6.6 WIP Replacement
iMeter pulsers are in a black case, while Xflo meter pulsers are in a blue case. They are not in-
terchangeable.
Refer to Fig 6.8 below and Fig 6.12 in Meter Replacement section and replace the WIP as follows:
1
Cut and remove the seal wires on both calibration doors on the pulser.
2
For NA, remove the calibration seal slats, iMeter only. IEC does not use the sealing bracket
and pins.
3
Remove the pulser by removing (2) screws that secure the pulser to the meter dome.
4
For NA, remove the sealing bracket, iMeter only.
5
Press the two plastic tabs on end of pulser, lower the plastic cover, remove the rubber cap
that covers the small 8-pin connector, and disconnect the cable.
6
Connect the pulser cable to the new pulser. Align carefully - misaligned connector pins at the
pulser will prevent proper mode setting and calibration. Pin 1 on the connector inside the
pulser is located at the bottom of the pulser as shown in the figure below.
7
Re-install the rubber cap over top of connector and secure the plastic cover back in place
over the rubber cap and cable. Both ends of the cover must be snapped in place.
8
Install the new pulser, along with the sealing bracket if applicable, and secure with the (2)
screws. Do not install new seal wires at this time.
9
Follow the Pulser Operational Mode setting procedure and the Meter Verification Accuracy
procedure in this manual and, if required, continue with the iMeter calibration procedure.
10
Install the seal slats, if applicable, and seal wires after completing the above steps.
