To ensure stable production, Tuning Fork Level Switches are installed in the powder receiver to control the start-stop of pneumatic conveying system by outputting switch signals.

The stable and excellent performance of Ring-11s in the level measurement of white oil storage tanks further highlights the cost-effective.

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.

After test trial, the client replaced all the original liquid level switches to Jiwei Ring-11 Intrinsically Safe Tuning Fork Liquid Level Switch with NAMUR Output.

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 installing all Jiwei Flap-11 Magnetic Level Indicators, the clear visibility, strong sealing technique, stable performance, distance indication and easy maintenance have convinced the client.

Tube-11 Vibrating Rod Level Switch is designed with double vibrating tubes, which prevents bulk material from getting stuck or jammed.

Remote Transmitter is usually tied to measuring float and operated together with Magnetic Level Indicator. Through the remote transmission of liquid level signal to the control room in the form of 4-20mA current, the liquid level height can be controlled remotely in real time.

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.
