Check that the specifications of the measuring instrument delivered correspond to the specifications given on the pur-chase order.

The type and the serial number of the transmitter are shown on the nameplate. The transducer type is printed on the trans-ducers.

3.2 General Precautions

FLUXUS is a precision measuring instrument and has to be handled with care. To obtain good measurement results and not damage the measuring instrument, it is important that great attention is paid to the instructions given in this user man-ual, particularly to the following points:

• Protect the transmitter from shocks.

• The housing may only be opened by authorized personnel. The degree of protection of the transmitter will only be en-sured if the front plate is tightly screwed to the housing.

• Keep the transducers clean. Manipulate the transducer cables with caution. Avoid excessive cable bend.

• Make sure to work under correct ambient and operating temperatures. The ambient temperature has to be within the op-erating temperature range of the transmitter and the transducers (see Technical Specification).

• Observe the degree of protection (see Technical Specification).

3.3 Cleaning• Clean the transmitter with a soft cloth. Do not use detergents.

• Remove traces of the coupling compound from the transducers with a soft paper towel.

Attention! Observe the Safety Instructions for the Use in Explosive Atmosphere (see document SIFLUXUS).

5.2 Transducers

5.2.1 Preparation

5.2.1.1 Selection of the Measuring Point

The correct selection of the measuring point is crucial for achieving reliable measurement results and a high measurement accuracy.

A measurement on a pipe is possible if:

• the ultrasound propagates with a sufficiently high amplitude (see user manual – Advanced Functions, section 3.1)

• the flow profile is fully developed (see user manual – Advanced Functions, section 3.2)

The correct selection of the measuring point and the correct transducer positioning guarantees that the sound signal will be received under optimum conditions and evaluated correctly.

Because of the variety of applications and the different factors that influence the measurement, there is no standard solu-tion for the transducer positioning. The measurement is influenced by the following factors:

– diameter, material, lining, wall thickness and shape of the pipe

– fluid

– gas bubbles in the fluid

• Avoid measuring points in the vicinity of deformations or defects of the pipe and in the vicinity of welds.

• Avoid measuring points with deposit formation in the pipe.

• Make sure that the pipe surface at the selected measuring point is even. The pipe may not be corrugated.

• The ambient temperature at the measuring point has to be within the operating temperature range of the transducers (see Technical Specification).

• Select the location of the transmitter within the range of the cable of the measuring point.

• The ambient temperature at the measuring point has to be within the operating temperature range of the transmitter and the sensor (see Technical Specification).

• If the measuring point is within an explosive atmosphere, the danger zone and gases that may be present have to be de-termined. The transducers and the transmitter have to be appropriate for these conditions.

5.2.1.2 Preparation of the Pipe

• The pipe has to be stable. It has to be able to withstand the pressure exerted by the transducer mounting fixture.

Rust, paint or other deposits on the pipe absorb the sound signal. A good acoustic contact between the pipe and the trans-ducers is obtained as follows:

• Clean the pipe at the selected measuring point:

– If present, the paint layer has to be smoothed by sanding. The paint does not need to be removed completely.

– Remove any rust or loose paint.

• Use coupling foil or apply a bead of acoustic coupling compound along the center line of the contact surface of the trans-ducers.

• Observe that there must be no air pockets between the transducer contact surface and the pipe wall.


UMFLUXUSF721BV1-1EN, 2017-01-23 19


5.2.1.3 Selection of the Measurement Arrangement

Diagonal arrangement with 1 beam Reflection arrangement with 1 beam

• wider flow velocity and sound speed range compared to the reflection arrangement

• use in the presence of deposits on the inner pipe wall or with strongly attenuating gases or liquids (1 sound path)

• smaller flow velocity and sound speed range compared to the diagonal arrangement

• transverse flow effects are compensated because the beam crosses the pipe in 2 directions

• higher accuracy of measurement because the accuracy increases with the number of sound paths

Diagonal arrangement with 2 beams Reflection arrangement with 2 beams and 2 planes

• same characteristics as reflection arrangement with 2 beams

• additional characteristic:influences of the flow profile are compensated because the measurement takes place in 2 planes

• same characteristics as diagonal arrangement with 1 beam

• additional characteristic:transverse flow effects are compensated because the measurement is conducted with 2 beams

X arrangement

displacedX arrangement

20 UMFLUXUSF721BV1-1EN, 2017-01-23


If the measuring point is situated near an elbow, the following measurement arrangements are recommended for the se-lection of the sound beam plane.

With vertical pipe orientation With horizontal pipe

• The sound beam plane (see user manual - Advanced Functions, section 2.2.1) has an angle of 90° to the elbow plane. The elbow is upstream of the measuring point.

• The sound beam plane (see user manual - Advanced Functions, section 2.2.1) has an angle of 90° ± 45° to the elbow plane. The elbow is upstream of the measuring point.

With measurements in both directions With measurements in the reflection arrangement with 2 beams and -2 planes

• The sound beam plane (see user manual - Advanced Functions, section 2.2.1) is selected according to the nearest elbow (horizontal or vertical, depending on the pipe orientation - see above).

• The 2 sound beam planes (see user manual - Advanced Functions, section 2.2.1) have an angle of 45° to the el-bow plane. The elbow is upstream of the measuring point.

• With horizontal pipes, the transducers are mounted on the upper half of the pipe.

Step 3: Installation of the Transducers in Variofix C

• Put coupling foil (or some coupling compound for a short-term installation) on the contact surface of the transducers. The coupling foil can be fixed to the contact surface with a small amount of the coupling compound.

• Position the transducers on the rail in such way that the engravings on the transducers form an arrow. The transducer cables show in opposite directions (see Fig. 5.50).

• Adjust the transducer distance displayed by the transmitter (see section 8.3 and Fig. 5.50).

• Slide the spring clips on the transducers (see Fig. 5.51).

• Fix the transducers by tightening the tensioning screws slightly. The end of the screw has to be placed above the hole in the transducer (see Fig. 5.50).

• Correct the transducer distance, if necessary (see section 8.3).

• Tighten the tensioning screw.

• Fix the spacing element on the rail to mark the transducer position (see Fig. 5.50).

• Use a cable tie to fix the transducer cables in order to protect them from mechanical strain (see Fig. 5.51).

• Put the cover on the rail (see Fig. 5.52).

• Tighten the screws on both sides of the cover.


Note! If coupling foil is used: If the signal is not sufficient for the measurement, use the coupling compound instead of the coupling foil.

5.3 Temperature Probes

5.3.1 Preparation of the Pipe

The pipe has to be stable. It has to be able to withstand the pressure exerted by the mounting fixture of the temperature probe.

Rust, paint or other deposits on the pipe isolate the temperature at the measuring point. A good thermal contact between pipe and temperature probe is obtained as follows:

• Clean the pipe at the selected measuring point:

– Remove any insulation material, rust or loose paint.

– If present, the paint layer has to be smoothed by sanding. The paint does not need to be removed completely.

• Use thermal conductivity foil or apply a layer of thermal conductivity paste or coupling compound to the contact surface of the temperature probe. Observe the corresponding operating temperature range.

• Observe that there must be no air pockets between the contact surface of the temperature probe and the pipe wall.

For the installation of the temperature probe (response time 50 s), see section 5.3.2.

For the installation of the temperature probe (response time 8 s), see section 5.3.3.

6.1.4.2 With Potential Separation

If earthing on the same potential cannot be ensured e.g., in measurement arrangements with long extension cables, ex-tension cables and junctions boxes have to be insulated from each other. The junction box and the transducers have to be on the same potential. Thus, no transient currents can enter the transmitter via the extension cable.

• Remove the blind plug for the connection of the extension cable (see Fig. 6.14).


• Push the extension cable through the cap nut, the compression part and the basic part of the cable gland.



• Cut the outer shield and brush it back.

• Pull the extension cable back until the brushed back external shield is below the shield terminal (see Fig. 6.14). The ex-tension cable must remain completely insulated up to the shield terminal.



• Fix the extension cable and the external shield to the shield terminal.


Note! For the installation of transducers to pipes with a cathodic corrosion protection see document TI-FLUXUS_GalvSep.


Fig. 6.14: Connection of the extension cable and the transducer cable to the junction box JBxx (example with JB01)

Attention! The external shield of the extension cable must not have electrical contact to the junction box. There-fore, the extension cable must remain completely insulated up to the shield terminal.

FLUXUS F721 11 Troubleshooting

11 TroubleshootingIf any problem appears which cannot be solved with the help of this user manual, contact our sales office and give a pre-cise description of the problem. Specify the type, the serial number and the firmware version of the transmitter.

Calibration

FLUXUS is a very reliable instrument. It is manufactured under strict quality control using modern production techniques. If installed as recommended in an appropriate location, used cautiously and taken care of conscientiously, no troubles should appear. The transmitter has been calibrated at the factory and, usually, a re-calibration of the transmitter will not be necessary. A re-calibration is recommended if

• the contact surface of the transducers shows visible wear or

• the transducers were used for a prolonged period of time at a high temperature (several months >130 °C for normal transducers or > 200 °C for high temperature transducers).

In order to realize a recalibration under reference conditions either the transmitter, the transducers or the transmitter with transducers have to be sent to FLEXIM depending on which part needs to be calibrated.

The display does not work at all or fails regularly

Check the contrast setting of the transmitter (see user manual – Advanced Functions, section 9.6) or enter the HotCode 555000 to reset the display to medium contrast (see user manual - Advanced Functions, section 9.7).

Make sure that the correct voltage is available at the terminals. The destined voltage is indicated on the metal plate below the outer right terminal.

If the power supply is ok, the transducers or an internal component of the transmitter are defective. The transducers and the transmitter have to be sent to FLEXIM for repair.

If the transmitter is connected only via USB interface, the backlight will be switched off.

An error is displayed in the status line (symbol )

Press key to return to the main menu. Select Spec. functions\System settings\Event log. Press ENTER. The list with error messages is displayed.

Date and time are wrong

The data backup battery has to be replaced. Send the transmitter to FLEXIM.

An output does not work

Make sure that the outputs are configured correctly. Check the function of the output as described in section 8.2.5. If the output is defective, contact FLEXIM.

A measurement is impossible or the measured values substantially differ from the expected values

See section 11.1.

The values of the totalizers are wrong

See section 11.6.

11.1 Problems with the Measurement

A measurement is impossible because no signal is received. A question mark is displayed behind the physical quantity. The LED lights red after the start of the measurement.

• Check if the entered parameters are correct, especially the outer pipe diameter, the pipe wall thickness and the sound speed of the fluid. (typical errors: The circumference or the radius was entered instead of the diameter. The inner pipe di-ameter was entered instead of the outer pipe diameter.)

• Make sure that the recommended transducer distance was adjusted when mounting the transducers.

• Make sure that an appropriate measuring point is selected (see section 11.2) and the number of sound paths has been entered correctly (see section 8.3).

• Try to establish better acoustic contact between the pipe and the transducers (see section 11.3).

• Enter a lower value for the number of sound paths. The signal attenuation might be too high due to a high fluid viscosity or deposits on the inner pipe wall (see section 11.4).

11 Troubleshooting FLUXUS F721

The measuring signal is received but no measured values can be obtained

• If the defined upper or lower limit of the flow velocity is exceeded or is below, Undef and an exclamation mark "!" be-hind the physical quantity will be displayed. The measured values are marked as invalid. The limit has to be adapted to the measuring conditions (see user manual – Advanced Functions, section 4.2).

• If no exclamation mark "!" is displayed, a measurement at the selected measuring point is not possible.

Loss of signal during the measurement

• If the pipe had been run empty: Was there no measuring signal afterwards? Contact FLEXIM.

• Wait briefly until acoustic contact is reestablished. The measurement can be interrupted by a temporarily higher propor-tion of gas bubbles and solids in the fluid.

The measured values substantially differ from the expected values

• Wrong measured values are often caused by wrong parameters. Make sure that the entered parameters are correct for the measuring point.

• If the parameters are correct, see section 11.5 for the description of typical situations in which wrong measured values are obtained.

11.2 Selection of the Measuring Point• Make sure that the recommended min. distance to any disturbance source is observed (see user manual - Advanced

Functions, section 4.2).

• Avoid measuring points with deposit formation in the pipe.

• Avoid measuring points in the vicinity of deformations and defects on the pipe and in the vicinity of welds.

• Make sure that the pipe surface at the selected measuring point is even. The pipe may not be corrugated.

• Measure the temperature at the measuring point and make sure that the transducers are suitable for this temperature.

• Make sure that the outer pipe diameter is within the measuring range of the transducers.

• When measuring on a horizontal pipe, the transducers have to be mounted on the side of the pipes.

• A vertical pipe always has to be filled at the measuring point and the fluid should flow upward.

• No gas bubbles should form (even bubble-free fluids can form gas bubbles when the fluid expands, e.g., upstream of pumps and downstream of great cross-section enlargements).

11.3 Maximum Acoustic ContactObserve the instructions in section 5.2.2.

11.4 Application Specific Problems

A fluid with a wrong sound speed was selected

If a fluid was selected whose sound speed does not fit the sound speed of the fluid in the pipe, it is possible that the trans-ducer distance is not determined correctly.

The sound speed of the fluid is used to calculate the transducer distance and is; therefore, very important for the transduc-er positioning. The sound speeds stored in the transmitter are only used as reference value.

The entered pipe roughness is not appropriate

Check the entered value. The state of the pipe should be taken into account.

Measurements on porous pipe materials (e.g., concrete or cast iron) are only possible under certain conditions

Contact FLEXIM.

The pipe lining may cause problems during the measurement if it is not firmly attached to the inner pipe wall or consists of an acoustically absorbing material

Try measuring on a liner free section of the pipe.

Note! If the temperature fluctuates at the measuring point, it is especially important that the inner hooks of the clasp engage in the tension strap. Otherwise, the contact pressure of the transducers will be in-sufficient at low temperatures.

Note! If the temperature fluctuates widely, it is recommended to use FLEXIM clasps with springs to fix the transducers. Contact FLEXIM.

UMFLUXUSF721BV1-1EN, 2017-01-23 93

FLUXUS F721 11 Troubleshooting

Highly viscous fluids strongly attenuate the ultrasonic signal

Measurements on fluids with a viscosity > 1000 mm²/s are only possible under certain conditions.

A higher proportion of gasor solids in the fluid scatter and absorb the ultrasonic signal and therefore attenuate the measuring signal

A measurement is impossible if the value is ≥ 10 %. If the proportion is high, but < 10 %, a measurement is only possible under certain conditions.

11.5 Large Deviations of the Measured Values

A fluid with a wrong sound speed was selected

If a fluid is selected whose sound speed does not fit the sound speed of the fluid in the pipe it is possible that the measur-ing signal is being mistaken for a pipe wall signal.

The flow calculated on the basis of the wrong signal by the transmitter is very small or fluctuates around zero.

There is gas in the pipe

If there is gas in the pipe, the measured flow will always be too high because both the gas volume and the liquid volume are measured.

The defined upper limit of the flow velocity is too low

All measured flow velocities that are greater than the upper limit will be ignored and marked as invalid. All quantities de-rived from the flow velocity will also be marked as invalid. If several correct measured values are ignored, the totalizer val-ues will be too low.

The entered cut-off flow is too high

All flow velocities below the cut-off flow are set to zero. All derived quantities are also set to zero. The cut-off flow (default 2.5 cm/s) has to be set to a low value to be able to measure at low flow velocities.

The entered pipe roughness is not appropriate

The flow velocity of the fluid is outside the measuring range of the transmitter

The measuring point is not appropriate

Select another measuring point to check whether the results are better. Because pipes are never rotationally symmetric, the flow profile is affected. Change the transducer position according to the pipe deformation.

11.6 Problems with the Totalizers

The values of the totalizers are too small

One of the totalizers has reached the upper limit and has to be reset to zero manually.

The sum of the totalizers is not correct

The sum of both totalizers (throughput Q) is not valid after the overflow of one of the totalizers. (see user manual - Ad-vanced Functions, section 8.1.3).

Behind the value of the totalizer a question mark "?" is displayed

The measurement was temporarily impossible, therefore the value of the totalizer can be wrong.

11.7 Problems During the Heat Flow Measurement

The measured temperature values differ from the actual values.

The temperature probes are not sufficiently insulated.

On a pipe with a small pipe diameter, the temperature probe is lifted from the pipe surface by the insulation foam.

The measured absolute value of the heat flow is correct but has the opposite sign.

Check the assignment of the supply and return temperature to the temperature inputs (see user manual – Advanced Functions, chapter 7).

The calculated heat flow differs from the actual heat flow although the measured flow and temperature values are correct

Check the heat flow coefficient of the fluid (see user manual – Advanced Functions, section 7.2).
