The EchoTouch™ is an ultrasonic transmitter that provides non-contact level measurement. This transmitter is available in two models: two-wire (LU20) or three-wire (LU30). Both have an LED display (in inches or cm), easy calibration using simple push buttons, and are well-suited for challenging media, although the LU20 is instrinsically safe for especially difficult liquids.
