High Accuracy Application Widely Integrated Ultrasonic Level Meter Non Contact Detail Introduction :
Liquid level measurement in various industrial fields, especially water treatment industry.
The integrated ultrasonic level meter is a new type of level switch.
The working principle of the ultrasonic level meter is that the high frequency ultrasonic pulse sent by the transducer (probe) meets the surface of the measured medium and is reflected back.
Part of the reflected echo is received by the same transducer and converted into an electrical signal. Ultrasonic pulses propagate at the speed of sound waves, and the time interval from emission to reception of the ultrasonic pulses is proportional to the distance from the transducer to the surface of the measured medium.
The relationship between the distance value S and the speed of sound C and the transmission time T can be expressed by the formula: S=CxT/2. Because the transmitted ultrasonic pulse has a certain width, the reflected wave and the transmitted wave in a small area close to the transducer overlap, which cannot be identified and the distance value cannot be measured.
This area is called the measurement dead zone. The size of the blind zone is related to the model of the ultrasonic level meter.
◆ Adopting advanced microprocessor and unique Echo Discovery echo processing technology, suitable for various complex working conditions
◆ The "false echo learning" function can correctly confirm the true echo and obtain accurate measurement results
◆ The transducer has a built-in temperature sensor, which can realize the temperature compensation of the measured value
◆ Adopt the patented technology of best acoustic matching to improve the signal strength and realize accurate measurement
