Operating conditions
Installation instructions
Mounting location
Correct measuring is possible only if the pipe is full. Avoid the following locations:
•
Highest point in the run. Risk of air accumulating
•
Directly upstream from an open pipe outlet in a down pipe
Installation of pumps
Do not install the sensor on the inlet side of a pump. This precaution is to avoid low
pressure and the consequent risk of damage to the lining of the measuring tube.
It might be necessary to install pulse dampers in systems incorporating reciprocat-
ing, diaphragm or peristaltic pumps. The sensor is shock and vibration resistant for
acceleration up to 2 g in accordance with IEC 68-2-6.
Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty
Pipe Detection (EPD) function offers additional protection by detecting empty or
partially filled pipes.
Caution:
To avoid the risk of solids accumulating, do not install the sensor at the lowest point
in the drain. It is advisable to install a cleaning valve.
