Recommended Location
The recommended installation mounts the ProPlate electronics above
the process piping to prevent condensable liquids from collecting in the
impulse piping and DP cell. Figure 2-29 illustrates the recommended
electronics location for use in a horizontal or vertical pipe.
Figure 2-29. Recommended
Electronics Installation for Gas Service:
A (horizontal pipe) and B (vertical
pipe).
Alternate Location
When it is impractical or impossible to mount the ProPlate electronics
above the process piping, the electronics can be mounted below the
process piping as shown in Figure 2-30. This alternate installation
requires periodic maintenance to assure that condensate from
saturated gas applications is drained from the chambers. Figure 2-30
illustrates the alternate location for use in either a horizontal or
vertical pipe.

Steam or Liquid Service above 450°F (232°C)
For steam service (at any temperature) or liquid service at
temperatures above 450°F (232°C), the ProPlate electronics
must be installed below the process piping.
NOTE
Steam (or hot water) must not enter the electronics. Fill the system of
impulse piping and ProPlate electronics with cool water before
pressurizing the system.
