Flushing ring

To rinse and clean a separator membrane

The flushing ring is an accessory intended to be mounted on the branch of a pipe upstream of a separator (connected to a pressure transmitter).

It offers the possibility of rinsing and cleaning the separator membrane if impurities are present - due to pitting (stagnation) or to the characteritics of the fluid to be measured. It thus allows reliable measurements of the process pressure.

It also helps for purge of the preocess and calibration of the transmitter.

Why and when to use a flushing ring?

When measuring the pressure of particularly aggressive, abrasive, corrosive, adherent or toxic fluids, the measuring instrument, i.e. the pressure transmitter, must be protected. It is then mounted on a separator whose membrane allows the separation of the fluid to be measured.

The separator membrane being highly stressed by these aggressive fluids, it is then necessary to install a flushing ring so that it can be rinsed and cleaned easily.
