EchoTouch® US01 & US03 Reflective Ultrasonic Liquid Level Sensor Transmitter
The intrinsically safe reflective ultrasonic level transmitter provides continuous level measurement up to 9.8’ (3m) with a 4-20 mA analog signal output, and is configured via our WebCal software. The non-contact liquid level sensor features our proprietary Reflective Technology™ that delivers reliable level measurement in condensing environments. Select this sensor for small tanks with non-foaming and mildly vaporous media such as chemicals, water, wastewater and oil. Typical applications include day tank, IBC or drum, cooling tower, skid or machine, process tank and waste sumps.
