Insertion flowmeter with paddle wheel for continuous flow measurement - Burkert Type 8020

Specially designed for use in neutral, slightly aggressive, solid free liquids.

Water, waste water monitoring, chemical processing, etc.

Flowmeter with Paddle Wheel
  • Description
  • Specification
  • Downloads

The flowmeter with paddle wheel for continuous flow measurement is especially designed for use in neutral, slightly aggressive, solid free liquids.

The Bürkert designed fitting system ensures simple installation of the devices into all pipes from DN 20…DN 400.

The flowmeter produces a frequency pulse signal, proportional to the flow rate, which can easily be transmitted and processed by a Bürkert transmitter/controller.

Featuring:

  • Economic integration in pipe systems without any additional piping
  • 3-wire frequency pulse version to directly interface with PLC’s (both PNP and NPN)
  • Connection to Bürkert devices in remote versions
