Compact INSERTION Batch Controller

8025 Batch Controller Compact • DN06-400 mm

• 4-20 mA output
• On-site calibration by TEACH-IN
• Check of input/output signals
• Total and daily totalizers for batch quantity
and number of batches, volume or mass
totalizers displayed

The compact batch controller combines a paddle-wheel flow sensor and Envelope Dimensions [mm] (see datasheet for details)
an electronic module with a display in an IP65 enclosure. The electrical
connection is provided via two cable glands.

Bürkert designed fitting S020 ensures simple installation of the Bürkert
sensor into pipes from DN20 to DN400.
