4.10 Vertical mounting in
pipe
Locate the unit low in the pipe system in order to avoid under pressure in the sensor and
consequent air separation in the liquid.
Flow direction If possible, the liquid should flow up-wards to
make bubble removal easier.
With vertical mounting, a check valve, which
closes on zero flow, must always be installed
so that the liquid cannot flow back and partially
empty the sensor.
The arrow on the sensor indicates positive
(forward) flow direction.
To facilitate 0-point adjustment, a valve with a good shut-off should always be mounted in line with
the sensor.
- The sensor should be completely filled with liquid.
- The valve must be closed.
- Wait a few minutes to let the flow stabilize at zero.
- Activate the 0-point adjustment, see Chapter 7 "Setting the 0-point".
