3.2. Determining Installation Site

•

The installation site should be easy accessible and free of vibrations and shocks.

•

Observe at least 260 mm (10.24 inch) clearance above the housing with the signal conditioning, in

order to be able to remove the sensing probe if necessary.

•

The ambient temperature should not exceed the value as stated in the specifications (see page

20) – consider heating by radiation.

•

Air purity on the installation site according to ISO 8573-1:2010: at least class 3.4.4

•

The fluid should not condense at the installation site. Condensation on the tip of the sensing probe

must be avoided.

•

In compressed air systems, the installation must be downstream of the dryer. If there is no dryer, at

least steam trap and suitable filter must be present.

•

Observe the direction of the flow by the installation (see page 10).

•

Observe the recommended straight pipe lengths up and downstream, in order to warrant the speci-

fied measurement accuracy.

•

The flow sensor should be installed as far as possible from any flow disturbance. Valves or check-

valves should be installed in a respective distance from the flow sensor.

3.3. Installation Position

Make sure that the arrow on the tip of the sensing probe is pointing in the direction of the flow.
