I. Product Overview posted outside the ultrasonic liquid level switch is Air Show from Xi'an Electronic Science and Technology Co., an independent research and development of a new type of level measurement alarm device. Monitoring the tank level is mainly used to realize the liquid level inside the tank or the upper and lower alarm monitoring whether liquid is present in the conduit (dry protection), this technology to overcome the traditional measurement of demanding media or environment without permittivity, dielectric density, electrical conductivity, emission coefficient, pressure, temperature, precipitation and other factors, especially for liquid level control in all types of petroleum, chemicals, medicine, electricity, food and other industries. For high pressure, a highly toxic, highly corrosive, the detection of liquid hazardous chemicals, our product is your ideal choice. Second, the principle use of sonar measurement principle, the use of the principles of our special transfer coupling the sensor probe and the tank wall is coupled between the signal conversion, combined sensor receives the acoustic signal strength, and analyzed according to their specific DSP algorithm level, and then can accurately determine the current level of state position. Third, the product features (1) completely non-contact measurement; (2) the installation is not cut, do not stop, clear tank, no flare, can be installed under normal operating conditions of production; (3) is particularly suitable for high temperature, high pressure, corrosion, there are measurements of various liquids under toxic and explosive environments; high (4) instrument precision, stable performance, responsive, long-life, anti-jamming.
