Flowline, UG12-0011-01, EchoPod Reflective Ultrasonic Liquid Level Transmitter, 12 m. (39.3') Sensor Range, 3" G Process Mount with FOB Adapter. Features: Offered in 12 m. (39.3') measurement ranges; Reflective Technology measures reliably with condensation; Corrosion resistant PVDF transducer with IP68 PP enclosure; Fail-safe diagnostics with selectable signal fail-safe outputs; LCD display indicates level in inches, meters or percent of span; Narrow 3" (7.6 cm.) beam width for applications with limited space; Windowed enclosure cap provides liquid tight level indication; Automatic temperature compensation from -40° to 80° C. Applications: The general purpose reflective ultrasonic level transmitter provides continuous level measurement up to 39.3' (12 m.) with a 4-20 mA analog signal output. The non-contact liquid level sensor features proprietary Reflective Technology that delivers reliable level measurement in condensing environments. Select this sensor for bulk tanks with non-foaming or highly vaporous media such as chemicals, water, wastewater and oil. Typical applications include bulk storage, neutralization tank, clarifier and waste sumps. Reflective: 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 45° reflector, delivering reliable level measurement. Thanks gravity.
