Conduit Installation
Improper sealing of connections may damage the transmitter due to excess moisture
accumulation. Mount the transmitter with electrical housing positioned downward so that
the excess of moisture is condensed and drained out from the casing. Secondly, install
wiring with a drip loop and ensure the bottom of the drip loop is mounted lower than the
conduit connections or the transmitter housing to avoid moisture accumulation in the
housing.
NOTE
Conduit thread must be engaged with a minimum of 5 thread connections.

Mounting Requirements
Impulse piping configura
tion and transmitter position depends on
specific measurement
conditions. Follow the procedure below while installing transmitter for liquid, gases or steam
processes.
3.3.1
Liquid Measurement
•
Place the taps to the side of the line/pipe to prevent residue deposits on the
transmitter process isolators.
•
Mount the transmitter beside or below the taps so gases can vent into the process line.
•
Mount drain/vent the valve upward to allow gases to vent.
3.3.2
Gas Measurement
•
Place the taps in the top or side of the line.
•
Mount the transmitter beside or above the taps so liquid will drain into the process
line.
