Flowline Level sensors are not affected by condensation

Condensation is the most common variable in liquid level applications. Condensation attenuates the acoustic signal of ultrasonic sensors with flat transducers, weakening their signal strength and signal to noise ratio by up to 50%, and substantially reducing their measurement reliability. 

At the core of the 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.
