Steam Flow Measurement
• Place taps to the side of the line.
• Mount the transmitter below the taps to ensure that impulse piping will
remain 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.
NOTE
For steam or other elevated temperature services, it is important that
temperatures at the process connection do not exceed the transmitter’s
process temperature limit, which is 250 °F (121 °C).
