M-Series® Mag Meter
Field Verification Device
OVERVIEW
The Field Verification Device is a portable test device for the Badger
Meter M-Series® of electromagnetic flowmeters. The M-2000 and
the M-5000 meters can be tested using this device.
With the Field Verification Device, accurate verification of meter
functionality is assured without taking the meter out of the
pipeline (“wet” test) and interrupting functionality. Meter diagnosis
and calibration can be performed on-site. A “dry” test (removing the
meter and bench-testing) can also be performed. The complete
verification test consumes approximately 20 minutes and results
can be downloaded to a Microsoft® Windows® XP or Vista® personal
computer.
FEATURES
