Flowline EchoTouch® US01 & US03 Reflective Ultrasonic Non-Contact Liquid Level Sensor Transmitter, 2 in. NPT, Intrinsically Safe

EchoTouch® US01 & US03 intrinsically safe reflective ultrasonic level transmitter provides continuous level measurement up to 9.8 ft. (3m) range with a 4-20 mA signal output and four relays, and is configured via Flowline's WebCal software. The non-contact liquid level sensor feature a proprietary Reflective Technology™ that delivers reliable measurement in condensing environments. The level sensor is suited for small tanks with non-foaming, non-condensing or high vapor media such as chemicals, oil, water and wastewater. Applications include day tank, IBC, drum, skid or machine, cooling tower, process tank and waste sumps.
