ultrasonic thermometer is controlled by microprocessor digital material level meter, the measurement of pulse ultrasonic wave by sensors ( Transducer) , the sound waves reflected an object's surface by the same sensor after receiving, converted to electrical signals.

but in some special circumstances, also have to choose double probe solutions, such as the detection distance is far away, in order to guarantee a certain sensitivity, must increase the transmission power, with high power transducer, but these high-power transducer as receiving detector sensitivity is very low, even can't used to receive. In this case, have to the other with a high sensitivity receiving detector.

in the case of normal temperature, atmospheric pressure, the choice of ultrasonic level meter to measure the liquid level is the best choice, has reliable operation, easy installation, use cycle is long, the characteristics of free maintenance, and has a relative price advantage. Due to the ultrasonic level meter in the measurement of material level, do not contact with measured medium, for all airtight anti-corrosion structure at the same time, so for sticky and corrosive, cloudy all kinds of liquid level measurement, best effect. For liquid liquid level of volatility, the advantage is transmitted power is larger, in non-contact level measurement instrument, make full use of the instrument to measure the performance.

working frequency of ultrasonic level meter and measure performance: high frequency (sensor 40 - 70千赫) Work, sensor size, blind area is small, good directionality, high precision, fast, but its acoustic attenuation transmission medium ( Air) Poor fluctuate penetrating, range is small. Due to the popularization and development of radar technology and radar technology characteristic, in the material level measurement, ultrasonic thermometer has a tendency to be replaced by radar level meter. Cost-effective integrated analysis, in terms of level measurement, ultrasonic thermometer and the market.
