guidelines
The sensor must be mounted as shown in the
left figure. Do not mount the sensor as shown in
the right figure. This will position the electrodes
at the top where there is possibility for air bubbles
and at the bottom where there is possibility for
mud, sludge, sand etc.
Recommended installation is in a vertical/in-
clined pipe to minimize the wear and deposits
in the sensor.
To achieve accurate flow measurement it is
essential to have straight lengths of inlet and
outlet pipes and a certain distance between
pumps and valves.
It is also important to center the flowmeter in
relation to pipe flanges and gaskets.
For accurate flow measurement, the sensor
must be installed in a section of straight pipe,
free of valves, elbows, tees, etc.

Inlet and outlet conditions
Avoid:
· Installation at the highest point in the pipe
system
· Installation in vertical pipes with free outlet
For partially filled pipes or pipes with downward
flow and free outlet the flowmeter should be
located in a U-tube.
Recommended flow direction: upwards. This
minimizes the effect on the measurement of any
gas/air bubbles in the liquid.

Installation conditions
(continued)
To ensure optimum flow measurement, atten-
tion should be paid to the following:
The sensor must always be completely full with
liquid.
