Answer / khushwant
mmWC = millimeter of water column.
The unit is used to measure pressure in low range.
It means that tank with a height of 10m filled with water.
then pressure in that tank will be 10000mmWC.
because density of water is 1.

Answer / mpinst2008
MMWC MEANS MILLI METER OF WATER COLOUM,AND THIS A UNIT TO
MEASURE PRESSURE.
Is This Answer Correct ? | 36 Yes | 2 No |
use to measure the pressure at very high accuracy.
Its used in deaerator and furnace pressure measurement.
Where the accuracy is required.
1 kgCM2 = 10000MMWC.
Is This Answer Correct ? | 32 Yes | 5 No |
Answer / jagdish
pressure P = height*acc. due to gravity* density
density of water is unity. due to this a small pressure
change gives large displacement in water colum and thus we
get accurate reading. so used mmWC.

I have a steam flow DP transmitter that has output swinging. Steam valve is in manual.I have good steam pressure. The impulse lines have steam tracing on them. The steam tracing has a hole in it that is blowing raw steam on the high side impulse line only. Could this be causing the swinging?
