KATflow 230 2 Introduction
2 Introduction
The KATflow 230 is a portable, battery operated ultrasonic flowmeter utilising
clamp-on sensors for the measurement of liquids in full closed pipes. Flow measurements can be undertaken without interrupting of the process or interfering with
the integrity of the pipeline. The clamp-on sensors are simply attached to the outside of pipes. The KATflow 230 uses ultrasonic signals for the measurement of the
flow, employing the so-called transit-time method.
Ultrasonic signals are emitted by a first transducer installed on one side of a pipe,
reflected on the opposite side and received by a second transducer. These signals
are emitted alternatively in the direction of flow and against it. Because the medium
in which the signals propagate is flowing, the transit time of the sound signals
propagating in the direction of flow is shorter than the transit time of the signal
propagating against the direction of flow. The transit-time difference ∆T is measured and allows the determination of the average flow velocity along the path of
acoustic propagation. A profile correction is then performed to obtain the average
flow velocity over the cross-sectional area of the pipe, which is proportional to the
volumetric flow rate.

Care should be taken when opening the box containing the flowmeter, any markings or warnings shown on the parcel should be observed prior to opening. The following steps should then be taken:
● Unpack the flowmeter in a dry area.
● The flowmeter should be handled with care and not left in an area where it
could be subject to physical shocks.
● If using a knife to remove packaging care should be taken not to damage
the flowmeter or cables.
● The flowmeter package and contents should be checked for completeness
against the delivery note supplied and any missing items reported immediately.
● The flowmeter package and contents should be checked for signs of dam-
age during transport and any problems reported immediately.
● The vendor accepts no responsibility for damage or injury caused during
the unpacking of the instrumentation supplied.
● Excess packing materials should be either re-cycled or disposed of in a
suitable way.
3.1.2 Storage and preservation

KATflow 230 3 Installation
3.2 Clamp-on sensor installation
The correct selection of the sensor location is crucial for achieving reliable measurements and a high accuracy. Measurement must take place on a pipe in which
sound can propagate (see Acoustic Propagation) and in which a rotationally symmetrical flow profile is fully developed (see Straight Pipe Lengths).
The correct positioning of the transducers is an essential condition for error-free
measurements. It guarantees that the sound signal will be received under optimal
conditions and evaluated correctly. Because of the variety of applications and the
different factors influencing the measurement, there can be no standard solution for
the positioning of the transducers.
The correct position of the transducers will be influenced by the following factors:
● diameter, material, lining, wall thickness and general condition of the pipe,
● the medium flowing in the pipe,
● and the presence of gas bubbles and solid particles in the medium.
Check that the temperature at the selected location is within the operating temperature range of the transducers (see technical specification in the Appendix).
Acoustic propagation is given when the flowmeter is able to receive sufficient signal
from the transmitted ultrasonic pulses. The signals are attenuated in the pipe material, the medium and at each of the interfaces and reflections. External and internal pipe corrosion, solid particles and gas content in the medium do heavily contribute to signal attenuation.
Sufficient straight lengths of pipe on the inlet and outlet of the measuring location
guarantee an axi-symmetrical flow profile in the pipe for good measurement accuracy. If no sufficient straight lengths of pipe are available for your application, measurements are still obtainable but the uncertainty of the measurement can be compromised.
3.3 Installation location
Select an installation location as per recommendations in Table 1 and try to avoid
measuring
● in the vicinity of deformations and defects of the pipe,
● near welding seams,
● where deposits could be building 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 propagate horizontally in the pipe. Thus, the solid particles deposited on the bottom of the pipe and
the gas pockets developing at the top will not influence the propagation of the signal.
Correct Incorrect
For a free inlet or outlet pipe section:
Select the measuring point at a location where the pipe cannot run empty.

3.4 Pipe preparation
● Clean the pipework from dirt and dust around the area where the sensors
shall be placed.
● Remove loose paint and rust with a wire brush or file.
Firmly bonded paint does not necessarily need to be removed down to bare metal
provided the flowmeter diagnostics indicate sufficient signal level strength.

3.5 Clamp-on sensor mounting configurations and separation
distance
The most common clamp-on sensor mounting configuration is the Reflection Mode,
also known as V-Mode (see Illustration 3, sketch (1). Here the ultrasonic signal
pass twice through the medium (2 signal passes). The Reflection Mode is the most
convenient mounting method as the transducer separation distance can be measured easily and the sensors can be perfectly aligned. This method should be used
whenever possible.
An alternative mounting configuration (Illustration 3, sketch (3)) is the Diagonal
mode (Z-Mode). The signals travel here only once through the pipe. This method
is often used especially for larger pipes where greater signal attenuation might occur.
Further variation of the Reflection and the Diagonal Mode are possible by altering
the number of passes through the pipe. Any even number of passes would require
to mount the sensors on the same side of the pipe, whereas with any odd number
of passes, the sensors must be mounted on opposite sides of the pipe. Commonly
for very small pipes, sensor mounting configurations 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 edges of the sensor
heads facing each other as shown in illustration 3. It is automatically calculated by
the flowmeter based on the parameter entries for pipe outside diameter, wall thickness, lining material and thickness, medium, process temperature, the sensor type
and the selected number of signal passes.
A negative separation distance A < 0 can occur for mounting configurations on
small pipes where diagonal mode operation has been selected (see Illustration 3,
sketch (3).

3.6.2 Electrical interconnections
3.7 Clamp-on sensor mounting
Before the sensors can be mounted
● the installation location should have been determined,
● a sensor mounting method should be chosen,
● the flowmeter batteries must be sufficiently charged,
● the sensors must be connected to the transmitter.
Depending on which sensor mounting method is being used (V or Z-mode), the
clamp on sensors are either mounted on the same side of the pipe (Reflection
Mode) or on opposite sides of the pipe (Diagonal Mode).

3.7.3 Correct positioning of the sensors
Always mount the transducer pair such that the free front edges of the sensors face
each other.
There is a different engraving on the top of each transducer. The transducers are
mounted correctly if the engravings on the two transducers are forming an arrow together. The transducer cables should then show in opposite directions.
Later, the arrow, in conjunction with the indicated measured value, will help to determine 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, lining material
and thickness, medium, process temperature, the sensor type and the selected
number of signal passes.
3.7.4 Sensor mounting with fixtures and chains
● Insert the retaining clip into the groove on the top of the transducer and se-
cure it using the screw knob.
● Apply some acoustic coupling component to the contact surface of the
transducer.
● Place the transducer to the side of the pipe or alternatively 45 degrees from
the pipe axis.
This is necessary to establish the best acoustic contact since on top of the
pipe air pockets could develop and deposits could accumulate at the bottom of the pipe.

KATflow 230 3 Installation
● Take the spring end of the chain in one hand and insert the last ball ele-
ment in the vertical slot of the retaining clip. Mount the chain around the
pipe.
● Pull the chain firmly around the pipe and fasten it in the lateral slot of the
retaining clip. There should be no air pockets between the transducer surface and the pipe wall.
● Mount the second transducer the same way.
● Using a measuring tape, adjust the sensor separation distance as sugges-
ted by the flowmeter.

Ultrasonic Flowmeter
KATflow 230
Description
The KATflow range of non-invasive flowmeters utilises
ultrasonic technology for the accurate flow measurement
of liquids and liquified gases in full pipes.
The KATflow 230 is designed for portable use to meet the
needs of the Service/Maintenance and Commissioning
Engineer wishing to check the flow rate at different
locations in the plant. The set-up of the unit is simple
through a setup wizard in order to obtain the required flow
information in minutes.
The measurement of flow is based on the principle that
sound waves are influenced by a flowing medium.
Measurements are made by penetrating the pipe with
ultrasound and subsequently time differences, frequency
variations and phase shifts of the ultrasonic signals are
evaluated.
The ultrasonic sensors are clamped onto the outside of
the pipe, thus eliminating the need to dismantle the
pipework and interrupt the process. The KATflow 230
can be applied to any type of standard pipe carrying
clean or dirty liquids and liquified gases.
Advantages
• Low installation effort and costs
•
Measurement is independent of fluid conductivity
• No pressure loss, no possibility of leakage
• Retrospective installation for existing plants
possible
• No cutting of pipes necessary, no interruption of
process, no plant shut down
• No additional fittings for maintenance required
• Hygienic measurement, no risk of contamination,
suitable for ultra clean liquids
• No contact with medium, no risk of corrosion when
used with aggressive media
• Cost advantages when used with large diameter
pipes, high pressure systems, etc.
