Explosion-Proof Magnetostrictive Level Gauge Float Level Gauge Level Transmitter
Magnetostrictive Liquid Level Meter
Magnetostrictive Liquid Level Meter Operating Principle
Magnetostrictive liquid level sensor (hereinafter referred to as sensor, including common type and flameproof type) is used for continuous measurement of liquid level and interface. In addition, magnetostrictive liquid level sensors are also widely used in various fields, including industrial measurement and control of liquid levels in various liquid tanks such as petroleum, storage of chemical raw materials, industrial processes, biochemistry, medicine, food and beverage, tank farm management and underground storage of gas stations, dam water level, reservoir water level monitoring and sewage treatment, etc.
Magnetostrictive level gauge consists of three parts: probe rod, circuit unit and float. To measure, the circuit unit generates pulses of current that travel down the magnetostrictive line and generate a circular magnetic field. A float is arranged outside the probe rod, and the float moves up and down along the probe rod with the change of liquid level. The float generates a magnetic field at the same time because it is fitted with a set of permanent magnets. When the current magnetic field meets the float magnetic field, it produces a "twisting" or "return" pulse. The time difference between the "return" pulse and the current pulse is converted into pulse signals to calculate the actual position of the float and measure the liquid level.

Magnetostrictive Liquid Level Meter Design Features
- More widely applicable, there are a variety of probe forms, a variety of process connection fbrms,a variety of manufacturing materials, customizable design.
- High reliability: because magnetostrictive liquid level gauge uses waveguide principle, no mechanical movable part, so no friction, no wear. The whole converter is enclosed in stainless steel tube and is not in contact with the measuring medium. The sensor works reliably and has a long life.
- High accuracy: because the magnetostrictive liquid level meter uses waveguide pulses to determine the measured displacement by measxiring the time between the initial pulse and the termination pulse, the measurement accuracy is high and the resolution is better than 0.01FS, This is an accuracy that is difficult to achieve with other sensors.
- Good safety: the magnetostrictive liquid level meter has high explosion-proof performance, intrinsically safe explosion-proof, safe use, especially suitable for chemical raw materials and flammable liquid measurement. It is not necessary to open the lid of the tank to avoid the insecurity of manual measurement.
- The magnetostrictive liquid level gauge is easy to install and maintain: the magnetostrictive liquid level meter is usually installed through the existing nozzle on the top of the tank. It is especially suitable for the installation of the underground storage tank and the storage tank that has been put into service, and can not affect normal production during the installation process.
