USL FH – INTERNAL DIAPHRAGM, FLANGED TYPE The USL FH construction is designed for those applications where the existing process connection is too small to use a flush diaphragm seal. The USL FH consists of an upper and lower housing, the upper is the actual seal part with a diaphragm size that allows for measurement of low ranges (10 mbar 2 seals attached (dP); 80 mbar single seal attached). The lower housing creates the transition from the diaphragm size to the smaller process connection. USL FH is typically used in combination with (differential) pressure transmitters for applications such as level, flow and (absolute) pressure measurement.
