Power Plants Use Radar Level Meters To Improve The Stability Of Ash Bin Measurement

In power plants, level meters are often used for level measurement of ash bins and other silos. The application of level meters in ash bins is challenging, similar to coal ash bins and dehydration bins in desulfurization systems. A power plant used RF admittance level meters, but encountered data fluctuations, severe offsets and data problems. These problems mainly stem from changes in dust, dielectric constant, pressure and temperature, which cause the level meter to hang on the material, affecting data stability and automatic control functions. It can only rely on manual experience to control the liquid level, which is inefficient and prone to roof bursting.

The plant then switched to SOLIDAT's power plant radar level meter, which had a relatively ideal effect. After a period of use, the output of the ash silo radar level meter was stable, able to achieve automatic control, and accurately reflect the level of the ash bin.

Despite this, the power plant radar level meter also experienced three types of problems: inaccurate instrument display, unreasonable parameter settings, and antenna contamination. The first two types of problems can be solved by software debugging and parameter adjustment, while the antenna contamination problem requires the use of an antenna with a purge function to deal with it.

Whether it is a radio frequency admittance level meter or a power plant radar level meter, there will be problems in the ash silo application. To ensure accurate measurement, it is necessary to select a suitable silo level measurement instrument and effectively solve the problems that arise during use.
