Which sensor is used to measure the continuous level of coal powder?
Thread Content
It’s now impossible to make direct measurements using radio frequency admittance. Later, radar waveguides were used, but their response speed was too slow; water vapor present in the coal powder would eventually condense on the waveguide rods, making measurements impossible. Moreover, dust is generated during the injection of coal powder, which also prevents the use of ultrasound
For such issues, it is best to list the process and equipment conditions as well; consider using a weight-type level gauge.
If I remember correctly, the coal powder in Shell’s gasification process is measured using a radioactive level gauge……
The weight-type one works. Our previous limestone powder silos used a sledgehammer type, from an American brand
Do sledgehammers have a high failure rate?
Occasionally, the rope comes loose from the pulley, and there are also encoder failures
For our fly ash, we use high-frequency radar, and it does have an impact when causing fluctuations in level, but this is acceptable. We simply monitor the amount of fly ash in the tank; there is no need for control mechanisms. Since we are not familiar with your production process, we’re not sure whether continuous measurement is necessary. If it is required, it seems that weight hammers or weighing systems would be more practical options. Nuclear radiation detection methods require strict conditions, and in some cases those conditions aren’t met, making installation inconvenient
If the jar isn’t very large, weight can be used as a measurement
The weight-based method can be modified to work
