Condensation is the most common variable in liquid level applications, and it substantially degrades the measurement signal strength of ultrasonic sensors, until now. New reflective-ultrasonic level sensors work in condensation. By orienting the transducer vertically, condensation runs off the unimpeded transducer face to deliver reliable level measurement. EchoPod reflective-ultrasonic level transmitters are offered in small and bulk tank versions with optional relay control, push button display or software configuration.
