Transmitter, remote Version

8025 Transmitter remote Version • Only for Bürkert flowmeters in

„Low Power“ version
• Displays both flow rate and volume
(with two totalizers)
• On site calibration by Teach-In
• Simulation of all output signals

The 8025 flow transmitter with display, is available in wall-mounted and Dimensions [mm] (see datasheet for further details Details)
panel versions:

• The panel version
is made up of an electronics integrated in an open housing with dis-
play. The electrical connection is carried out on the terminal blocks of
the electronic board
B
• The wall-mounted version
is made up of an electronics integrated in a housing with cover, display.
The electrical connection is carried out on the terminal blocks of the
electronic board via 3 cable glands.
