I. overview of products

The external ultrasonic liquid level switch is a new type of liquid level measuring and alarming device.. Is mainly used for monitoring the tank liquid level and achieve the upper limit and lower limit of liquid level in tank alarm or monitoring of pipeline is the presence of liquid (dry state protection), this technique overcomes the demanding requirements of the traditional measurement of medium or environment without dielectric constant, medium density, electrical conductivity, emission coefficient, pressure, temperature and precipitation factors influence, especially suitable for in the petroleum, chemical, pharmaceutical, power, food and other industries of various kinds of liquid level control. For high pressure, highly toxic, strong corrosion, dangerous chemicals liquid detection, our products is your ideal choice.

Two, working principle

The ultrasonic measuring principle, using our special sensor probe and between the tank wall transfer coupling theory of signal coupling, combined with the intensity of the acoustic signal sensor receiver, according to its own special DSP level and analysis of the algorithm, and can accurately determine when the front position level state.

Three, product features

(1) total non-contact measurement;

(2) the installation opening, do not stop, not clear, without fire, the tank can be installed in the normal operation conditions;

(3) it is especially suitable for measuring the liquid under high temperature, high pressure, corrosive, highly toxic and flammable environment.;

(4) the instrument has high accuracy, stable performance, high sensitivity, long life and anti-jamming..
