Drum Level Deviation

04/27/2010 5:53 AM

We are having 3 drum level transmitters in our boiler.The reading of the transmitters are widely different.the range of the transmitters are 0 to 860 mm H2O.the working range of the transmitters is +430 to - 430 mm.Can there be any problem with the compensating curve.What can be the other reason for this deviation?

Not my field, but...That doesn't make sense to me as the second pair of figures isn't a subset of the first pair of figures.
Some figure to illustrate 'widely different' might help?
Are the transmitters the same type?

What sort of level transmitters - are these actually differential pressure instruments (if so then ranging one below zero makes little sense at the moment)?
