The SUMPI is an Ultrasonic Level Transmitter capable of measuring liquid and solid applications up to a range of 10m. The Transducer is fitted to the top of the silo or tank and faced down towards the material being measured.The microprocessor in the Transmitter fires an electronic pulse which the Transducer converts to an acoustic pulse. This pulse travels to the material and is reflected back from the material. The Transducer then converts this energy back into a signal and stops a counter in the microprocessor which then, knowing the speed of sound through air, can accurately determine the distance. The powerful software removes false echoes and the electronic filter removes ambient noises.
