Batch Controller for panel or wall mounting

8025 Batch controller 7 batch sizes, 2 relay outputs

• Controls 7 batches automatically
• Fast fill and fine control for accuracy
• Shows both flow rate and volume

See flow sensor 8020, 8030, 8070

The remote 8025 batch controller can be connected (with pulse output Envelope Dimensions [mm] (see datasheet for details)
signal) with Bürkert flowmeters Type 8020, 8030, 8070 or other flow
sensor devices which emit a frequency signal.
Wall Mount
The remote 8025 is a batch controller with display, available in wall- A B C
mounted and panel versions: 126 90 149
The panel version
is made up of an electronics integrated in an open housing with display.
The electrical connection is carried out on the terminal blocks of the
electronics board
The wall-mounted version
is made up of an electronics board which is integrated in a housing with
a cover and display. The electrical connection is made via the terminal
blocks of the electronic board via 5 cable glands.
