204 pieces of Jiwei Flame-proof Tuning Fork Liquid Level Switches have been operating stably and reliably for more than 5 years without any problems or failures

Jiwei Rotary Paddle Switches have successfully won the bid in some waste incineration power generation projects.

Fork-11 Ultra-high Temperature Tuning Fork Level Switch is featured with the function of water cooling (air cooling) and is able to work reliably under ultra-high temperature conditions that up to 400℃.

Vibrating fork level switches are ideal for pipeline liquid level measurement because of its compact tines. But what are the installation skills for vertical pipeline?

Ring-11 Liquid Level Switch has four optional outputs: relay output, two-wire system, NAMUR and transistor. It has also Passed SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety and Flameproof Enclosure explosion protection.

Aimed at the low mounting position and limited, Jiwei customized and re-structured Magnetic Level Indicators on the basis of the client’s requirements.

According to the suggestion, the client selects Uson-21 Flameproof Ultrasonic Level Transmitter with a measuring range of 10m. So far, all the sensors have been installed and fully operated.

　　After detailed communication with the client, Jiwei engineer recommended Tube-11 Vibrating Level Switch due to the large proportion of alumina particles and the strong magnetic field.

The user decided to replace all imported Siemens admittance level switches to Jiwei Cape-11R Rope Type Admittance Level Switches to measure the level of coal silos in the power plant.
