5.5 Fixed flange diaphragm seals – flush and extended (S26FA, S26FE)
These diaphragm seal are designed to connect to flanged pipe fitting, according to ASME or EN standards. For liquid level
measurement installations, the seal connects to a flanged tank nozzle, compliant to relevant standard. The sealing is provided by a
selectable gasket seat surface finish. The "fixed" mounting flange is integral with the seal.
