Tek-Sound 4200A Ultrasonic Level Transmitters are commonly used level measurement instruments used in several industries for the continuous measurement of the level and volume of different media in open and closed tanks and for flow measurement in open channels. They are a cost-effective, reliable, and accurate solution in a wide array of applications involving both solids and liquids. Since they are non-contact devices, they require minimal maintenance and suffer minimal wear and tear. Additionally, this also ensures that they can be used under difficult process conditions.
Measuring Principle
An ultrasonic transmitter measures the level of a medium based on the propagation time of sound waves between a transducer and the surface of the medium. It consists of a transducer with a piezoelectric crystal that converts the electrical energy generated by the transmitter into sound waves. These sound waves are transmitted towards the surface of the medium and reflected to the transducer where the piezoelectric crystal then converts them into an electrical signal. The transmitter measures the time taken by the waves to be emitted and reflected by the surface and return to the transducer. The distance between the transmitter and the medium surface is then calculated using the time of flight of the waves and the speed of sound.
