    • Ultrasonic Liquid Level Transmitter with Reflective Technology™ measures reliably with condensation
    • Offered in 6m (19.6’) and 12m (39.3’) measurement ranges
    • Corrosion resistant PVDF transducer with IP68 PP enclosure
    • Fail-safe diagnostics with selectable signal fail-safe outputs
    • LCD display indicates level in inches, meters or percent of span
    • Narrow 3” (7.6cm) beam width for applications with limited space
    • Windowed enclosure cap provides liquid tight level indication
    • Configuration via push button display or LVCN414-SW software
    • Automatic temperature compensation from -40º to 80º C.

      • The LVU700 Series general purpose reflective ultrasonic level transmitter provides continuous level measurement up to 39.3’ (12m) with a 4-20 mA analog signal output and is configured via its integral push button display module or LVCN414-SW software. The non-contact liquid level sensor features our proprietary Reflective Technology™ that delivers reliable level measurement in condensing environments. Select this sensor for bulk tanks with chemicals, water, wastewater and oil (non-foaming and/or highly vaporous liquids). Typical applications include bulk storage, neutralization tank, clarifier 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 45º reflector, delivering reliable level measurement.

      Applications:Bulk storage, neutralization tanks, clarifier and waste sumps

      Configuration: In addition to the push button display module, the sensor may be configured via our LVCN414-SW software and one Fob USB adapter. LVCN414-SW is a PC utility program that allows users to easily configure their sensors, update firmware, save configurations and print wiring schematics prior to installation. LVCN414-SW is a free download from our website.
