Method Using the Data Setting Device
Introduction
Adjust the electromagnetic flowmeter so that the instantaneous flow when the
fluid in the detector stands still is measured as zero.
Notes:
• Zero adjustment is very important for accurate flow rate measure-
ment.
Be sure to zero the flowmeter before it is first operated.
• Before zero adjustment, make sure the detector is correctly Class
3 grounded and that the fluid to be measured has been charged
and stands still in the detector. Zero adjustment becomes possible
when the flow speed is 0.2 m/s or less, but wait until the fluid com-
pletely stops (Flow speed: 0.0 m/s) for accurate adjustment. Oth-
erwise, output errors may result.
