FSO-USLF Internal Diaphragm Flanged Type

Brand: Badotherm

The FSO-USLF construction is similar to the USL-F design and typically used for those applications where the existing process connection is too small to use a flush mounted diaphragm seal. 

The specific advantage for the FSO-USLF is the efficient design with regards to exotic materials as the lower part is significantly smaller and also has a smaller weight. Also it allows for more flexibility in the different cover flange materials e.g. for pressure rating. And bolting pattern is standard as per the cover flange. 

FSO-USLF is typically used in combination with (differential) pressure transmitters for applications such as level, flow and (absolute) pressure measurement. The FSO-USLF has a large diaphragm and allows for measurement of low ranges (up to 10 mbar double (2) seals attached (dP); 80 mbar single seal attached).
