Ultrasonic Level Transmitter

Principle
Ultrasonic pulses generated by the transducer(antenna)system, which travel at the speed of soundtoward the target medium, are reflected by the surface of medium and received by the transducer system again. Due to the fact that the measurable time lapse between pulse emission and receptionby antenna is proportional to the distance between antenna and highest level of target medium, the principle of ultrasonic level instrument can be illustrated as the following equation: S=CxT/2, S: Distance, C: Velocity of sound, T: Time lapse.

Features
Because of the certain bandwidth of pulses, the unidentifiable overlap between pulse Emissionand reception arises in specified zone extending downward from transducer face, which leads to thelevel measurement malfunction. Therefore this specified zone is called measurement blanking zone. The size of measurement blanking zone differs for different models of ultrasonic level instruments.

Thanks to the advanced microprocessor and unique EchoDiscovery echo processing Technology, the ultrasonic level instruments can be used under various complex conditions.

The false echo storage function assures that the instrument can detect the right echo even Withthe presence of multiple false echoes and present accurate measurement results eventually.

The built-in temperature sensor inside transducer can complete temperature compensation for measurement results.

Ultrasonic transducer has adopted best patented sonic matching technology, which helps It strengthen its emission power, enhance the signal intensity and eventually achieve accurate measurement.
