Mounting Requirements
Refer to figure 2-4 for examples of the following mounting considerations:
Liquid Flow 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 Flow 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 Flow 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.
• Fill impulse lines with water to prevent the steam from contacting the
transmitter directly and to ensure accurate measurement start-up.
NOTE
In steam or other elevated temperature services, it is important that
temperatures at the coplanar process flanges not exceed 250 °F (121 °C) for
transmitters with silicone fill or 185 °F (85 °C) for inert fill.
