Boiler drum level gauge

Boiler drum liquid level gauge is a liquid level meter based on the capacitance measurement principle. It is widely used in liquid level measurement and control of pressure vessels such as boilers and other industrial drums, high-pressure tanks, low-pressure tanks, and reforming furnaces. This liquid level gauge uses tomography technology to compensate for the effects of changes in temperature, pressure, etc. by measuring and analyzing the dielectric constant of liquid and gaseous media in the barrel. After microprocessor operation and processing, it outputs a current signal that meets industry standards, and can also output an R digital signal for use. B Boiler drum level gauge is not affected by dielectric constant changes, boiler temperature changes, steam interference, etc. during operation. Because it has no impact on the liquid level gauge, its measurement accuracy reaches more than one thousandth, its long-term stability is very good, and there is almost no drift. It is unparalleled by other measurement methods. It is a boiler liquid level measurement product with high precision and high reliability under all working conditions.

Boiler drum level gauge maintenance matters:
When the drum level gauge has been installed in place , at this time the air valve, liquid valve, and drain valve are all closed. Please follow the steps below:
Open the liquid valve slowly, and carefully observe whether the measuring cylinder, welds, and flanges are leaking, leaking, or dripping , leakage phenomenon
, liquid level gauge preheating minutes
, slowly open the air valve
, check whether the output current signal is within the normal range
, open the drain valve as needed, and discharge the measurement Cold water and dirt in the cylinder can be removed to speed up circulation and improve measurement
. After the liquid level gauge works normally, the measuring cylinder can be insulated, which will help improve the measurement accuracy.
