FLUXUS WD 3.1 Measurement principle

3 General principles

In the ultrasonic flow measurement, the flow velocity of the fluid in a pipe is determined. Further physical quantities are derived from the flow velocity and from additional physical quantities, if necessary.

3.1 Measurement principle

The flow velocity of the fluid is measured in the TransitTime mode using the ultrasonic-transit time difference correlation principle. When measuring with a high proportion of gas or solid particles, the transmitter can toggle into the NoiseTrek mode.

3.1.1 Terms

Flow profile

Distribution of flow velocities over the cross-sectional pipe area. For an optimal measurement, the flow profile has to be fully developed and axisymmetrical. The shape of the flow profile depends on whether the flow is laminar or turbulent and is influenced by the conditions at the inlet of the measuring point.

Reynolds number Re

Coefficient describing the turbulence behavior of a fluid in the pipe. The Reynolds number Re is calculated from the flow velocity, the kinematic viscosity of the fluid and the inner pipe diameter.

If the Reynolds number exceeds a critical value (usually approx. 2300, if the fluid flows in a pipe), a transition from a laminar flow to a turbulent flow takes place.

Laminar flow

A flow without any turbulence. There is no mixing between the parallel flowing layers of the fluid.

Turbulent flow

A flow with turbulences (swirling of the fluid). In technical applications, the flow in the pipe is mostly turbulent.

Transition range

The flow is partly laminar and partly turbulent.

Sound speed c

Speed of the propagating sound. The sound speed depends on the mechanical properties of the fluid or the pipe material. In pipe materials and other solid materials, a distinction is made between the longitudinal and transversal sound speed. For the sound speed of some fluids and materials, see annex C.

Flow velocity v

Average value of all flow velocities of the fluid over the cross-sectional pipe area.

Acoustic calibration factor k

ka =

The acoustic calibration factor k

is a transducer parameter which results from the sound speed c within the transducer

and the angle of incidence. According to Snell's law of refraction, the angle of propagation in the adjoining fluid or pipe material is:

= = =

Fluid mechanics correction factor k

With the fluid mechanics calibration factor kRe, the measured value of the flow velocity in the area of the sound beam is converted into the value of the flow velocity across the whole cross-sectional pipe area. In case of a fully developed flow profile, the fluid mechanics calibration factor only depends on the Reynolds number and the roughness of the inner pipe wall. The fluid mechanics calibration factor is recalculated by the transmitter for each new measurement.

Volumetric flow rate

= v · A

The volume of the fluid that passes through the pipe per unit time. The volumetric flow rate is calculated from the product of the flow velocity v and the cross-sectional pipe area A.

Mass flow rate

= · 

The mass of the fluid that passes through the pipe per unit time. The mass flow rate is calculated from the product of the volumetric flow rate and the density .

3.1 Measurement principle FLUXUS WD

3.1.2 Measurement of the flow velocity in the TransitTime mode

The signals are emitted and received by 2 transducers alternatively in and against the flow direction. If the fluid is flowing, the signals propagating in the fluid are displaced with the flow.

Caused by this displacement, the sound path of the signal in flow direction is reduced and the signal against the flow direction is increased, see Fig. 3.1 and Fig. 3.2.

This causes a change in the transit times. The transit time of the signal in flow direction is shorter than the transit time against the flow direction. The transit time difference is proportional to the average flow velocity.

The average flow velocity of the fluid is calculated as follows:

· ka ·

v = k

where

v – average flow velocity of the fluid

– fluid mechanics calibration factor

– acoustic calibration factor

t – transit time difference

3.1.3 Measurement of the flow velocity in the NoiseTrek mode

If the proportion of gas or solids in the fluid is high, the damping of the ultrasonic signal can be so high that the complete propagation of the fluid and therefore a measurement in TransitTime mode is not possible anymore. In this case the NoiseTrek mode has to be used.

The NoiseTrek mode uses the presence of gas bubbles and/or solid particles in the fluid.

Ultrasonic signals are sent from a transducer into the fluid at short intervals, reflected by the gas bubbles and/or the solids particles and again received by the same transducer.

The measurement arrangement used in the TransitTime mode does not need to be changed.

The transit time difference t of 2 consecutive ultrasonic signals is determined. It behaves proportionately to the distance the gas bubble/solid particle is covering between 2 consecutive pulses and thus, to the average flow velocity of the fluid, see Fig. 3.4.

Fig. 3.4: Measurement of the flow velocity in the NoiseTrek mode

The average flow velocity of the fluid is calculated as follows:

Depending on the attenuation of the ultrasonic signal, the error of measurement in the NoiseTrek mode can be greater than in the TransitTime mode.

3.2 Measurement arrangements FLUXUS WD

3.1.4 Measurement of the flow velocity in the HybridTrek mode

The HybridTrek mode combines the TransitTime and the NoiseTrek mode. During a measurement in the HybridTrek mode, the transmitter automatically toggles between the TransitTime and the NoiseTrek mode depending on the gaseous or solid content.

The measurement arrangement is identical to the one in the TransitTime mode.

3.2 Measurement arrangements

3.2.1 Terms

Diagonal arrangement Reflection arrangement

The transducers are mounted on opposite sides of the pipe. The transducers are mounted on the same side of the pipe.

Sound path

The distance covered by the ultrasonic signal after crossing the pipe once. The number of the sound paths is:

• odd if the measurement is carried out in diagonal arrangement

• even if the measurement is carried out in reflection arrangement

Beam

The path covered by the ultrasonic signal between the transducers, i.e., the transducer emitting the ultrasonic signal and the transducer receiving it. One beam consists of 1 or several sound paths.

3.3 Acoustic penetration

The pipe has to be acoustically penetrable at the measuring point. The acoustic penetration is given when pipe and fluid do not attenuate the sound signal so strongly that it is completely absorbed before reaching the second transducer.

The attenuation caused by the pipe and the fluid depends on:

• kinematic viscosity of the fluid

• proportion of gas bubbles and solids in the fluid

• deposits on the inner pipe wall

• pipe material

The following requirements have to be met at the measuring point:

• the pipe is always completely filled

• no solid deposits in the pipe

• no bubble formation in the pipe

Even bubble-free fluids can form gas bubbles when the fluid expands, e.g., before pumps and after great cross-section extensions.

3 General principles

FLUXUS WD 3.4 Undisturbed flow profile

Observe the following notes on the selection of the measuring point:

Horizontal pipe

Select a measuring point where the transducers can be mounted laterally on the pipe, allowing the sound waves to propagate horizontally in the pipe. Thus, solids on the bottom of the pipe or gas bubbles in the pipe's upper part are prevented from influencing the propagation of the signal, see Fig. 3.9 and Fig. 3.10.

Vertical pipe

Select the measuring point at a pipe location where the fluid flows upward. The pipe has to be completely filled, see Fig.

3.11 and Fig. 3.12.

3.4 Undisturbed flow profile

Some flow elements (e.g., elbows, valves, pumps, reducers) distort the flow profile in their vicinity. The axisymmetrical flow profile in the pipe needed for correct measurement is no longer given. A careful selection of the measuring point helps to reduce the impact of disturbance sources.

It is most important that the measuring point is chosen at a sufficient distance from any disturbance sources. Only then it can be assumed that the flow profile in the pipe is fully developed. However, measuring results can be obtained even if the recommended distance to disturbance sources cannot be met for practical reasons.

The recommended straight inlet and outlet pipe lengths for different types of flow disturbance sources are shown in the examples in Tab. 3.1.

6.2 Transducers

6.2.1 Preparation

6.2.1.1 Measuring point selection

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

• the flow profile is fully developed

The correct selection of the measuring point and the correct transducer positioning guarantee 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 solution 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 distorted or defective areas of the pipe or in the vicinity of welds.

• Avoid measuring points with deposit formation in the pipe.

• Make sure the pipe surface at the selected measuring point is even.

• Select the location of the transmitter within the transducer cable range.

• The ambient temperature at the measuring point has to be within the operating temperature range of the transmitter and the transducers, see Technical specification.

If the measuring point is within an explosive atmosphere, possibly present danger zones and gases have to be determined. The transducers and the transmitter have to be appropriate for these conditions.

6.2.1.2 Pipe preparation

Contact with grinding dust

This may result in injuries (e.g., breathing difficulties, skin reactions, eye irritations).  Wear the required personal protective equipment. Observe the applicable rules.

The pipe has to be sufficiently stable to withstand the pressure exerted by the transducers and the tension straps.

Observe the selection criteria of pipe and measuring point.

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

• Clean the pipe at the selected measuring point.

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

– Remove 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 transducers.

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

• use in the presence of deposits on the inner pipe wall or with strongly attenuating gases or liquids (only 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

FLUXUS WD 6.2 Transducers

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

Vertical pipes Horizontal pipes

• The sound beam plan is selected in an angle of 90° to the elbow plane. The elbow is upstream of the measuring point.

• The sound beam plane is selected in an angle of 90° ± 45° to the elbow plane. The elbow is upstream of the measuring point.

Bidirectional measurements Measurements in reflection

arrangement with 2 beams and 2 planes

• The sound beam plane is selected according to the nearest elbow (horizontal or vertical, depending on the pipe orientation, see above).

• The 2 sound beam planes are selected in an angle of 45° to the elbow plane. The elbow is upstream of the measuring point.

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

FLUXUS WD 7.1 Transducers

7.1 Transducers

It is recommended to run the cables from the measuring point to the transmitter before connecting the transducers to avoid load on the connectors.

If transducers are replaced or added, the sensor module also has to be replaced or added, see section 7.1.5.

Fig. 7.1: Connection of the transducers to the transmitter

1 – transducers (measuring channel A) 2 – transducers (measuring channel B)

7.1.1 Connection of the transducer cable to the transmitter

The degree of protection of the transmitter is only ensured if all cables are tightly fitted using cable glands and the housing is firmly screwed.

• Remove the blind plug for the connection of the transducer cable.

• Open the cable gland of the transducer cable. The compression part remains in the cap nut.

• Push the transducer cable through the cap nut and the compression part.

• Prepare the transducer cable.

• Shorten the external shield and brush it back over the compression part.

• Screw the sealing ring side of the basic part into the transmitter housing.

• Insert the transducer cable into the housing.

For good electromagnetic compatibility (EMC), it is important to ensure good electrical contact between the external shield and the cap nut (and thus the housing).

• Fix the cable gland by screwing the cap nut onto the basic part.

• Connect the leads of the transducer cable to the terminals of the transmitter, see Fig. 7.2 and Tab. 7.1.

7.1 Transducers FLUXUS WD

7.1.4.2 Connection with potential separatio n

If earthing on the same potential cannot be ensured e.g., in measurement arrangements with long extension cables, the extension cable and the junction box have to be electrically insulated from each other. The junction box and the transducers have to be on the same potential. By doing this, no compensation currents can flow to the transmitter via the extension cables.

For measurement arrangements where the junction box and the transducers have to be electrically insulated from each other, see the document TIFLUXUS_GalvSep.

• Remove the blind plug for the connection of the extension cable.

• Open the cable gland of the extension cable. The compression part remains in the cap nut.

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

• Insert the extension cable into the junction box.

• Prepare the extension cable.

• Cut the outer shield and brush it back.

• Pull the extension cable back until the back brushed external shield is below the shield terminal, see Fig. 7.6. The extension cable has to remain completely insulated up to the shield terminal.

• Screw the gasket ring side of the basic part into the junction box.

• Fix the cable gland by screwing the cap nut onto the basic part.

Observe the max. permissible voltage of 60 V DC between the earth potentials.

The external shield of the extension cable must not have electrical contact to the junction box. Therefore, the extension cable has to remain completely insulated up to the shield terminal.

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

• Connect the extension cable to the terminals of the junction box, see Fig. 7.6 and Tab. 7.5.

7.1.5 Transducer module (SENSPROM)

The transducer module contains important transducer data for the operation of the transmitter with transducers.

If transducers are replaced or added, the sensor module must also be replaced or added.

The serial numbers of the transducer module and the transducer must be identical. A wrong or incorrectly connected sensor module will lead to incorrect measured values or to a measurement failure.

The sensor module is connected to the terminals of the transmitter, see Fig. 7.7.

• Disconnect the transmitter from the power supply.

• Connect the transducer module to the corresponding terminal, see Fig. 7.7. Terminal X2 is assigned to the transducers of measuring channel A, terminal X3 to the transducers of measuring channel B.

• Connect the transmitter to the power supply.

• Enter all parameters of the program branch Parameters.

• Start the measurement.

7 Connection

7.2 Power supply

The installation of the power supply is carried out by the operator. The operator has to provide an overcurrent protector (fuse or similar device) disconnecting all energizing wires in case of an inadmissible high current consumption. The impedance of the protective earth has to be low ohmic in order not to allow touch voltage pass the permissible limit. The equipotential bonding terminal serves as functional earth of the transmitter, see Fig. 7.8.

The degree of protection of the transmitter will only be guaranteed if the power cable fits firmly and tightly in the cable gland.

Fig. 7.8: Equipotential bonding terminal on the transmitter

1 – equipotential bonding terminal on stainless steel housing 2 – equipotential bonding terminal on aluminum housing

• Connect the power cable to the transmitter.

For the connection of the power supply cable to the transmitter, see section 7.2.1, Fig. 7.9 and Tab. 7.6.

If any problem appears which cannot be solved with the help of this operating instruction, contact our sales office and give a precise description of the problem. Specify the type, the serial number and the firmware version of the transmitter.

Calibration

If installed as recommended in an appropriate location, used cautiously and serviced conscientiously, no troubles should appear.

The transmitter has been calibrated at factory and, usually, a re-calibration of the transmitter is not necessary.

A re-calibration is recommended if:

• the contact surface of the transducers show visible wear or

• the transducers were used for a prolonged period at high temperatures (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.

FLUXUS WD 10.1 Problems with the measurement

The display does not work at all or fails regularly

Check the contrast setting of the transmitter or enter the HotCode 555000 to set the display to medium contrast.

Make sure that the correct voltage is available at the terminals. The destined transmitter voltage is indicated on the nameplate 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 only connected via the USB interface, the backlight will be switched off.

An error is displayed in the status indication (symbol )

Press key to return to the main menu. Select Special functions\System settings\Event log. Press ENTER. The error message list will be displayed.

Date and time are wrong, the measured values are deleted when the transmitter is switched off

The data backup battery has to be replaced if the date and the time are reset or wrong or the measured values are deleted after the transmitter has been switched off and on. Send the transmitter to FLEXIM.

An output does not work

Make sure that the outputs are configured correctly. Check the function of the output. If the output is defective, contact FLEXIM.

10.1 Problems with the measurement

A measurement is not possible because no signal is received. A question mark is displayed after the physical quantity. The LED lights red after starting the measurement.

• Check whether 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 diameter was entered instead of the outer pipe diameter.

• Check the number of sound paths.

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

• Make sure that an appropriate measuring point is selected and the number of sound paths was entered correctly.

• Try to establish a better acoustic contact between the pipe and the transducers.

• 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.

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 below, UNDEF and an exclamation point will be displayed after the physical quantity. The measured values are marked as invalid. The limit has to be adapted to the measuring conditions.

• If no exclamation point is displayed, a measurement at the selected measuring point is impossible.

Signal loss during the measurement

• If there is no measuring signal after the pipe had been run empty and refilled, contact FLEXIM.

• Wait a moment until the acoustic contact is reestablished. The measurement can be interrupted due to a temporarily higher proportion 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.

10 Troubleshooting

10.2 Measuring point selection FLUXUS WD

10.2 Measuring point selection

• Make sure that the recommended min. distance to any disturbance source is observed.

• Avoid measuring points with deposit formation in the pipe.

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

• Make sure the pipe surface at the selected measuring point is even.

• 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 laterally on the pipe.

• The measuring point on a vertically mounted pipe has always to be filled. 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).

10.3 Maximum acoustic contact

see section 6.2

10.4 Application-specific problems

A fluid with a wrong sound speed was selected

If the selected sound speed in the fluid does not match the actual one, the transducer distance can probably not be determined correctly.

The fluid sound speed is used to calculate the transducer distance and is therefore very important for the transducer positioning. The sound speeds stored in the transmitter only serve as an orientation.

The entered pipe roughness is not appropriate

Check the entered value. The pipe state should be considered.

Measurements on pipes made of porous materials (e.g ., concrete or cast iron) are only conditionally possible

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 acoustically absorbing material

Try to measure on a section of the pipe free from lining.

Highly viscous fluids strongly attenuate the ultrasonic signal

The measurement of fluids with a viscosity of > 1 000 mm²/s is only conditionally possible.

A high concentration of gases or solids in the fluid scatter and absorb the ultrasonic signal and thus attenuate the measuring signal

A measurement is impossible if the value is  10 %. If the proportion is high, but < 10 %, a measurement is only conditionally possible.

10.5 Significant deviations of the measured values

A fluid with a wrong sound speed was selected

If a fluid was selected whose sound speed does not match the actual one, the measuring signal may be confused with the 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 be too high because both, the liquid and gas 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 deviated from the flow velocity will also be indicated as invalid. If several correct measured values are ignored, the totalizer values 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 has to be set to a low value to be able to measure at low flow velocities (default: 2.5 cm/s).

Page 97

10 Troubleshooting

FLUXUS WD 10.6 Problems with the totalizers

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

Check whether a different measuring point provides better results. Because pipes are never rotationally symmetric, the flow profile is affected.

10.6 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 output sum of both totalizers (throughput Q) transmitted via an output is not valid after one of the totalizers has overflowed for the first time.

A question mark is displayed after the value of the totalizer

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