REFLECTIVE TECHNOLOGY
Condensation is the most common variable in liquid level applications. 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.
