KATflow 150 Quick Start Manual
Flow in pipe
Step 1: Selection of measurement point & pipe preparation
●Avoid installation of sensors in the vicinity of deformations and
pipe defects, near welding seams or where deposits could have
accumulated.
●Select a measuring point with sufficient straight pipe to obtain
accurate measurements. Please consult the manual for the
recommended distances from sources of disturbance.
●For a horizontal pipe, mount the sensors on the side of the
pipe. For a vertical pipe, mount the sensors at a location where
the liquid flows upwards. (Pic 1)
●Mount the sensors in the direction of the flow. (Pic 2)
●Clean the pipe at the measurement point. Remove loose paint
and rust with a wire brush or file.
●Apply coupling paste to the face of the clamp-on sensors before
attaching them to the pipe.

Step 3: Quick Start menu and Setup Wizard (continued)
Select number of sound passes
(sound paths) using cursor keys.
Auto: Selection by flow meter
according to entered parameters
(number of passes shown later
on Sensor Positioning Screen).
1: 1 pass, (diagonal mode)
2: 2 passes (reflection mode)
3: 3 passes (diagonal mode)
4: 4 passes (reflection mode)
5: 5 passes (diagonal mode)
..etc.
1. Reflection mode
The flow meter uses an even number of passes. This is the most
convenient mounting arrangement, as the transducer separation
distance can be measured very easily and the sensors can be
accurately aligned. Use whenever possible. (Pic 3)
2. Diagonal mode
Signal travels on odd number of passes through the pipe. Used
for larger pipes and for dirty/aerated liquids where greater signal
attenuation can occur. The sensor distance on this mounting con-
figuration can be negative (sensors overlapping). (Pic 4)
The main measurement unit is
displayed when first entering the
measurement screen.
Press MUX to switch between
channels 1 and 2. Press NEXT
to see up to 3 units displayed
with the main one in the middle.
KATflow 150 Quick Start Manual
With correct pipe parameters entered and the sensors mounted
at the suggested spacing, the mark should be near the central
indication line (see three lines below the bottom signal bar). If the
mark is to the left-hand side of the central indication line, the
sensors are too close to each other. If the mark is to the right, the
sensors are too far apart. Slide one sensor carefully along the
pipe to bring the mark into a more central position. Measure-
ments can be obtained with the mark being between the left and
right indication line. Press ENTER to start measurement.
Two further measurement units can be assigned to that screen
by going to Main Menu - Display - Channel 1 / Channel 2.
Even number of passes: Both sensors on same side of pipe. Odd
number of passes: Sensors on opposite sides (see below for
more information). Confirm with ENTER. Your second channel
can be prepared now by selecting Setup Wizard CH1 or CH2.

2. Diagonal mode
Signal travels on odd number of passes through the pipe. Used
for larger pipes and for dirty/aerated liquids where greater signal
attenuation can occur. The sensor distance on this mounting con-
figuration can be negative (sensors overlapping). (Pic 4)
Mount the transducers with the suggested spacing between the
inside of the sensor heads. This distance has been determined
by the flow meter on the basis of the entered parameters. Use
the displayed number of passes to install the sensors on the
correct side of the pipe (see modes above). Observe the upper
bar (signal-to-noise ratio) and lower bar (signal quality). These
should both be filled to about the same level with a filling level of
around 1/3 or more desired. Use the moving mark between the
two signal bars for fine adjustment of the sensor position.
Internal data logger
The totalizer is shown when in measurement mode after pressing
NEXT three times. It can also be assigned to the three line
display, datalogger or process outputs by selecting a volumetric
unit. The totalizer function is started with QON when in mea-
surement mode (measurement screen displayed). Pressing Q+
resets the total in positive flow direction. Pressing Q- resets the
total in negative flow direction. The totalizer function can be
stopped with QOFF. Pressing QON again will reset the positive,
negative and overall totalizer. Change displays without resetting
the totalizer by pressing DISP or NEXT.

flow channel which the temperature input has to be applied
to. You can choose between Channel 1 or 2. Selecting OFF
will disable the input. Confirm with ENTER.
3.) On the following screen choose PT100 to employ the tem-
perature measured on the pipe. If you wish to enter a fixed
temperature value, select User and enter the value.
4.) As next step define whether the PT100 sensor measures
the inlet or outlet temperature. Use the cursor keys to select
the appropriate and confirm with ENTER.
5.) On the next screen a temperature offset can be applied.
After confirming again with ENTER you reach the Main
Menu.
Once the setup of the first temperature input has been completed
repeat steps 1 to 5 for the configuration of the second input.
Process in/outputs: Setup
KATflow 150 Quick Start Manual
The KATflow 150 is capable of measuring heat flow and heat
quantity. If you wish to measure heat flow, select a heat flow unit
(W, kW, MW) as Middle Unit when going through the Setup
Wizard of the selected measurement channel. If you wish to
measure heat quantity, select a heat quantity unit (J, kJ, MJ).
On selection of one of these units, the flow meter requests the
entry of the specific heat capacity of the medium in J/(g.k). Enter
the value for your fluid and confirm with ENTER. Complete the
remaining steps of the Setup Wizard.
The temperatures at the inlet and outlet of the monitored system
are used to determine heat flow and heat quantity. Connect 4-
wire PT100 temperature sensors to the flow meter as per the
illustration below. (Pic 5)

For separate measurement of flow and temperature select a flow
unit as Middle Unit in the Setup Wizard. Complete the wizard and
then go to Main Menu - In/Output. Assign one PT100 input to the
flow channel as described on the left. Define it as an inlet tem-
perature source.
Now go to Main Menu - Datalogger - Selection and choose Tin
as one of the recorded measurement units. Upon start of each
measurement the flow meter will now record selected flow units
as well as the temperature measured by the PT100 sensor.
In/outputs can be set up in Main Menu - In/Output. Depending on
which in/outputs are available, the displayed list contains one or
more in/outputs. The in/output listed at the very top of the list is
available on Slot 1 inside the connection compartment, the in/
output listed second from top is available on Slot 2 and so on.
After selecting an in/output, it can be assigned to a measuere-
ment channel. The structure of the further steps depends on the
individual type of output.
Process in/outputs: Connection
In/outputs can be connected to devices via screw terminals.
These can be found inside the connection compartment below
the control panel. Remove the screws at the left and right to gain
access to the compartment.
Connection to the outputs can be established by wiring transfer
cables into the respective terminal blocks of the I/O box. The
illustration below gives an overview of the terminal assignment.
