The new ECHO Air Transducer is a complete line of ultrasonic level measurement transducers with all the electronics embedded inside. This evolution of ultrasonic technology removes the need for remote electronics, thus simplifying installations and saving money. Depending on the model, it can measure 0 to 132 ft and provide a 4-20mA output accurate to within +/- 0.25% of range. Visit WEFTEC Booth #1904 to see a demonstration.
