4.3.2 Engineering hints

Orientation

• Recommended distance (1) wall – outeredge of nozzle: ~1/6 of tank diameter.Nevertheless the device should not be

installed closer than 30 cm (11.8 in) to thetankwall.

• Not in the centre (3), interference cancause signal loss.

• Not above the fill stream (4).

• It is recommended to use a weatherprotection cover (2) in order to protect thetransmitter from direct sun or rain.Assembly and disassembly is simply doneby means of a tension clamp (page 63).

Tank installations

• Avoid any installations (1), like limitswitches, temperature sensors, etc., insidethe signal beam (see page 18).

• Symmetrical installations (2), i.e. vacuumrings, heating coils, baffles, etc., can alsointerfere with the measurement.

Optimization options

• Antenna size: the bigger the antenna, thesmaller the beam angle, the lessinterference echoes.

• Mapping: the measurement can beoptimized by means of electronicsuppression of interference echoes.

• Antenna alignment: refer to "optimummounting position", page 22.

• Stilling well: a stilling well can always beused to avoid interference.

• Metallic screens (3) mounted at a slopespread the radar signals and can,therefore, reduce interference echoes.

Please contact Varec for further information.

Measurement in a Plastic Tank

If the outer wall of the tank is made of a non-conductive material (e.g. GRP), microwaves canalso be reflected off interfering installations outside the signal beam (e.g. metallic pipes (1),ladders (2), grates (3), …). Therefore, there should be no such interfering installations in thesignal beam.

Please contact Varec for further informatione.

Beam Angle

The beam angle is defined as the angle a where the energy density of the radar waves reacheshalf the value of the maximum energy density (3dB-width). Microwaves are also emitted outsidethe signal beam and can be reflected off interfering installations. Beam diameter W as functionof antenna type (beam angle a) and measuring distance D:

Mounting


• The measuring range begins, where the beam hits the tank bottom. Particularly with dishbottoms 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 bevisible through the medium at low levels (low height C). Reduced accuracy has to beexpected in this range. If this is not acceptable, we recommend positioning the zero pointat a distance C (see Fig.) above the tank bottom in these applications.

• In principle it is possible to measure up to the tip of the antenna with 7230/7231/7240.However, due to considerations regarding corrosion and build-up, the end of themeasuring range should not be chosen any closer than A (see Fig.) to the tip of the antenna

For the Series 7244/7245, the end of measuring range should not be chosen closer than A (seeFig.) to the tip of the antenna, especially if there is development of condensate.

• 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.).

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 (66 ft)

The following tables describe the groups of media as well as the achievable measuring range asa function of application and media group. If the dielectric constant of a medium is unknown, itis recommended to assume media group B to ensure a reliable measurement.

1 Treat Ammonia (NH3)as a medium of group A, that is, use the 7231 series in a stilling well.

Optimum Mounting Position

Standard Installation

For installations in a stilling well, follow the engineering hints and note the following points:

• Marker is aligned towards tank wall.

• The marker is always exactly in the middle between two bolt-holes in the flange.

• Use spring washers (1) (see Fig.).

Note It is recommended to retighten the flange bolts periodically, depending on processtemperature and pressure. Recommended torque: 60 to 100 Nm (44.25 to 73.75 lb/ft).

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

• The inactive part of the rod antenna must extend below the nozzle.

• The rod antenna must be aligned vertically.

6.4 Display and acknowledging error messages

Type of Error

Errors that occur during commissioning or measuring are displayed immediately on the localdisplay. 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 Alarm symbol.(For a description of the codes, see page 70)

• W (Warning):Instrument continue measuring, error message is displayed.Indicated by a flashing Alarm symbol.(For a description of the codes, see page 70)

• E (Alarm / Warning):Configurable (e.g. loss of echo, level within the safety distance)

Indicated by a constant/flashing Alarm symbol.(For a description of the codes, see page 70)

6.4.1 Error messages

Error messages appear as four lines of plain text on the display. In addition, a unique error codeis also output. A description of the error codes, see page 68.

• The "diagnostics" (0A) function group can display current errors as well as the last errorsthat occurred.

• If several current errors occur, use the minus (-) or plus (+) keys to page through the errormessages.

• The last occurring error can be deleted in the "diagnostics" (0A) function group with thefunktion"clear last error" (0A2).

6.5 HART communication

Apart from local operation, you can also parameterize the measuring instrument and viewmeasured values by means of a HART protocol. There are two options available for operation:

• Operation via the universal handheld operating unit, the Field Communicator 375, 475.

• Operation via the Personal Computer (PC) using the operating program (e.g. FieldCare,page 40).

Note The 7200 Series RTG can also be operated locally using the keys. If operation is pre-vented by the keys being locked locally, parameter entry via communication is not possibleeither.

Caution The basic setup is sufficient for successful commissioning in most applications.Complex measuring operations necessitate additional functions that the user can use tocustomise the 72xx RTG as necessary to suit his specific requirements. The functions avail-able to do this are described in detail in the BA00221F/00/EN.

Comply with the following instructions when configuring the functions in the "basic setup" (00)

• Select the functions as described on page 31.

• 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" wasselected beforehand in the "tank shape" (002) function.

• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirmyour data entries. Press O or S to select "YES" and press F to confirm. The function is nowstarted.

• 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 Note the following:

• The instrument continues to measure while data entry is in progress, i.e. the currentmeasured 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 aslower cycle time. Thus, it is advisable to leave the envelope curve mode after themeasuring point has been optimised.

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

• All functions are described in detail, as is the overview of the operating menu itself, in themanual "BA00221F - Description of Instrument Functions", which is found on the enclosedCD-ROM.

• The default values of the parameters are typed in boldface.

Function "empty calibr." (005)

This function is used to enter the distance from the flange (reference point of the measurement)to the minimum level (=zero).

Caution For dish bottoms or conical outlets, the zero point should be no lower than thepoint at which the radar beam hits the bottom of the tank.

Function "full calibr." (006)

This function is used to enter the distance from the minimum level to the maximum level(=span).

In principle, it is possible to measure up to the tip of the antenna. However, due toconsiderations regarding corrosion and build-up, the end of the measuring range should not bechosen any closer than 50 mm (1.97 in) to the tip of the antenna.

Caution If bypass or stilling well was selected in the "tank shape" (002) function, the pipediameter is requested in the following step.

Function "pipe diameter" (007)

This function is used to enter the pipe diameter of the stilling well or bypass pipe.

Microwaves propagate more slowly in pipes than in free space. This effect depends on the insidediameter of the pipe and is automatically taken into account by the 72xx RTG. It is onlynecessary to enter the pipe diameter for applications in a bypass or stilling well.

• Mapping is carried out up to the currently measured echo

• The range to be suppressed is suggested in the "range of mapping" (052) function

It is wise to carry out a mapping even in this case.

• At the moment, an interference is being evaluated

• Therefore, a mapping is carried out including the presently measured echoes

• The range to be suppressed is suggested in the "range of mapping" (052) function

• This error cannot be remedied by interference echo mapping

• Check the application parameters (002), (003), (004) and "empty calibr." (005)

dist. unknown

If the actual distance is not known, no mapping can be carried out.

manual

A mapping is also possible by manual entry of the range to be suppressed. This entry is madein the "range of mapping" (052) function.

Caution The range of mapping must end 0,5 m (1.6 ft) before the echo of the actual level.For an empty tank, do not enter E, but E – 0,5 m (1.6 ft). If a mapping already exists, it isoverwriten up to the distance specified in "range of mapping" (052). Beyond this value theexisting mapping remains unchanged.

Function " range of mapping" (052)

This function displays the suggested range of mapping. The reference point is always thereference point of the measurement (page 44). This value can be edited by the operator.

For manual mapping, the default value is 0 m.

7.5.1 Signal analysis via envelope curve

After the basic setup, an evaluation of the measurement using the envelope curve isrecommended.

Note If the level of echo is very weak or there is a heavy interference echo, an orientationof the 72xx RTG can help optimise the measurement (increase of the useful echo/reductionof the interference echo).

7.5.2 User-specific applications (operation)

8 Maintenance

The 7200 Series RTG measuring instrument requires no special maintenance.

Exterior Cleaning

When cleaning the exterior of measuring devices, always use cleaning agents that do not attackthe 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 ofcleaning cycles and on the temperature of the measured substance and the cleaningtemperature.

Repairs

The Varec repair concept assumes that the measuring devices have a modular design and thatcustomers are able to undertake repairs themselves. Please contact Varec Service for furtherinformation 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 VarecService.

• 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. Onlyreplace 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 72xx RTG or electronic module has been replaced, the parameters can bedownloaded into the instrument again via the communication interface. Prerequisite to this isthat the data were uploaded to the PC beforehand using the FieldCare.

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 carriedout. This is described in the repair instructions.

10.5 Return

The following procedures must be carried out before a transmitter is sent to Varec, that is, forrepair or calibration:

• Remove all residue which may be present. Pay special attention to the gasket grooves andcrevices where fluid may be present. This is especially important if the fluid is dangerous tohealth, 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 thencan Varec transport, examine, and repair a returned device.

• Enclose special handling instructions if necessary, for example a safety data sheet as perEN91/155/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)

• If necessary, give the error code.

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 (32points).

Operating frequency

• C-band

• Up to 8 72xx RTG transmitters can be installed in the same tank because the transmitterpulses are statistically coded.

Transmitting power

Technical Data


Linearization

• The linearization function of the 72xx RTG allows the conversion of the measured value intoany unit of length or volume. Linearization tables for calculating the volume in cylindricaltanks are pre-programmed. Other tables of up to 32 value pairs can be entered manually orsemi-automatically.

11.1.3 Auxiliary energy

Ripple HART

• 47 to 125 Hz: Uss = 200 mV (at 500 W)

Max. noise HART

• 500 Hz to 10 kHz: Ueff = 2.2 mV (at 500 W)

11.1.4 Performance characteristics

Reference operating conditions

• Temperature = +20 °C ±5 °C (+68 °F ±41 °F)

• Pressure = 1013 mbar abs. ±20 mbar (15 psi ±0.29 psi)

• Relative humidity (air) = 65 % ±20%

• Ideal reflector. No major interference reflections inside the signal beam.

Maximum measured error

• Typical statements of measuring range for reference conditions, include linearity,repeatability, and hysteresis:

• Up to 10 m ±10 mm (33 ft ±0.39 in)

• Off 10 m ±0.1 % (33 ft ±0,1 %)

Resolution

• Digital / analog in % 4 to 20 mA: 1 mm (0.04 in) / 0.03 % of measuring range

Reaction time

• The reaction time depends on the parameter settings (min. 1 s). In case of fast levelchanges, the instrument needs the reaction time to indicate the new value.

Influence of ambient temperature

• The measurements are carried out in accordance with EN 61298-3:

Digital output HART:

• average TK: 5 mm (0.2 in)/10 K, max. 15 mm (0.59 in)over the entire temperaturerange -40 °C to +80 °C (-40 °F to +176 °F)

Current output (additional error, in reference to the span of 16 mA):

• Zero point (4 mA):

• average TK: 0,03 %/10 K, max. 0,45 % over the entire temperature range -40 °C to +80°C (-40 °F to +176 °F)

• Span (20 mA):

• average TK: 0,09 %/10 K, max. 0,95 % over the entire temperature range -40 °C to +80°C (-40 °F to +176 °F)

8/12/2019 IOM054_7231_HART_v01.04.00



Varec, Inc. 77

Effect of gas phase

• High pressures reduce the propagation velocity of the measuring signals in the gas/vaporabove the fluid. This effect depends on the gas/vapor and is particularly large for lowtemperatures. This results in a measuring error that gets bigger as the distance increasesbetween the device zero point (flange) and product surface. The following table illustratesthis measured error for a few typical gases/vapors (with regard to the distance; a positive

value means that too large a distance is being measured):

Note When the pressure is known and constant, this measured error can, for example, becompensated by means of linearization.

11.1.5 Operating conditions: Environment

Ambient temperature range:

Ambient temperature for the transmitter:

• -40 °C to +80 °C (-40 °F to +176 °F) or -50 °C to +80 °C (-58 °F to +176 °F).

• The functionality of the LCD display may be limited for temperatures Ta < -20 °C (-4 °F) andTa > +60 °C (140 °F).

A weather protection cover should be used for outdoor operation if the instrument is exposedto direct sunlight.

Technical Data


Cleaning of the antenna

• The antenna can get contaminated, depending on the application. The emission andreception of microwaves can thus eventually be hindered. The degree of contaminationleading to an error depends on the medium and the reflectivity, mainly determined by thedielectric constant er. If the medium tends to cause contamination and deposits, cleaningon 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.

Electromagnetic compatibility

• Electromagnetic compatibility in accordance with all the relevant requirements of theEN61326 series and NAMUR recommendation (NE21). For details refer to the Declaration ofConformity. Maximum deviation < 0.5% of the span.

• A standard installation cable is sufficient if only the analogue signal is used. Use a screenedcable when working with a superimposed communications signal (HART).

11.1.6 Operating conditions: Process

Process temperature range / Process pressure limits

Note The specific range may be reduced by the selected process condition. The pressurerating (PN) specified on the flanges refers to a reference temperature of 20 °C (68 °F), forASME flanges to 100 °F. Observe pressure temperature dependency.

The pressure values permitted at higher temperatures can be found in the following standards

• EN1092-1: 2001 Tab. 18

With regard to their temperature stability properties, the material 1.4404 and 1.4435 aregrouped under 13E0 in EN1092-1 Tab. 18. The chemical composition of the two materialscan be identical.

• ASME B16.5a - 1998 Tab. 2-2.2 F316• ASME B16.5a - 1998 Tab. 2.3.8 N10276
