Measurement of boiler level
Thread Content
I would like to ask everyone: Have you used diaphragm flange differential pressure transmitters to measure boiler levels? If you have used it, how was the effect? How does the boiler temperature affect the susceptibility of the diaphragm to damage, the accuracy of level measurement, and the amount of maintenance work required?
In my opinion, due to the high water temperature in the boiler and the significant changes in water density as temperature varies, a balance vessel is generally used to ensure the accuracy of boiler level measurement. In this case, there is no need at all for a diaphragm seal differential pressure transmitter, and it is also difficult to install such a transmitter...
I agree with the view expressed above: using diaphragm-flanged differential pressure transmitters not only places high demands on such transmitters, but also poses risks to the safe operation of boilers; it is recommended to use balance vessels
A two-chamber balanced level gauge is generally used.
