Magnetostrictive Level Sensor adopts the principle of magnetostriction and is an intelligent multi-parameter liquid level meter specially developed for oil storage and transportation management and refining. Magnetostrictive Level Sensors can measure the temperature of multiple interfaces and storage liquids.
The liquid level sensor specially used for gas stations is the Magnetostrictive Level Sensor. If it is an underground oil tank, a Magnetostrictive Level Sensor is installed inside the oil storage tank. The oil level is directly displayed on the liquid level monitor. No manual measurement is required, and the oil quantity monitoring of multiple oil tanks can be realized remotely.

How does a magnetostrictive level sensor work?
The core sensitive element (waveguide wire) of the magnetostrictive sensor is a rare earth super magnetostrictive material. It has the advantages of high strain value and strong electrical (magnetic)—–mechanical wave conversion ability. It can convert small magnetic field vector changes into mechanical waves.
The sensor consists of three parts: an electronic probe, a stainless steel rod (built-in rare earth supermagnetic stretchable wire) and a floating ball (built-in magnet).
When the electric pulse generated by the pulse generator in the electronic probe is transmitted along the waveguide wire in the steel pipe, the electric pulse is accompanied by a ring-shaped magnetic field perpendicular to the waveguide wire that is transmitted along the waveguide wire at the speed of light.
When the electric pulse ring magnetic field meets the float’s inherent magnetic field, the magnetic field vectors of the two are superimposed to form a spiral magnetic field. Instantaneous torque is generated and a mechanical torsion wave is formed on the waveguide wire and transmitted back to the electronic probe at a certain speed, causing induction pulses to be generated at both ends of the coil.
By measuring the time difference between the triggering electrical pulse and the induction pulse generated by the return of the torsion wave, the measured liquid level height can be calculated. The temperature sensor embedded in the measuring rod can measure the temperature of the medium.
Diesel-Fuel-Oil Level Monitoring System
Liquid level monitoring can be achieved by configuring an intelligent liquid level monitor for one or more magnetostrictive level sensors. Here we take the oil level monitoring system of a gas station as an example to introduce it.
The intelligent liquid level management system of gas stations is an intelligent system that measures the liquid level, capacity and other data in oil tanks and storage tanks, and manages the daily import, sales and storage of gas stations.
The gas station intelligent liquid level management system consists of intelligent magnetostrictive probes, intelligent monitors, explosion-proof data display screens and liquid level measurement system software.
The probe uses magnetostrictive technology and can measure the oil level, water level and real-time temperature in the oil tank;
The intelligent monitor automatically collects and processes probe data, and uses scientific calculation methods to provide gas stations with a complete management plan for the purchase, sale and storage of oil products.
