BF flush diaphragm flanged type - 1

BF – FLUSH DIAPHRAGM, FLANGED TYPE The BF construction has a seal body that is made of a blind flange. The weld of the diaphragm to the seal body is a wetted part and therefore diaphragm materials are mostly chosen the same as the flange material. The BF is typically used in combination with (differential) pressure transmitters for applications such as level, flow and (absolute) pressure measurement.
