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.
Features & Benefits
