Impulse piping
Mounting requirements
Impulse piping configurations depend on specific measurement conditions. Refer to
3-9
for examples of the following mounting configurations:
Liquid measurement
•
Place taps to the side of the line to prevent sediment deposits on the transmitter's
process isolators.
•
Mount the transmitter beside or below the taps so gases can vent into the process line.
•
Mount drain/vent valve upward to allow gases to vent.
Gas measurement
•
Place 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.
Steam measurement
•
Place taps to the side of the line.
•
Mount the transmitter below the taps to ensure that the impulse piping will stay filled
with condensate.
•
In steam service above 250 °F (121 °C), fill impulse lines with water to prevent steam
from contacting the transmitter directly and to ensure accurate measurement start-up.
NOTICE
For steam or other elevated temperature services, it is important that temperatures at the
process connection do not exceed the transmitter's process temperature limits.
