Inline Paddle Wheel Flow sensor for continuous flow measurement
The Type 8011 paddle-wheel flow sensor for continuous flow measurement is especially designed for use in neutral, slightly aggressive, solid-free liquids. The sensor is made up of a fitting (S012) and an electronic module (SE11) connected together with screws. The Bürkert designed fitting system ensures simple installation of the sensor into all pipes from DN06 to DN65. It can also be installed in fluid block systems.The sensor produces a frequency pulse signal, proportional to the flow rate, which can easily be transmitted and processed by a Bürkert remote transmitter/indicator (type 8025/8032). The sensor is available in two versions:- with one pulse output: transistor NPN- with two pulse outputs: transistor NPN and PNP.
The type 8011 is not available anymore since 1/1/23.
