8020 Insertion Flowmeter with Paddle Wheel
Brand: Burkert Fluid Control Systems
The paddle wheel flowmeter for continuous flow measurement is especially designed for use in neutral, slightly aggressive, solid free liquids. The Burkert designed fitting system ensures simple installation of the devices into all pipes from DN20 to DN400.
The flowmeter produces a frequency pulse signal, proportional to the flow rate, which can easily be transmitted and processed by a Burkert transmitter/controller.
Features- 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 Burkert devices in remote versions
