INSERTION paddle wheel flowmeter for
continuous flow measurement

8020

• 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

The paddle wheel flowmeter for continuous flow measurement is espe- Envelope Dimensions [mm] (see datasheet for details)
cially 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 DN20 to DN400 mm. The flowmeter produces
a frequency pulse signal, proportional to the flow rate, which can easily be
transmitted and processed by a Bürkert transmitter/controller.

1) Under reference conditions i.e. measuring fluid = water, ambient and
water temperature = 20 °C, applying the minimum inlet and outlet
pipe straights, matched inside pipe dimensions. Note:
The length of the sensor armature depends on
the fitting used. See data sheet Type S020.
