Typically, the presence of condensation substantially degrades the measurement signal strength of ultrasonic sensors, but new EchoTouch reflective ultrasonic liquid-level sensors (photo) work in areas with condensation. By orienting the transducer vertically, condensation runs off the unimpeded transducer face to deliver reliable level measurement, says the manufacturer. EchoTouch reflective-ultrasonic level transmitters are offered in small and bulk-tank versions with optional pushbutton display or software configuration, as well as HART communication options. — Flowline, Inc., Los Alamitos, Calif.
