Magnetostrictive liquid level sensor, a kind of instrument for measurement of liquid level, is worked out on the basis of combined use of many technologies such as magnetostriction, flotage principle, electromagnetism induction and electron-technique. The measure instrument has many specialties, such as the error is tinier, the reading is righter, the range of measure is broader, the maintenance and useness is very convenient. As compared with common liquid level sensors, this kind of sensor has a lot of special advantages for high-precise measurement of liquid level.
