Installation
No special measures such as supports etc. are necessary. External forces are absorbed by the
construction of the device.
Mounting location
h
A0029343
Preferably install the sensor in an ascending pipe, and ensure a sufficient distance to the next pipe
elbow: h ≥ 2 × DN
To prevent measuring errors arising from accumulation of gas bubbles in the measuring tube, avoid
the following mounting locations in the pipe:
• Highest point of a pipeline.
• Directly upstream of a free pipe outlet in a down pipe.
Installation in down pipes
Install a siphon with a vent valve downstream of the sensor in down pipes whose length h ≥ 5 m
(16.4 ft). This precaution is to avoid low pressure and the consequent risk of damage to the
measuring tube. This measure also prevents the system losing prime.

Installation in partially filled pipes
A partially filled pipe with a gradient necessitates a drain-type configuration. The empty pipe
detection (EPD) function offers additional protection by detecting empty or partially filled pipes.
