3.4.1 Measurement of liquids

Prohibited installation

Figure 3-2: Upper pipe bend

CAUTION!

Prohibited: Installing the device in an upper pipe bend 1, because there is a risk of gas bubbles 2 forming. Gas bubbles can lead to pressure surges and inaccurate measurement.

Figure 3-3: Downpipe and outlet

CAUTION!

Prohibited: Installing the device in a downstream pipe 3 or upstream pipe of a outlet 4. There is the risk of partially filled pipes.
