The boiler level gauge has the function of accurate continuous measurement and control of the liquid level under all operating conditions, and can automatically compensate for changes in the liquid medium, dielectric constant change, vapor medium, and dielectric constant. Key adjustment, easy calibration, with self-diagnosis, full temperature range, measurement system, temperature drift no more than 0.1PF, electrode using non-metallic materials, mechanical and electrical integration. The intelligent boiler drum liquid level gauge has the advantages of high temperature resistance, high pressure, long life, high reliability, high precision, and high stability. It can be widely used in various specifications of industrial steam drums, high-increasing, low-adding, reformer and other pressure vessels. Bit monitoring.

       The importance of boiler level gauge water level measurement is well known. However, there are many unrecoverable defects in the balanced container type (differential pressure) measurement method used for continuous measurement of boiler drum water level, which is mainly reflected in the following several aspects:

1. It is not possible to carry out full working condition measurement, there is a “false water level” measurement, and it takes a long time to establish a stable differential pressure condition under unstable operating conditions such as boiler start, stop, emptying, continuous row, accident, etc., or a long recovery time. It is impossible to establish normal differential pressure and require manual intervention.

2. Under the stable operating conditions, due to structural constraints, the compensation for system measurement errors caused by the temperature at the water side cannot be completely resolved. Under the conditions of accidents such as boiler shortage and full water, excessive system measurement error may bring serious consequences.

3. The structure is complex, there are many static seal points, the construction scale is large and there is a problem of winter insulation.

4, the measurement time lag is long, can not immediately respond to changes in the boiler water level, measurement signal quality is poor.

5, due to the existence of condensation tube heat, the use of high cost.

These defects are due to the differential pressure measurement principle and its unreasonable sampling structure, and cannot be improved. Under normal operating conditions, it has caused great dangers for the safe operation of boilers.

The company's boiler level gauge uses a unique structure, high temperature, high pressure, in which the transmitter uses the relationship between the change of the liquid level and the change in the capacitance of the measuring probe, through the special mode system software will change the detected capacitance After the compensation calculation, the 4-20mADC standard signal, which is proportional to the material level, is output. With high precision, high stability, high temperature, high pressure, long life characteristics.
