The paddle-wheel flow sensor for continuousflow measurement is especially designed foruse in neutral, slightly aggressive, solid freeiquids. The sensor is made up of a fitting (S012)and an electronic module (SE11) connectedtogether with screws. The Bürkert designedfitting system ensures simple installation of thesensor into all pipes from DN 06 to 65. It canalso be installed in fluid block systems.The sensor produces a frequency pulse signal,proportional to the flow rate, which can easily betransmitted and processed by a Bürkert remotetransmitter/indicator
