Applications of Vibrating Rod Level Switch and Radar Level Meter in a Thermal Power Plant

Project overview:

A renovation project in a thermal power plant in Shandong was to regularly discharge slag and furnace ash in thermal power boiler system to ensure its working efficiency. Level meters were needed during the process to detect and control the level of slag and furnace ash. The comparison between heavy hammer material level meter and RF admittance level switch shows that problem of buried hammer often happens if heavy hammer material level meter is used and false alarm or probe being bent often happens because of material buildup if RF admittance level switch is used. Jiwei Radar Level Meter and Vibrating Rod Level Switch won the tender of the project in their excellent performance and quality.

Selected products:

Jiwei Rada-22 Radar Level Meter, Jiwei Vibrating Rod Level Switch

Features of the products: 

1.  Rada-22 High Frequency Pulse Radar Level Meter

Rada-22 is made of high quality modules from Siemens and with false echo suppression function to eliminate fixed disturbance. LUI display makes trouble diagnosis easier. It is with multiple echo processing algorithms which are programmable for a variety of complicated conditions.

2. Tube-11 Vibrating Rod Level Switch

Tube-11 is a first made-in-China Vibrating Rod Level Switch that designed with double vibration tubes. It has high sensitivity, can effectively prevent material buildup and avoid false alarm. The minimum measurable density can be as low as 0.02g/cm³, suitable for a majority of granular solids. For high temperature applications, the process temperature can be up to 400℃. It can be used for either DC or AC conditions. It is easy to install and no calibration is required.

Performance:

Both of products have been running well with accurate level measurement in the thermal power plant in Shandong. No false alarm has happened. Its easy installation, safety of operation and high reliability won the customer’s trust. After revisiting, the customer gave Jiwei very positive feedback and praises. The user said:“Honestly, I heard about Jiwei from my friend. He recommended Jiwei´s products to me because of its high quality. I was hesitated at the beginning. But after having tried it for quite some time, I definitely believe now Jiwei´s products are really reliable, and comparable to imported brands.”
