3 General principles

FLUXUS F60* 3.1 Measurement principle

UMFLUXUS_F60xV5-0EN, 2017-10-16

3 General principles

For the ultrasonic measurement of the flow rate, 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.

Page 14

2017-10-16, UMFLUXUSF60xV5-0EN

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 correction 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 correction factor only depends on the Reynolds number and the roughness of the inner pipe wall. The fluid mechanics correction factor is recalculated by the transmitter for each new measurement.

Mass flow rate

= · ρ

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 ρ.

Transit time difference ∆t

Is the transit time difference of the signals. In the TransitTime principle, the transit time difference of the signals in and against the flow direction is measured, in the NoiseTrek mode, the time difference of the signal from the transducer to the particle and vice versa. The flow velocity of the fluid flowing in the pipe is determined from the transit time difference.

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.

Heat flow

The heat quantity that is transferred per unit time. For the calculation of the heat flow see chapter 21.

UMFLUXUS_F60xV5-0EN, 2017-10-16

3.1.2 Measurement of the flow velocity in the TransitTime mode

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

This displacement causes a reduction in distance for the signal in flow direction and an increase in distance for the signal against the flow direction of the receiving transducer, 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. This transit time difference is proportional to the average flow velocity.

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

v = k

· ka ·

where

v – average flow velocity of the fluid

– fluid mechanics correction factor

– acoustic calibration factor

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 solids in the fluids.

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 setup used in the TransitTime mode does not need to be changed.

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

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

v=k

Re·ka

where

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

3.1.4 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 setup is the same as the one in the TransitTime mode.

3.1.5 Measurement of the flow velocity in the NoiseTrek parallel beam

mode

Pipes with a small pipe diameter or fluids which strongly attenuate the ultrasonic signal can cause a reduction of the transit time in the fluid with the result that the signal quality is no longer sufficient. In this case the NoiseTrek parallel beam mode has to be used.

The NoiseTrek parallel beam mode works the same way the NoiseTrek mode does, the only difference is that the sending and receiving process do not occur in the same transducer. This leads to a better signal quality. The transducers are mounted in parallel on the pipe at a small angle, see Fig. 3.5.

This measurement arrangement cannot be used in the TransitTime mode.

3.3 Acoustic penetration FLUXUS F60*

2017-10-16, UMFLUXUSF60xV5-0EN

3.3 Acoustic penetration

The pipe has to be acoustically penetrable at the measuring point. The acoustic penetration is reached 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

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. 3.10 and Fig. 3.11.

Notice!

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

3.4 Undisturbed flow profile FLUXUS F60*

2017-10-16, UMFLUXUSF60xV5-0EN

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.

6.2.1 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.

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.

6.2.1.3 Selection of the measurement arrangement

Notice!

Observe the selection criteria for the pipe and the measuring point.

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 (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

9.2.1 Selection of the physical quantity and the unit of measurement

The following physical quantities can be measured:

• sound speed

• flow velocity: is calculated on the basis of the measured transit time difference

• volumetric flow rate: is calculated by multiplying the flow velocity by the cross-sectional pipe area

• mass flow rate: is calculated by multiplying the volumetric flow rate by the operating density of the fluid

• heat flow: is calculated from the volumetric flow rate, the measured temperatures of the supply and return lines, and the heat flow coefficients of the fluid

The physical quantity is selected as follows:

• Select the program branch Output Options.

• Press ENTER.

• Select the channel for which the physical quantity is to be entered (here: channel A).

• Press ENTER.

• Select the physical quantity in the scroll list.

For the selected physical quantity (except for the sound speed), a scroll list with the available units of measurement is displayed. The unit of measurement which was selected previously is displayed first.

• Select the unit of measurement of the selected physical quantity.

• Press ENTER.

9.2.2 Input of the damping factor

Each displayed measured value is a floating average of all measured values of the last x seconds, with x being the damping factor. A damping factor of 1 s means that the measured values are not averaged because the measuring rate is approx 1/s. The default value of 10 s is appropriate for normal flow conditions. Values which fluctuate strongly due to a higher flow dynamic, require a higher damping factor.

• Select the program branch Output Options.

• Press ENTER until the menu item Damping is displayed.

• Enter the damping factor.

• Press ENTER.

Press key BRK to return to the main menu. The further displays of the program branch

Output Options are used for the activation of the measured value transmission.
