Transmitter UNIVERSAL, remote version

UNIVERSAL, remote version • Displays both flow rate and volume
8025

(with two totalizers)
• On site calibration by Teach-In
Transmitter • Simulation of all output signals

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

• The wall-mounted version B
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.
