3.4.2Measurement of vapours and gases

Prohibited installation

1Lower pipe bends

2Condensate

DANGER!

Prohibited: Installing the device in a lower pipe bend 1, because there is a risk of condensate forming 2.

Condensate can lead to cavitation and inaccurate measurement. Under certain circumstances the device can be destroyed and the measured product can leak.

Recommended installations

CAUTION!

It is absolutely necessary to maintain the required inlet and outlet runs.

1Inlet and outlet falling

2Rising inlet - falling outlet
