Engineering hints
Orientation
Recommended distance (1) wall – outer
edge of nozzle: ~1/6 of tank diameter.
Nevertheless the device should not be
installed closer than 30 cm (12“) to the
tankwall.
Not in the centre (3), interference can cause
signal loss.
Not above the fill stream (4).
It is recommended to use a weather
protection cover (2) in order to protect the
transmitter from direct sun or rain.
Assembly and disassembly is simply done
by means of a tension clamp (→ Chap. 8
on Page 73).
L00-FMR2xxxx-17-00-00-xx-006
Tank installations
Avoid any installations (1), like limit
switches, temperature sensors, etc., inside
the signal beam (refer to beam angle see
"Beam angle" on Page 15).
Symmetrical installations (2), i.e. vacuum
rings, heating coils, baffles, etc., can also
interfere with the measurement.
Optimization options
Antenna size: the bigger the antenna, the
smaller the beam angle, the less
interference echoes.
Mapping: the measurement can be
optimized by means of electronic
suppression of interference echoes.
Antenna alignment: refer to "optimum
mounting position" (see Page 18).
Stilling well: a stilling well respectively a
Wave Guide antenna can always be used to
avoid interference.
Please contact Varec for further
information.

Beam angle
The beam angle is defined as the angle a where the energy density of the radar waves
reaches half the value of the maximum energy density (3dB-width). Microwaves are also
emitted outside the signal beam and can be reflected off interfering installations. Beam

Please use 7230 RTG in stilling well for the measurement of ammonia NH3.
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 case of media with a low dielectric constant (groups A and B), the tank bottom 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 principle it is possible to measure up to the tip of the antenna with 7230 RTG/231/
240. However, due to considerations regarding corrosion and build-up, the end of the
measuring range should not be chosen any closer than A (see Fig.) to the tip of the
antenna.
The smallest possible measuring range B depends on the antenna version (see Fig.).
The tank diameter should be greater than D (see Fig.), the tank height at least H
(see Fig.).
Depending on its consistence, foam can either absorb microwaves or reflect them off
the foam surface. Measurement is possible under certain conditions.

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 maximum
configurable range is 20 m (65 ft) for all 7200 RTG (larger ranges up to 35 m (114 ft) on
request).
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.

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 parameterisation 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:
Select the “basic setup” (00) function group.
Select the "tank shape" (002) function (where the existing tank shape is selected).

Caution!
A reset sets the instrument back to the factory settings. This can lead to an impairment
of the measurement. Generally, you should perform a basic setup again following a
reset.
A reset is only necessary:
if the instrument no longer functions
if the instrument must be moved from one measuring point to another
if the instrument is being de-installed /put into storage/installed

Display and acknowledging error messages
Type of error
Errors that occur during commissioning or measuring are displayed immediately on the
local display. If two or more system or process errors occur, the error with the highest
priority is the one shown on the display.
The measuring system distinguishes between two types of error:
A (Alarm):
Instrument goes into a defined state (e.g. MAX 22 mA)
Indicated by a constant
symbol.
(For a description of the codes, see Page 67)
W (Warning):
Instrument continue measuring, error message is displayed.
Indicated by a flashing
symbol.
(For a description of the codes, see Page 67)
E (Alarm / Warning):
Configurable (e.g. loss of echo, level within the safety distance)
Indicated by a constant/flashing
symbol.
(For a description of the codes, see Page 67)
⇒
5.4.1
Error messages
Error messages appear as four lines of plain text on the display. In addition, a unique
error code is also output. A description of the error codes is given on Page 67.
The "diagnostics" (0A) function group can display current errors as well as the last errors
that occurred.
If several current errors occur, use O or S to page through the error messages.
The last occurring error can be deleted in the "diagnostics" (0A) function group
with the funktion"clear last error" (0A2).
5.5
HART communication
Apart from local operation, you can also parameterise the measuring instrument and
view measured values by means of a HART protocol. There are two options available for
operation:
Operation via the universal handheld operating unit, the HART Communicator DXR 275.
Operation via the Personal Computer (PC) using the operating program (e.g. ToF Tool or
Commuwin II) (For connections, see Page 30).

Note!
The 7200 Radar Tank Gauge can also be operated locally using the keys. If operation is
prevented by the keys being locked locally, parameter entry via communication is not
possible either.

6.3
Basic Setup
The basic setup is sufficient for successful commissioning in most applications.
Complex measuring operations necessitate additional functions that the user can use to
customise the RTG as necessary to suit his specific requirements. The functions
available to do this are described in detail in the BA 221F.
Comply with the following instructions when configuring the functions in the "basic
setup" (00):
Select the functions as described on Page 32.
Some functions can only be used depending on the parameterisation of the instrument.
For example, the pipe diameter of a stilling well can only be entered if "stilling well" was
selected beforVarecand in the "tank shape" (002) function.
Certain functions (e.g. starting an interference echo mapping (053)) prompt you to
confirm your data entries. Press O or S to select "YES" and press F to confirm. The
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 optimised.
If the power supply fails, all preset and parameterised values remain safely stored in the
EEPROM.
"
Caution!
All functions are described in detail, as is the overview of the operating menu itself, in
the manual “Description of the instrument functions − BA 221F”, which is a separate part
of this operating manual.
!
Note!
The default values of the parameters are typed in boldface.

Maintenance
The 7200 Radar Tank Gauge 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.
Replacing seals
The process seals of the sensors must be replaced periodically, particularly if molded
seals (aseptic construction) are used. The period between changes depends on the
frequency of cleaning cycles and on the temperature of the measured substance and the
cleaning temperature.
Repairs
The Varec repair concept assumes that the measuring devices have a modular design
and that customers are able to undertake repairs themselves. Spare parts are contained
in suitable kits. They contain the related replacement instructions. All the spare parts
kits which you can order from Varec for repairs to the 7200 Radar Tank Gauge are listed
with their order numbers on Page 73 and Page 74. Please contact Varec Service for
further information on service and spare parts.
Repairs to Ex-approved devices
When carrying out repairs to Ex-approved devices, please note the following:
Repairs to Ex-approved devices may only be carried out by trained personnel or by Varec
Service.
Comply with the prevailing standards, national Ex-area regulations, safety instructions
(XA) and certificates.
Only use original spare parts from Varec.
When ordering a spare part, please note the device designation on the nameplate. Only
replace parts with identical parts.
Carry out repairs according to the instructions. On completion of repairs, carry our the
specified routine test on the device.
Only Varec Service may convert a certified device into a different certified variant.
Document all repair work and conversions.
Replacement
After a complete 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 beforVarecand using the ToF Tool /
Commuwin II.
Measurement can continue without having to carry out a new setup.
You may have to activate linearisation (see IOM056)
You may need to record the tank map again (see Basic Setup)
After an antenna component or electronic has been replaced, a new calibration must be
carried out. This is described in the repair instructions.

Caution!
Before conformation change with
O or S to the edit mode.
Orientation of the RTG
For orientation a marker is found on the flange or threaded boss of the RTG. During
installation this must be oriented as follows (see Page 10):
In tanks: to the vessel wall
In stilling wells: to the slots
In bypass pipes: vertical to the tank connectors
When using the Wave Guide antenna no orientation is required!
After commissioning the RTG, the echo quality indicates whether a sufficiently large
measuring signal is obtained. If necessary, the quality can be optimised later. Vice versa,
the presence of an interference echo can be used to minimise this by optimum
orientation. The advantage of this is that the subsequent tank mapping uses a
somewhat lower level that causes an increase in the strength of the measuring signal.
Proceed as follows:
#
Warning!
Subsequent alignment can lead to personal injury. Before you unscrew or loosen the
process connection, make sure that the vessel is not under pressure and does not
contain any injurious substances.
It is best to empty the container so that the bottom is just covered. However, alignment
can be carried out even if the vessel is empty.
Optimisation is best carried out with the aid of the envelope graph in the display or the
ToF Tool.
Unscrew the flange or loosen the threaded boss by a half a turn.
Turn the flange by one hole or screw the threaded boss by one eighth of a turn. Note
the echo quality.
Continue to turn until 360° is reached.
Optimum alignment:

Return
The following procedures must be carried out before a transmitter is sent to Varec e.g.
for repair or calibration:
Remove all residue which may be present. Pay special attention to the gasket grooves
and crevices where fluid may be present. This is especially important if the fluid is
dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc.
Always enclose a duly completed "Declaration of contamination" form (a copy of the
“Declaration of contamination” is included at the end of this operating manual). Only
then can Varec 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 product.
A short description of the error that occurred (specify error code if possible)
Operating time of the device.

Input
Measured variable
The measured variable is the distance between a reference point and a reflective surface
(i.e. medium surface).
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.

This value can be reduced for Wave Guide antennas, depending on the length. In the
event of horizontal stress, mechanical support is required or provide the Wave Guide
antenna with a protective pipe.
Cleaning of the antenna
The antenna can get contaminated, depending on the application. 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. Care has to be taken not to damage the
antenna in the process of a mechanical or hose-down cleaning (eventually connection
for cleaning liquid). The material compatibility has to be considered if cleaning agents
are used!
The maximum permitted temperature at the flange should not be exceeded.

Function and system design
11.4.1
Function (Measuring principle)
The RTG is a "downward-looking" measuring system, operating based on the time-offlight 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 Radar Tank Gauge could be achieved with the patented
algorithms of the PhaseMaster® software.
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
IOM054GVAE0204
75
Radar Tank Gauge
Refer to the above figure for the reference point for "E".
The RTG is equipped with functions to suppress interference echoes. The user can
activate these functions. They ensure that interference echoes (i.e. from edges and weld
seams) are not interpreted as level echo.
Output
The 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 process cond.. 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
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.
11.4.2
Equipment architecture
Stand-alone
The RTG M can be used for measurement in a stilling well / bypass as well as in free
space.
