Answer / shiv

milli meter water column used to measure pressure

Is This Answer Correct ?    105 Yes 11 No

why use MMWC unit..

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.

Is This Answer Correct ?    90 Yes 7 No

why use MMWC unit..

Answer / mpinst2008

MMWC MEANS MILLI METER OF WATER COLOUM,AND THIS A UNIT TO
MEASURE PRESSURE.

Is This Answer Correct ?    36 Yes 2 No

why use MMWC unit..

Answer / nikhil vaghela

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.

why use MMWC unit..

Answer / rohan

That is correct.but why we use this unit.what is the basic
reason of using 'mmwc'

Is This Answer Correct ?    20 Yes 5 No

why use MMWC unit..

Answer / rohan

pressure p = height * sp.gravity * density
Density of water is unity.For this reason low pressure
measurement is done using mmwc unit.

Is This Answer Correct ?    19 Yes 5 No

why use MMWC unit..

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.

Is This Answer Correct ?    13 Yes 5 No

why use MMWC unit..

Answer / vahid yaseri

mmWc MEANS MILLI METER OF WATER COLUMN & its used for low
pressure

Is This Answer Correct ?    13 Yes 5 No

why use MMWC unit..

Answer / jay

it means if we are using a fluid having dencity under 1 will be a more accurate resulting unit? to Rohan

2 Answers   Almeer Technical Services,


generally transmitter power supply having some range(12v to 35v) but the out put(4-20 mA) must same for given input.If we vary the power supply voltage then output mA also to be change according to V=IR. Is there any voltage regulator in the transmitter ?
