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 diaphragm seal fill fluid
and the lowest absolute pressure that can ever occur at the diaphragm seal (empty
container).
Cleaning instructions
Hauser provides flushing rings as an accessory to enable the process membrane
to be cleaned without removing the transmitter from the process.

Installing pressure piping
• For recommendations for routing pressure piping, refer to DIN 19210 "Differential
pressure piping for flow measurement devices" or the corresponding national or
international standards
• When routing the pressure piping outdoors, ensure sufficient anti-freeze protection, e.g.
by using pipe heat tracing
• Install the pressure piping with a monotonic gradient of at least 10%
