How to calibrate the magnetic flow meter and how to correct
the flow if it is showing more flow.
Answer Posted / muzaffar ahmed
if the instrument is online calibration can be done by
closing the valve at upstream and downstream side.now the
meter should be
read zero if not recalibrate it.always remember while
calibrating magnetic flow meter the meter should be filled
with fluid and fluid should be conductive.
and other wise condition as such so you should be done by
analog to digital trim.
