Flowmeter with Paddle Wheel for Continuous Flow Measurement
The Bürkert Type 8012 paddle wheel flow meter is available in magnetic or optical version. The magnetic version of the measuring instrument is especially designed for use with neutral, slightly aggressive, solid free liquids. The optical version is exclusively intended for use with infrared transparent liquids. Type 8012 consists of a fitting ( Type S012) and an electronic module (Type SE12) which are connected together with screw. The Bürkert designed fitting system ensures simple installation into all pipes from DN06…DN65. It can also be integrated in customer-specific block systems. Depending on the electronics module, the 8012 is equipped: – with a pulse output or – with a pulse output and a 4…20 mA current output. The pulse output, which can be transmitted and processed by a Bürkert remote transmitter/controller, generates a configurable frequency proportional to the flow rate or can be used as a switch output.
