Features of Magnetostrictive Level Transmitter

When the sensor of the magnetostrictive level transmitter is working, the circuit part of the sensor will excite a pulse current on the waveguide wire. When the current propagates along the waveguide wire, a pulse current magnetic field will be generated around the waveguide wire. A float is provided outside the sensor measuring rod of the magnetostrictive liquid level transmitter, and this float can move up and down along with the changing of the liquid level along the measuring rod. Inside the float, there is a set of permanent magnetic rings.

Technical Advantages of Magnetostrictive Level Transmitter

  • Magnetostrictive level transmitter is suitable for the level measurement of clean liquid level with high precision requirements, the accuracy reaches 1mm, and the latest product accuracy can reach 0.1mm.

  • It can also be applied to the boundary measurement between two different liquids.

  • Explosion-proof design, suitable for dangerous occasions, the intelligent electronic circuit design can calculate the volume; the only movable part is afloat, and the maintenance is extremely low.

  • Magnetostrictive level gauges are used for industrial measurement and control of liquid levels in various liquid tanks such as petroleum, chemical raw material storage, industrial processes, biochemistry, medicine, food and beverage, tank farm management and gas station underground storage, dam water level, reservoir Water level monitoring and sewage treatment, etc.


Application of Magnetostrictive Level Transmitter

With the rapid development of science and technology, high and new technology has been widely used in various industries. High-tech magnetostrictive level sensors are used for liquid level measurement of various storage tanks. This type of liquid level instrument has the characteristics of high precision, strong environmental adaptability, and easy installation. 

Therefore, it is widely used in the field of liquid level measurement in petroleum, chemical industry, etc., and gradually replaces other traditional sensors and becomes the best in liquid level measurement.

The FEEJOY manufactured magnetostrictive level transmitters have been widely applied through out the industries, the China level transmitter manufacturer has integrated accurate, safe and reliable properties into the design of our magnetostrictive level indicators. 


Magnetostrictive Level Transmitter FAQs

What parts is magnetostrictive liquid level gauge composed of?

Detection rod, circuit unit and float. During the measurement, the circuit unit generates a current pulse, which is transmitted down the magnetostrictive line and generates a ring-shaped magnetic field.

Why Choose Feejoy's Magnetostrictive Level Transmitter?

Feejoy Technology's magnetostrictive liquid level gauge can measure the oil tank's liquid level and temperature, and can also measure the oil tank's leakage. The leak detection accuracy reaches 0.375 liters/hour, which can meet the needs of different users, to achieve a higher price-performance ratio.

What advantages does magnetostrictive level transmitter have when measuring the oil tank liquid level?
  • Strong reliability: Since the magnetostrictive liquid level gauge adopts the principle of the waveguide, there is no mechanical movable part, so there is no friction and no wear. The entire converter is enclosed in a stainless steel tube and is not in contact with the measurement medium. The sensor works reliably and has a long life.

  • High precision: Because the magnetostrictive liquid level gauge works with waveguide pulses, the measured displacement is determined by measuring the time of the start pulse and the end pulse during the work, so the measurement accuracy is high, and the resolution is better than 0.01% FS, which Accuracy that is difficult to achieve with other sensors.

  • Good safety: The magnetostrictive liquid level gauge has high explosion-proof performance, intrinsically safe explosion-proof, and is safe to use, especially suitable for the measurement of chemical raw materials and flammable liquids. It is not necessary to open the tank lid during measurement to avoid the unsafeness of manual measurement.

  • The magnetostrictive liquid level gauge is easy to install and maintain: the magnetostrictive liquid level gauge is generally installed through the existing nozzle on the top of the tank and is particularly suitable for the installation of underground storage tanks and operational storage tanks. The process does not affect normal production.

  • Facilitate system automation work: The secondary instrument of the magnetostrictive liquid level gauge adopts standard output signals, which is convenient for the computer to process the signal, and it is easy to realize networked work and improve the automation degree of the entire measurement system.
