2600T SERIES |  PRESSURE TRANSMITTERS |  OI/266/FF-EN REV. E
Installation recommendations
Impulse piping configuration depends on the specific 
measurement application.
Steam (condensable vapor) or clean liquids flow measurement
•  Place taps to the side of the line.
•  Mount beside or below the taps.
•  Mount the drain/vent valve upward.
•  In case of steam application fill the vertical section of the 
connecting lines with a compatible fluid through the filling tees.
The process fluid must enter the transmitter primary:
1  Open equalizing valve (C)
2  Close low pressure (B) and high pressure (A) valves .
3  Open gate valves
4  Slowly open high pressure (A) valve to admit process fluid to 
both sides of primary.
5  Vent or drain the primary unit and then close the valves.
6  Open the (B) valve and close the equalizing valve.

Gas or liquid (with solids in suspension) flow measurement
•  Place the taps to the top or side of the line.
•  Mount the transmitter above the taps.
