Flow Meter Calibration
The Sample Sentry II system has a stated flow accuracy of ± 3% of full scale which
correlates to ± 102cc. Under normal operation of the system this value is fine; however, if
additional accuracy is required it possible to generate a multiple point correlation table to
normalize each system to a specific sample point. The default values for the screen are:
ƒ Setpoint 1: 0 = 0
ƒ Setpoint 10: 3393 = 3393
If you want to make adjustments to this table please consult Sentry Equipment for a
detailed procedure or field service assistance.
