Diaphragm seals are mounted to existing connections, which
are welded to a pipeline, a process reactor or a tank.
The internal space between the diaphragm and the pressure
measuring instrument is completely filled with a system fill

The process pressure is transmitted by the elastic diaphragm
into the fluid and from there to the measuring instrument.
A diaphragm seal and its components are perfectly matched
to each other to ensure a reliable measurement.
Diaphragm seals offer the advantage that they can be easily
dismounted, e.g. for cleaning or calibration purposes.
