CAP-3031-S-2-0-L Boiler Drum Water Level Gauge Description:

CAP-3031-S-2-0-LHigh pressure heater level gaugeThe importance of measurement is well known, but for a long time, the balanced container (differential pressure) measurement method used in the continuous measurement technology of boiler drum water level has many shortcomings that cannot be improved, mainly reflected in the following aspects:

1. Unable to implement full condition measurement, there are problems such as "false water level" measurement, long time to establish stable differential pressure conditions under unstable operating conditions such as boiler start, stop, exhaust, continuous discharge, accidents, etc., long recovery time, or simply unable to establish normal differential pressure, requiring manual intervention.

2. Under stable operating conditions, due to structural limitations, the compensation problem for system measurement errors caused by water side insulation cannot be solved. Under accident conditions such as boiler shortage and full water, excessive measurement errors in the system may lead to serious consequences.

3. Complex structure, multiple static sealing points, large construction scale, and winter insulation issues.

4. The measurement time delay is long, which cannot reflect the changes in boiler water level in real time, and the quality of measurement signal adjustment is poor.

5. Due to the heat release from the condenser, the usage cost is high.

These defects are all caused by the principle of differential pressure measurement and its unreasonable sampling structure in the system, and cannot be improved. This poses a great risk to the safe operation of the boiler under abnormal working conditions.

To solve the problems in measuring the water level of the steam drum, Henan Xinruipu Measurement and Control Technology Co., Ltd. has designed and produced a boiler steam drum water level measurement and control working condition

CAP-3031-S-2-0-LHigh pressure heater level gaugeIt is manufactured using advanced capacitance detection technology with full process measurement and automatic compensation function. Being able to achieve safe, reliable, and accurate measurement and control of the water level in the boiler drum under all operating conditions is of great significance for ensuring the safe, efficient, and energy-saving operation of the boiler. It can be widely used for liquid level measurement and control of pressure vessels such as industrial steam drums, high-pressure reactors, low-pressure reactors, and converters of various specifications.
