1 How to calculate dp transmitter
steam and water?
2 impulse line for liquid steam and
gas
Answer Posted / carl_ellis
The DP pressure/flow transmitter is mounted above the pipe
for gas applications (empty impulse tubing).
The DP pressure/flow transmitter is mounted below the pipe
for liquid applications (liquid filled impulse tubing)
Steam flow applications using DP pressure transmitters were
historically mounted below-the-pipe (water filled impulse
tubing, frequently with condensate/seal pots), until
Emerson/Rosemount recently discovered that within certain
temperature limits, a DP transmitter close coupled on a
coplanar manifold to an Annubar averaging pitot tube can
survive steam temperatures mounted above-the-pipe.
See this link for Emerson's white paper on steam service
installation recommendations:

i have used level transmitter in starch cooking preparation tank. tank total height 2mtr.sometime LT display shows some error value when tank is fully empty and diaphragm side i already checked okay no problem in diaphragm area. field cable checked 24volt and mA shows correct value while tank empty mA is 4mA. 4mA i needed that 0% but display showing 10% or 15% percentage values are varying continously please give any good solution for me.....
