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.
