Flow Meter Calibration
Activate the Reset push button switch to enter the new
data.
NOTE: If S2 is in the plus (+) position, and S3 and S4
are at 15 as an example, then moving the posi
tion of S3 and S4 to 00 will provide a (0.03 x 15)
=.45% increase in the prover volume. To obtain
a greater increase in the prover volume, S2
must be placed in the minus (-) position and S3
and S4 rotated to the proper position to obtain
the desired change in pulse resolution. The
opposite is true if S2 is already in the minus (-)
position at the beginning of calibration.
Finally:
Re-seal the flow meter.
Enter date and % correction on the permanent flow
meter record.
As long as degree of change is moderate, the flow meter is
in good condition.
If there is a sudden significant jump in correction required,
the rotors are likely about worn out. Rotor replacement
should be consid-
ered now, rather
than letting further
wear cause rotors to start rubbing on flow meter housing.
