Magnetostrictive Level gauge for 50 to 20000mm
The Magnetostrictive Level Gauge is a high-precision solution designed for continuous liquid level and interface measurement in demanding industrial environments. Based on proven magnetostrictive technology, it delivers stable, repeatable and highly accurate measurement results over long-term operation.
This level gauge is particularly suitable for storage tanks, pressure vessels and process applications where reliable level data is critical for safety, inventory management and process control. By directly measuring the position of the magnetic float through time-of-flight detection along the waveguide, the system provides real-time level information that is unaffected by changes in temperature, pressure, density or electrical properties of the medium.
With its robust mechanical structure and flexible configuration options, the magnetostrictive level gauge supports both single liquid level and oil–water interface measurement in the same tank. Multiple output signals and communication protocols allow seamless integration into DCS, PLC and SCADA systems, making it an ideal choice for modern industrial automation.
Designed from a manufacturer’s perspective, the instrument can be customized in measuring length, materials, process connections and signal outputs to match specific application requirements. It is widely applied in oil & gas, chemical, petrochemical, power and tank farm systems where accuracy, reliability and long service life are essential.
