USF – INTERNAL DIAPHRAGM, FLANGED TYPE The USF construction is designed for those applications where the existing process connection is too small to use a flush diaphragm seal. The USF consists of an upper and lower housing. The lower housing creates the transition from the diaphragm size to the actual small process connection. USF is typically used in combination with (differential) pressure transmitters for applications such as level, flow and (absolute) pressure measurement; also the USF is often combined with pressure gauges.
