KATflow 210 2 Introduction
2 Introduction
The KATflow 210 is a portable, battery operated ultrasonic flowmeter employin
clamp-on sensors for the measurement of liquids in full, enclosed pipes. Flow
measurements can be undertaken without interruption of the process or interfer-
ence with the inte rity of the pipeline. The clamp-on sensors are attached to the
outside of the pipes. The KATflow 210 uses ultrasonic si nals for the measure-
ment of the flow, employin the transit-time method.
Ultrasonic si nals are emitted by a transducer installed on a pipe and received by a
second transducer. These si nals are emitted alternately in the direction of flow and
a ainst it. Because the medium is flowin , the transit time of the sound si nals
propa atin in the direction of flow is shorter than the transit time of the si nal
propa atin a ainst the direction of flow. The transit-time difference ΔT is meas-
ured and allows the determination of the avera e flow velocity alon the path of
acoustic propa ation. A profile correction is then performed to obtain the avera e
flow velocity over the cross-sectional area of the pipe, which is proportional to the
volumetric flow rate.

3.2 Clamp-on sensor installation
The correct selection of the sensor location is crucial for achievin reliable meas-
urements and a hi h accuracy. Measurement must take place on a pipe in which
sound can propa ate (see Acoustic Propa ation) and in which a rotationally sym-
metrical flow profile is fully developed (see Strai ht Pipe Len ths).
The correct positionin of the transducers is an essential condition for error-free
measurements. It uarantees that the sound si nal will be received under optimal
conditions and evaluated correctly. Because of the variety of applications and the
different factors influencin the measurement, there can be no standard solution for
the positionin of the transducers.
The correct position of the transducers will be influenced by the followin factors:
●diameter, material, linin , wall thickness and eneral condition of the pipe,
●the medium flowin in the pipe,
●and the presence of as bubbles and solid particles in the medium.
Check that the temperature at the selected location is within the operatin temper-
ature ran e of the transducers (see technical specification in the Appendix).
Acoustic propa ation is iven when the flowmeter is able to receive sufficient si nal
from the transmitted ultrasonic pulses. The si nals are attenuated in the pipe ma-
terial, the medium and at each of the interfaces and reflections. External and in-
ternal pipe corrosion, solid particles and as content in the medium do heavily con-
tribute to si nal attenuation.
Sufficient strai ht len ths of pipe on the inlet and outlet of the measurin location
uarantee an axi-symmetrical flow profile in the pipe for ood measurement accur-
acy. If no sufficient strai ht len ths of pipe are available for your application, meas-
urements are still obtainable but the uncertainty of the measurement can be com-
promised.
3.3 Installation location
Select an installation location followin the recommendations in Table 1 and try to
avoid measurin :
●in the vicinity of deformations and defects of the pipe,
●near weldin seams,
●where deposits could be buildin up in the pipe.
For a horizontal pipe:
Select a location where the transducers can be mounted on the side of the pipe, so that the sound waves emitted by
the transducers propa ate horizontally in the pipe. In this way, the solid particles deposited on the bottom of the pipe
and the as pockets developin at the top will not influence the propa ation of the si nal.

3.4 Pipe preparation
●Clean dirt and dust from around the area of the pipework where the
sensors are to be placed.
●Remove loose paint and rust with a wire brush or file.
Firmly bonded paint does not necessarily need to be removed provided the flow-
meter dia nostics indicate sufficient si nal stren th.
3.5 Clamp-on sensor mounting configurations and separation
distance
The most common clamp-on sensor mountin confi uration is the Reflection Mode,
sometimes known as V-Mode (see Illustration 3, sketch (1). Here, the ultrasonic
si nal passes twice throu h the medium (2 si nal passes). The Reflection Mode is
the most convenient mountin method as the transducer separation distance can
be measured easily and the sensors can be accurately ali ned. This method
should be used whenever possible.
An alternative mountin confi uration (Illustration 3, sketch (3)) is the Dia onal
mode (Z-Mode). The si nals travel only once throu h the pipe. This method is of-
ten used for lar er pipes where reater si nal attenuation mi ht occur.
Further variation of the Reflection and the Dia onal Modes are possible by alterin
the number of passes throu h the pipe. Any even number of passes will require
mountin the sensors on the same side of the pipe, while with an odd number of
passes, the sensors must be mounted on opposite sides of the pipe. Commonly,
for very small pipes, sensor mountin confi urations such as 4 passes (W-mode)
or 3 passes (N-mode) are used (Illustration 3, sketch (2)).
The transducer separation distance A is measured from the inside ed es of the
sensor heads as shown in illustration 3. It is automatically calculated by the flow-
meter based on the parameter entries for pipe outside diameter, wall thickness, lin-
in material and thickness, medium, process temperature, the sensor type and the
selected number of si nal passes.
A ne ative separation distance A < 0 can occur for mountin confi urations on
small pipes where dia onal mode operation has been selected (see Illustration 3,
sketch (3). Ne ative separation distances may be su ested for reflection mode in-
stallations, but are not possible. In these cases, use dia onal mode or a lar er
number of passes.

3.7 Clamp-on sensor mounting
Before the sensors can be mounted
●the installation location should have been determined,
●a sensor mountin method should be chosen,
●the flowmeter batteries must be sufficiently char ed,
●the sensors must be connected to the transmitter.
Dependin on which sensor mountin method is bein used, the clamp on sensors
are either mounted on the same side of the pipe (Reflection Mode) or on opposite
sides of the pipe (Dia onal Mode – See Section 2.5).

3.7.3 Correct positioning of the sensors
Mount the transducer pair so that the front ed es of the sensors (opposite the cable
entry) face each other.
There is a different en ravin on the top of each transducer. The transducers are
mounted correctly if the en ravin s on the two transducers form an arrow. The
transducer cables should point in opposite directions.
Later, the arrow, in conjunction with the indicated measured value, will help to de-
termine the direction of flow.
The sensor separation distance is automatically calculated by the flowmeter based
on the parameter entries for pipe outside diameter, wall thickness, linin material
and thickness, medium, process temperature, the sensor type and the selected
number of si nal passes. The sensor positionin screen (above, and Section 3.3)
allows fine adjustment of the sensor location.
3.7.4 Sensor mounting with fixtures and chains
●Insert the retainin clip into the roove on the top of the transducer and se-
cure it usin the screw knob.
●Apply some acoustic couplin component to the contact surface of the
transducer.
16
Illustrati n 6: C rrect p siti ning f the sens rs
Illustrati n 7: Sens r m unting with clips and chains

KATflow 210 3 Installation
●Place the transducer on the side of the pipe or alternatively up to 45 de-
rees from the horizontal plane throu h the pipe.
This is advisable to establish the best acoustic contact since on top of the
pipe air pockets could develop and deposits could accumulate at the bot-
tom of the pipe.
●Take the sprin end of the chain in one hand and insert the last ball ele-
ment in the vertical slot of the retainin clip. Mount the chain around the
pipe.
●Pull the chain firmly around the pipe and fasten it in the lateral slot of the
retainin clip. There should be no air pockets between the transducer sur-
face and the pipe wall.
●Mount the second transducer the same way.
●Usin a measurin tape, adjust the sensor separation distance as su es-
ted by the flowmeter. When the sensor positionin screen (Section 3.3) is
displayed, the middle bar allows fine adjustment of the sensor location.
