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.
Fob USB Adapter LVU500-USB for programming LVU500 or LVU700 Series Level Transmitters.

Can this be mounted horizontally or vertically? Or does it need to be one way?
Asked by: DrPerry
Thank you for your inquiry about the reflective level sensor. It mounts in the vertical positin where the beam points down into the tank towards the liquid.

I see there's a beam width of 6" for the LVU712 model. Is there a beam angle as well?
Asked by: schori23
Thank you for your inquiry for this level sensor. It is a beam width, no angle.

Hello, I was wondering if this sensor has to be recalibrated or replaced after a certain amount of time?
Asked by: Jenny2
Thank you for your inquiry! There is no set timeline for re-calibration or replacement of these ultrasonic units. The programming is performed by entering the dimensions in the software with the device connected using the supplied USB. If readings appear off, the settings in the software should be checked and adjusted.
