Installation - Recommendation
A straight inlet or outlet section is not required for AXONIC ultrasonic volume measuring meters. However, an inlet and outlet section of at least 5 x DN is recommendable if sufficient space is available.
Installation recommendations
The choice of installation site must ensure air cannot collect in the meter.

Installation – Recommendations
Pulse transmission interference
In case of interference during the pulse transmission between the pulse
generator and the pulse receiver, (i.e. cable is in the same duct as power cable), we recommend shielded and twisted cables.
