2 Bending radius ≥ 100 mm (3.94 in). Ensure strain relief to prevent the capillary from bending.
The maximum height difference depends on the density of the fill fluid and the lowest
absolute pressure that can ever occur at the diaphragm seal (empty vessel).
Information on cleaning
Endress+Hauser provides flushing rings as an accessory to enable the membrane to be
cleaned without removing the transmitter from the process.

by using pipe heat tracing
• Install the pressure piping with a monotonic gradient of at least 10%
