In line seals are suitable for measuring the pressure of fluids in pipes. The pressure measuring diaphragm forms the pipe wall
making this type of seal suitable for measuring the pressure of flowing fluids particularly those that are highly viscous or contain
solids. This particular diaphragm seal is available only on direct-mount gauge and absolute pressure transmitters.
