It is usually used to measure liquid level or material level in places where the temperature is between -40 degree and 95 degree and the pressure is below 3Bar (5kg/cm2). In the case of normal temperature and normal pressure, it is the best choice to choose ultrasonic level meter to measure liquid level. It has the characteristics of easy installation, long service life, maintenance-free, and has a relative price advantage. Since the ultrasonic level gauge does not contact the measured medium when measuring the level, and is a fully enclosed anti-corrosion structure, it is suitable for liquid level measurement of viscous, corrosive, turbid and other liquids.
