A piezoelectric crystal inside the transducer mounted on top of the tank converts electrical pulses into sound energy that travels in the form of a wave at the established frequency and at a constant speed in a given medium. The sound waves are emitted in bursts and received back at the transducer as echoes. The Ultrasonic Level Measurement Instrument measures the time for the bursts to travel down to the reflecting surface and return. This time will be proportional to the distance from the transducer to the surface and can be used to determine the level in the tank. Ultrasonic systems are accurate within a range of approximately 8m. A typical installation consists of two parts: A Transducer, consisting of both a transmitter and receiver. Ultrasonic energy is transmitted from the í¦headí¦ in the direction of the liquid surface. When the ultrasonic waves contact the surface, they are reflected back to the receiver in the head. Electronics, which produce, control and time the ultrasonic pulses which are transmitted and received by the head. The electronics also transmit control signals to remote monitoring devices such as displays and process control systems.
