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 NEXT to see up to 3 units
displayed with the main one in
the middle.
KATflow 200 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 - Output - Display .
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.

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 be both 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 the 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.

Totalizer
The data logger is reached via Main Menu - Output. It is activated
in Datalogger - Interval by entering and confirming a non-zero
value. Enter “0” and confirm to disable the logger. Up to 10
measurement units can be seleceted for logging under
Datalogger - Selection. Use the cursor keys to highlight a unit
and press ENTER to select it. Press “0” to deselect it. An
activated data logger is indicated by a “document” symbol in the
top left corner of the display. On start of measurement (measure-
ment screen displayed) the logger records the selected measure-
ment units. A blinking “document” symbol indicates a recording
data logger. Separation markers are set by the data logger
whenever a session beginns. Leave the measurement screen by
pressing ESC to stop recording. The recording interval can be
changed in Datalogger - Interval. The data logger is cleared
under Datalogger - Log Erase. Ensure all required data has been
downloaded .
