The LVU500 Series general purpose reflective ultrasonic multi-function level transmitter provides continuous level measurement up to 3 m (9.8) with a 4-20 mA analog signal output and four relays and is configured via web calibration software. The non-contact liquid level sensor features our proprietary Reflective Technology® that delivers reliable level measurement in condensing environments. Each relay can be configured for alarm, automatic fill or empty functions. Select this sensor for small tanks with chemicals, water, wastewater and oil (non-foaming and/or highly vaporous liquids). Typical applications include day tank, IBC or drum, cooling tower, skid or machine, process tank and waste sumps.

Reflective Technology ®

Condensation is the most common issue for ultrasonic level transmitters. Condensation attenuates the acoustic signal of ultrasonic sensors with horizontal transducers, weakening their signal strength and signal to noise ratio by up to 50%, and substantially reducing their measurement reliability. At the core of Reflective Technology® is a simple fact. Unlike flat horizontal surfaces, significant water droplets cannot adhere to smooth vertical surfaces. By orienting the transducer vertically, condensation runs off the transducer and does not affect sensor performance. The unimpeded transmit and receive signals are redirected to and from the liquid off a 45 º reflector, delivering reliable level measurement.

Applications:
Day tank, skid or machine, cooling tower, IBC or drum, process tank, small waste sump

Configuration:
The sensor is configured via our WebCal software and one Fob USB adapter. WebCal is a PC utility program that allows users to easily configure their sensors, update firmware, save configurations and print wiring schematics prior to installation. WebCal is a free download from our website.
