EchoTouch - Model US06 & US12 -Reflective Ultrasonic Liquid Level Transmitter
The intrinsically safe reflective ultrasonic level transmitter provides continuous level measurement up to 39.3’ (12m) with a 4-20 mA analog and HART digital signal output, and is configured via its integral push button display module or WebCal software. The non-contact liquid level sensor features our 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.
- Offered in 6m (19.6’) and 12m (39.3’) measurement ranges
- Reflective Technology™ measures reliably with condensation
- Corrosion resistant PVDF transducer with aluminum enclosure
- Narrow 3” (7.6cm) beam width for applications with limited space
- LCD display indicates level in inches, meters or percent of span
- HART communication in point to point and multi-drop modes
- Fail-safe diagnostics with selectable fail-safe signal outputs
- Configuration via push button display or WebCal software
- Automatic temperature compensation from -40º to 80º C.
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. Thanks gravity.
