Smart differential pressure transmitters
Smart differential pressure transmitters with direct diaphragm seals
Smart or analog differential pressure transmitters with diaphragm seals for level measurement to pressure tank with gas-filled negative pressure line are recommended transmitters with diaphragm seal mounted on "+" side to pressure tank with liquid-filled negative line are recommended transmitters with diaphragm seal mounted on "-" side and converted output signal.
