INTRODUCTION
INTRODUCTION
.1 Clamp-on transit-time flowmeter
The KATflow 00 is a hand-held, battery operated ultrasonic flowmeter employing 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 integrity of the pipeline. The clamp-on sensors are attached to the outside of the pipes. The KATflow 00
uses ultrasonic signals for measurement of the flow, employing the transit-time method.

Picture 1: Clamp-on ultrasonic flowmeter configuration
. Measuring principle
Ultrasonic signals are emitted by a transducer installed on a pipe and received by a second transducer. These signals are
emitted alternately in the direction of flow and against it. Because the medium is flowing, the transit time of the sound sig -
nals propagating in the direction of flow is shorter than the transit time of the signal propagating against the direction of
flow. The transit-time dierence ∆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.

INSTALLATION
3. Clamp-on sensor installation
The correct selection of the sensor location is crucial for achieving reliable measurements and high accuracy. Measure-
ment must take place on a pipe in which sound can propagate (see Section 3. .1 Acoustic propagation) and in which a ro-
tationally symmetrical flow profile is fully developed (see Section 3. . Straight pipe lengths).
The correct positioning of the transducers is an essential condition for error-free measurements. It ensures that the sound
signal will be received under optimal conditions and evaluated correctly. Because of the variety of applications and the
dierent 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,
•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 Chapter 9).
3. .1 Acoustic propagation
Acoustic propagation is achieved when the flowmeter is able to receive suicient 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 contribute heavily to signal attenuation.
3. . Straight pipe lengths
Suicient straight lengths of pipe on the inlet and outlet of the measuring location ensure an axi-symmetrical flow profile
in the pipe, which is required for good measurement accuracy. If insuicient straight lengths of pipe are available for your
application measurements are still obtainable, but the certainty of the measurement can be reduced.

INSTALLATION
3.3 Installation location
Select an installation location following the 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. In this way, 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.
For a free inlet or outlet pipe section:
Select the measuring point at a location where the pipe cannot run empty.
For a vertical pipe:
Select the measuring point at a location where the liquid flows upward to ensure that the pipe is completely filled.
Table 1: Recommendations for sensor mounting location
Look for a sensor installation location with suicient straight pipe to obtain accurate measurements. Please refer
to Table as a guideline for recommended distances from disturbance sources.

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 flowmeter diagnostics indicate
suicient signal strength.

3.5 Sensor mounting configurations and separation distance
3.5.1 Reflection Mode
The most common clamp-on sensor mounting configuration is the Reflection Mode, sometimes known as V-Mode (see
Picture 3, sketch 1). Here, the ultrasonic signal passes twice through the medium (two 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 accurately aligned. This method should be used whenever possible.
Picture 3: Clamp-on sensor mounting configurations and sensor spacing
3.5. Diagonal Mode
An alternative mounting configuration (see Picture 3, sketch 3) is the Diagonal Mode (Z-Mode). The signals travel only once
through the pipe. This method is oen used for larger pipes where greater signal attenuation might occur.
Further variation of the Reflection and the Diagonal Modes are possible by altering the number of passes through the pipe.
Any even number of passes will require mounting 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 mounting
configurations such as four passes (W-Mode) or three passes (N-Mode) are used (see Picture 3, sketch ).
3.5.3 Transducer separation distance
The transducer separation distance A is measured from the inside edges of the sensor heads as shown (see Picture 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 Picture 3, sketch 3). Negative separation distances may be suggested for Reflec-
tion Mode installations, but are not possible. In these cases, use Diagonal Mode or a larger number of passes.

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 suiciently charged,
•the sensors must be connected to the transmitter.
Depending on which sensor mounting method is being used, 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). The sensor spacing is calculated by the
flowmeter from the pipe parameters entered (see Section 3.5).
3.7.1 Acoustic coupling gel
In order to obtain acoustical contact between the pipe and the sensors, apply a bead of acoustic coupling gel
lengthwise down the centre of the contact area of the sensors.

INSTALLATION
3.7. Correct positioning of the sensors
Always mount the transducer pair so that the free front edges of the sensors face each other. There is a dierent
engraving on the top of each transducer. The transducers are mounted correctly if the engravings on the two
transducers form an arrow. The transducer cables should point in opposite directions. Later, the arrow, in con-
junction with the indicated measured value, will help to determine the direction of flow (see Section 3.3).
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. The sensor positioning screen (see Section 4.4) allows fine adjust-
ment of the sensor location.

3.7.3 Sensor mounting with fixtures and chains
•Insert the retaining clip into the groove on the top of the transducer and secure it using the screw knob.
•Apply some acoustic coupling component to the contact surface of the transducer.
•Place the transducer on the side of the pipe or alternatively up to 45 degrees from the horizontal plane
through 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 bottom of the pipe.
•Take the spring end of the chain in one hand and insert the last ball element in the vertical slot of the retain -
ing 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 suggested by the flowmeter. When the
sensor positioning screen is displayed, the middle bar allows fine adjustment of the sensor location.
