Basic Ordering Information
Electrical connections
Rotating flange diaphragm seals – flush and extended (S26RA, S26RE, S26RH and S26RJ
The extended and flush diaphragm remote seal is designed to connect to flanged pipe fitting, according to ASME B16.5 (S26RA), EN 1092-1 (S26RE), JIS B 2220 standards (S26RJ) or ISO 10423 (S26RH). For liquid level measurement installations the seal connects to a flanged tank nozzle, compliant to the relevant standard. The sealing is provided by a selectable smooth or serrated gasket seat surface finish. The mounting flange is of rotating type and can be supplied on carbon steel or in stainless steel AISI 316
