2003年6月22日 · The wet leg method is the most difficult one to calibrate as the measurement will indicate 0% when the tank is full and 100% when it's empty. Also after installation, it may take quite a while before the measurement actually indicates the correct level unless you are able to manually fill the compensation line.

2020年12月18日 · A cold and wet sensation in random areas of the body and on patches of skin can become a very irritating situation which brings up more questions than it does answers. The sensation is usually described as someone feeling something wet or cold on their skin despite there being no sweat or other fluids present, as well as no cold object nearby ...

2014年8月30日 · Hi We have many DPTs installed as flow transmitters along with orifices on pump discharge lines @ liquid ammonia service. The impulse lines are filled with glycol or some other material to create a wet leg and not to allow liquid ammonia to enter the impulse lines. But what we have observed...

2007年11月7日 · Wet leg is used normally in level measure, because if the gas or steam (water, HC) inside the drum condensate to ambient temperature, this condensate will begin to fill the empty tubing connected to the top of the drum, then this produces a small column of liquid that will go rising through the time and your LRV (zero) will not be the same that ...

2001年3月5日 · Hello List About 12 months ago I seen a thread about keeping the wet leg for a Dp transmitter open from blockages. The application is for sump levels in a coal preparation plant. Where slurry or magnetite especially after a shutdown have a …

2011年8月26日 · Fill the wet leg with the sealing fluid Look at the process value on the communicator and write this down. It should be 140 * 1.2 = -168" H2O This is your LRV or Zero - your span from this which is 80" H2O This will be -168 +80 which will be -88" H2O This is your upper range value which will be -88" H2O This is your transmitter calibrated range
