Emerson Rosemount 1195 - Valve Identification

Rosemount Model 1195/ProPlate/Mass ProPlate
4-4
1. Install the ProPlate meter assembly.
2. Check the electronics for a dry zero of 4 mA with no water loss.
3. Fill the manifold and the transmitter with water.
4. Open the high and low main valves MH and ML and equalizer
valve ME to allow the assembly to equalize.
5. Close both MH and ML.
6. Check the ProPlate zero by noting the electronics output. If the
signal reads outside of the range 3.98 mA to 4.02 mA, air is
probably still in the system; repeat this procedure from step 2, and
trim sensor if necessary.
7. Open MH and ML.
8. Close equalizer valve ME. The system is now operational.
9. Line can now be pressurized.
10. For periodic maintenance check the wet zero. Close lowside ML,
open ME and MH.
REMOTE MOUNT
COMMISSIONING
Commissioning is the process of testing the ProPlate to ensure that it
operates accurately and safely.
COMMISSIONING REMOTE
MOUNTED FLOWMETERS
This section contains four procedures to follow in preparation for
commissioning a remote mounted ProPlate:
1. Identify the location and purpose of manifold valves.
2. Zero the electronics.
3. Check for system leaks.
4. Perform a zero calibration.
Valve Identification Before beginning the ProPlate commissioning process, you should
become familiar with the location and purpose of the various valves
involved. Figure 4-4 identifies the location of valves for both 5-valve
and 3-valve manifolds, and Table 4-1 identifies the purpose of those
valves.
Do not open the ME valve when steam line is pressurized because the water legs could
be removed.
