed has no limitation.

Function "pipe diam. corr." (032)

⇒

–

For level measurement in stilling wells, radar systems require highly precise pipe inner diameter data. An mm-exact level measurement cannot be guaranteed for deviations from the actual stilling well inner diameter of more than ± 0.1mm to the value entered in the function group "basic setup" (00). The errors which occur as a result are linear and can be corrected with a dip table containing at least two entries. The 7500 RTG also has an automatic pipe inner diameter correction. This adjusts the entered stilling well inner diameter (input in the function group "basic setup" (00)) to the actual values. However, this presupposes that the value entered in the function group "basic setup" (00) matches the actual pipe inner diameter accurately as possible. The user-defined value entered in the function group "basic setup" (00) can be c o rrec t e d wit h t h is v a l u e. In o r der t o d o thi s , s wit c h o n the "pipe diam. corr."

The pipe diameter, which the instrument determines automatically, will then be transmitted to the "pipe diameter" (007) function.

Note!

Only if the "pipe diameter" (007) function has changed its value, it is necessary to perform a "history reset" (009) and to delete the dip table after activation of the "pipe diam.

Dip table

The dip table is used to correct the level readings of the 7500 RTG using independently taken hand dips. The dip table is used in particular to adapt the level gauge to the specific application conditions as mechanical offset and tank/stilling well design. Depending on national regulations, national inspectors will dip the tank at one to three levels during a calibration run and check the level readings. Only one value pair must be entered into the dip table to correct the measurement offset. If a second value pair is entered into the dip table, the 7500 RTG accepts the corrected measured values identically for both value pairs. All other measured values are determined by linear extrapolation. If you enter more than two value pairs, the system carries out a linear interpolation between adjacent value pairs. Outside these value pairs, extrapolation is also linear.

Figure 8: Alternative procedures to fill the dip table.

To collect and enter data into the dip table, two alternative procedures may be carried out. In order not to mix up measurement values corrected by the offset or linearization of the dip table with uncorrected measurement values, it is recommended to use the semi-automatic mode of the dip table to enter new data pairs. In this case, the first dip value should be entered immediately after the basic calibration. Further linearization points should be entered only after a level change of at least 2 m (see Figure 8:, preferred choice) and a deviation between the "uncorrected measurement value" and the hand dip value of at least 4mm. If this procedure can not be followed, then NO value pair should be entered into the dip table after basic calibration. Measurement data and hand dip values should be collected over the full measurement range and be evaluated with regard to a good linear fit. Only then characteristic value pairs should be entered into the dip table using the "manual mode" (see Figure 8:, right side). If further linearization is needed, further hand dip values should be entered using only the "semi-automatic mode".

L00-FMR53xxx-19-00-00-en-014

Note!

The offset should NOT be determined and entered within the close range of the antenna (conf. definition of the safety distance) or immediately in the range of the tank bottom, because within these ranges interferences of the radar signal may occur.

7532 Maintenance

7 Maintenance

The 7500 RTG measuring instrument requires no special maintenance.

Exterior cleaning

When cleaning the exterior of measuring devices, always use cleaning agents that do not attack the surface of the housing and the seals.

Replacement

After a complete 7500 RTG or electronic module has been replaced, the parameters can be downloaded into the instrument again via the communication interface. Prerequisite to this is that the data were uploaded to the PC beforehand using the ToF Tool / Commuwin II. Measurement can continue without having to carry out a new setup.

• You may have to activate linearization

• You may need to record the tank map again

After an antenna component has been replaced, a new calibration must be carried out.

10 Technical data

10.1 Technical data at a glance

Application

Application The 7500 RTG is used for highly accurate level measurement in

storage tanks and can be applied in custody transfer applications. It meets the relevant requirements according to OIML R85 and API 3.1B.

• The 7532 RTG with planar antenna is specifically and only suited for stilling well applications with ranges up to 38 m (124 ft).

Function and system design

Measuring principle The 7500 RTG is a "downward-looking" measuring system, operating

based on the time-of-flight method. 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.

Equipment architecture The 7500 RTG can be used for measurement in a stilling well as well

as in free space. The different instrument versions are applied as follows:

• The 7532 RTG with planar antenna is the preferred device in stilling wells

• The instruments are equipped with a passive 4…20 mA output with

≥ 150 mm.

HART protocol.

Input

Measured variable The measured variable is the distance between a reference point

(mounting flange) and a reflective surface (e.g. medium surface). The measured value and all parameters are displayed using either metrical SI-units or US/UK-units (inch, ft, …). The level is calculated based on the tank height entered. The level can be converted into other units (volume, mass) by means of a linearization. In order to compensate for non-linear effects like movement of the tank roof, an additional correction table (diptable) can be entered.

Measuring range Seepage15

Output

Output signal 4…20 mA with HART protocol:

this version can be operated via the PC operating software ToF Tool and Commuwin II. The instrument supports both point-to-point and multidrop operation.

Proof of accuracy for custody transfer versions

According to OIML R85:

• Temperature = –25…+55 °C (-13…+131 °F)

• Atmospheric pressure

• Relative humidity (air) = 65 % ±15%

• Medium properties: e.g. medium with good reflectivity and calm surface.

• Tank diameter: signal beam hits the tank wall only at one side.

Note!

No major interference reflections inside the signal beam.

Absolute accuracy: 0.5 mm (2σ value) Inventory Control Versios: ±3 mm

The accuracy of each 7500 RTG is established through a calibration certificate that records the absolute and relative error at 10 equidistant points during the final test. For stilling well measurements with 7532 RTG, a NMI / PTB calibrated tape with an absolute accuracy of 0.25 mm is used. Each 7500 RTG is delivered with the PTB and NMi type approval. Additional initial factory verifications for custody applications are available on demand for all 7500 RTG.

11.4 Function and system design

11.4.1 Measuring principle

The 7500 RTG is a "downward-looking" measuring system, operating based on the time-of-flight method. 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.

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® software based on many years of experience with time-of-flight technology. The mm-accuracy of the 7500 RTG is achieved with the patented algorithms of the PhaseMaster® software. The distance D to the product surface is proportional to the travel time 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

Reference point for "E" is the lower surface of the process connection. The 7500 RTG is equipped with functions to suppress interference echoes. The user can activate these functions. They ensure that interference echoes (e.g. from edges and weld seams) are not interpreted as level echo.

Output

The 7500 RTG is commissioned by entering an empty distance E (=zero), a full distance F (=span), and an application parameter. The application parameter automatically adapts the instrument to the measuring conditions. The data points “E” and “F” correspond with 4mA and 20mA for instruments with current output. They correspond with 0 % and 100% for digital outputs and the display module. A linearization with max. 32 points, based on a table entered either manually or semiautomatically, 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.

11.4.2 Equipment architecture

Stand-alone

The 7500 RTG can be used for measurement in a stilling well as well as in free space. The different instrument versions are applied as follows:

• The 7532 RTG with planar antenna is the preferred device in stilling wells ≥ 150 mm.

• The 7530 RTG with horn antenna can be used in stilling wells with a diameter <150 mm. However, for these diameters no custody transfer approval is available.

• The 7533 RTG with parabolic antenna is preferred for free-space measurements. The 7530 RTG with horn antenna can be used as an alternative for small nozzle diameters.

• The 7531 RTG with rod antenna (PTFE) should be used for measurements of highly aggressive media (e.g. sulphur).

• The instruments are equipped with a passive 4…20 mA output with HART protocol.

7532 Appendix

On-site operation:

• with display and operating module VU 331,

• with a Personal Computer, FXA 193 and the operating software ToF Tool. The ToF Tool is a graphical operating software for instruments from Varec that operate based on the time-of-flight principle (radar, ultrasonic, guided micro-impulse). It assists with commissioning, securing data, troubleshooting, and documentation of the measuring point.

Remote operation:

• with HART handheld DXR 35,

• with a Personal Computer, Commubox FXA 191 and the operating software COMMUWIN II respectively ToF Tool.

• With a Personal Computer, TSM (Tank Side Monitor) and the operating software FuelsManager.

System integration via Rackbus

Multiple 7500 RTG (or other instruments) can be connected to a higher-level bus system via a Gateway ZA:

• Every HART transmitter via one interface module FXN 672 each.

• Gateways are available for MODBUS, FIP, PROFIBUS, INTERBUS etc.

• Both on-site as well as remote operation are possible.

Integration into the Asset Management System

The HART interface allows the integration into the AMS® (Asset Management System) from Fisher-Rosemount.

11.4.3 Custody transfer mode

7500 RTG is a weight and measure approved level transmitter. Either the innage or the ullage can be selected as the custody transfer variable.

The selected variable is the basis for the subsequent calculation of the current amount of product in a tank, along with other measured variables such as (average) temperature and pressure.

This opens up numerous application options in custody transfer:

• Quantity calculation of mineral oils

• Quantity calculation of alcohols

Essentially, this proves that the devices are must not, however, be used in custody transfer mode straight away.

The measuring device is not approved until after the Standards Authorities. For this, the device's level measurement is compared with the tank gauging by a National Standards Authorities inspector using manual dips (also "Initial verification"). As a rule, a quiescent tank gauging is dipped by hand three times in a row and then compared with the value displayed by the level radar. Depending on national regulations, the transfer error limit, calculated as the arithmetic mean of the absolute deviations of all three measurements, must not exceed double the limit of error in legal metrology (compare, for example, the German "Eichordnung" or the American "API 3.1B", in which the necessary procedures are also defined).

Depending on national regulations, this test is repeated with various tank gaugings. Using linearization tables to compensate any non-linearities that occur in measurement is permitted. For this, the 7500 RTG level radar offers a special dip table, compare “Mounting calibration with VU 331” on page 57.
