COMMISSIONING DIRECT
MOUNT PROPLATES/
MASS PROPLATES
The commissioning process differs according to the service used.
The following sections provide commissioning instructions for each
type of service.
Liquid Service This section provides instructions for commissioning direct mounted
ProPlate models used for liquid service in horizontal or vertical pipes.
Figure 4-1 identifies the valves used during the commissioning process.

Direct Mounted ProPlates in Liquid
Service.
Use the following procedure to commission the ProPlate.
1. Open the high and low manifold valves MH and ML.
2. Open the equalizer valve ME.
3. Open the drain/vent valves on the electronics; bleed until no air is
apparent in the liquid.
4. Close both drain/vent valves DVL and DVH.
5. Close the high and low manifold valves MH and ML.
6. Check the ProPlate zero by noting the electronics output—this is
called a wet zero. If the signal reads outside of the range 3.98 mA
to 4.02 mA, air is probably still in the system; repeat step 2, and
trim zero if necessary.
7. Open the high and low manifold valves ML and MH.
8. Close equalizer valve ME. The system is now operational.
Gas Service This section provides instructions for commissioning direct mounted
ProPlate models used for gas service in horizontal or vertical pipes.
Figure 4-2 identifies the valves used during the commissioning process.
