Sensor Tingkat Magnetostriktif
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.

Magnetostrictive Level Gauge Application – Storage Tank Level & Interface Measurement
Magnetostrictive level gauges are widely used for continuous liquid level and interface measurement in storage tanks and process vessels where high accuracy and long-term reliability are required.
In oil & gas, petrochemical and chemical industries, the gauge provides precise monitoring of liquid level and oil–water interface in crude oil tanks, product tanks, and separation vessels. Accurate level data helps prevent overfilling, optimize inventory management, and improve operational safety.
For tank farms and bulk storage systems, the magnetostrictive level gauge supports long measuring ranges and stable performance under varying temperature and pressure conditions. Maintenance-free operation reduces downtime and lowers total cost of ownership, making it a cost-effective solution for large-scale installations.
With flexible probe designs, corrosion-resistant materials, and multiple signal outputs, the instrument can be easily integrated into existing control systems, ensuring reliable operation in both new projects and retrofit applications.
Magnetostrictive Liquid Level Sensor-Working Principle
The transmitter sends a short excitation pulse along the magnetostrictive waveguide.
A magnetic float moves with the liquid level and generates a static magnetic field.
When the pulse reaches the float, a torsional wave is generated at that position.
The torsional wave travels back to the transmitter at a constant speed.
The time difference is calculated to determine the exact liquid level or interface position.
