Additional Input Options - Badger Meter Blancett B2800 Standard User Manual

ADDITIONAL INPUT OPTIONS

The B2800 flow monitor is capable of receiving magnetic pickup input (small signal sine
wave) or a contact closure input (pulse)� Since most Blancett turbine flow meters use a
magnetic pickup, the B2800 flow monitor is shipped configured for magnetic pickup input�
To change to a contact closure input, remove JP2 from the top two pins and jumper them
to the bottom two pins� See
