4.9 Horizontal mounting
in pipe CMF B-F
Locate the sensor low in the pipe system in order to avoid low pressure in the sensor and
consequent air separation in the liquid.
If the flowmeter is mounted horizontally it is self-emptying.
With low flow, horizontal mounting is recommended, any air bubbles are easier to remove.
Flow direction
The arrow on the sensor indicates the direction of flow defined as “positive” (the meter is able to
measure flow in both directions).
If possible, the liquid should flow in the forward direction to avoid partial emptying of the sensor,
especially with low flow.
In addition there should be a valve (check/solenoid) that closes when the flow is zero so that the
liquid does not flow back and causes partial emptying of the sensor.
To facilitate 0-point adjustment, a valve with a good shut-off should always be mounted near 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".
