Flowmeter for continuous flow measurement

8012 • Economic integration in pipe systems

without any additional piping
• Optic measuring principle
• Configurable output: 1 analog
4 - 20 mA and/or 1 transistor output
(frequency or switch)
• Outputs configurable (through interface
on USB port with PC)

The flow meter with paddle wheel is particularly useful in the optical ver- Envelope Dimensions [mm] (see datasheet for details)
sion for use in infrared transparent liquids.
DN25
Type 8012 is made up of a fitting (S012) and an electronic module
(SE12) connected together with screws. The Bürkert designed fitting P
system ensures simple installation into all pipes from DN06 to DN65. It
can also be installed in fluid block systems.

Type 8012 produces a programmable frequency pulse signal, propor-
tional to the flow rate, which can easily be transmitted and processed by
a Bürkert remote transmitter/controller, or a programmable switch output
or a 4 - 20 mA signal. L
