Level Measurement Ultrasonic Level Transmitter Intellectualization PVC Material Non Contact Measurement
Ultrasonic Level Transmitter
Ultrasonic level meter is a digital level meter controlled by microprocessor. In the measurement of ultrasonic pulse made by sensor (transducer), sound waves after the liquid surface reflection by the same sensor receiving, by piezoelectric crystal is converted into electrical signals, and by sound waves between transmitting and receiving time to calculate the sensor to the measured distance on the surface of the liquid. Due to the use of non-contact measurement, the measured medium is almost unlimited, can be widely used in a variety of liquid and solid material height measurement.

Ultrasonic Level Transmitter Measurement Principle
The ultrasonic level meter is installed on the top of the container. Under the control of the electronic unit,the probe emits a beam of ultrasonic pulses to the object to be measured, the sound wave is reflected by the surface of the object, and part of the reflected echo is received by the probe and converted into an electrical signal, which is retransmitted according to the ultrasonic wave. The time difference to re-reception and the known speed of sound are used to determine the change of the material level. The microwave signal is processed by the electronic device and finally converted into an electrical signal related to the material level.
