Magnetostrictive liquid level sensors play a role in precision in petrochemical storage

In petrochemical storage tank farms, where accuracy, reliability, and safety are paramount, precise liquid level monitoring is a non - negotiable requirement. As environmental regulations tighten and storage complexity increases, traditional level sensing technologies often fall short. This is where the magnetostrictive liquid level sensor—as developed by Shenzhen Soway Technology Development Co., Ltd.—emerges as a superior solution. Shenzhen Soway Technology Development Co., Ltd. is a professional manufacturer of magnetostrictive liquid level sensors. These advanced sensors offer a blend of high - resolution measurement, excellent repeatability, and real - time feedback capabilities that make them ideal for use in critical petrochemical environments.

Why Magnetostrictive Technology Matters in Petrochemical Tank Farms

The magnetostrictive principle offers distinct advantages for high - value, volatile, or hazardous liquid storage—common in petrochemical facilities. Inside each sensor, a waveguide runs along the length of the probe. A float containing a permanent magnet moves with the liquid surface, and a precisely timed current pulse is sent down the waveguide. The interaction between the current pulse and magnetic field generates a torsional wave, which travels back and is measured to determine the float’s exact position.

This non - contact method delivers millimeter - level resolution and repeatability even in harsh, pressurized, or chemically aggressive environments.

Key Benefits of Magnetostrictive Liquid Level Sensors for Petrochemical Applications

-High Accuracy and Stability: Soway’s magnetostrictive sensors achieve resolutions up to 0.01 mm, essential for monitoring refined oil, chemical intermediates, and LPG levels.

-Explosion - Proof Options: Intrinsically safe versions ensure compliance with hazardous area standards—vital for monitoring volatile compounds.

-No Drift Over Time: Unlike capacitive or ultrasonic sensors, magnetostrictive sensors maintain long - term stability with virtually zero signal drift.

-Temperature and Pressure Resistance: Stainless steel housings and hermetic sealing allow deployment in tanks that operate under high temperature and pressure.

Real - Time Monitoring for Operational Safety and Efficiency

In large - scale tank farms, knowing the exact level of each tank in real time enables better inventory control, prevents overfilling, and supports leak detection protocols. With Soway’s magnetostrictive liquid level sensors, plant operators gain access to:

-Dual - level measurement (e.g., oil - water interface)

-4–20 mA, RS485, and Modbus output options for system integration

-Remote diagnostics and maintenance alerts

-Alarm triggers for high / low level thresholds

This level of integration is particularly useful in centralized control rooms, where hundreds of tanks must be monitored continuously. Soway’s sensors can be installed across vertical or horizontal tanks, in both underground and above - ground configurations.
