RADAR LEVEL RECORDER
RLR-0001-1, RLR-0003-1

FEATURES

	High Accuracy - 0.01 ft.
	Range - 60 ft.
	Integrated Antenna
Sutron’s Radar Level Gauge/Recorders are self-contained, precision devices for measuring stages (water level) without direct contact with the water surface. The Radar Level Recorder is ideally suited for making measurements in rivers, streams, reservoirs, tidal, oceans and industrial areas where the sensor can be located above the water surface. Using a special pulse-echo measurement technique, the radar has a range of 60 ft. Sutron offers both FCC and NTIA versions of the Radar. The FCC versions are available for any commercial or government agency in need of the device. This version has an FCC ID and is available for installation anywhere it is needed as an FCC part 15 device. The NTIA version is available only to US government agencies and for use outside the US. US government agencies who need to use this version must have it approved for operation by their own frequency coordinators. Both radars offer similar performance; however, the NTIA version does have increased signal to noise for quicker measurements and better performance with rough water. The Radar comes in several different models. The RLR-0001-1 (NTIA only) combines into a single package radar, antenna, keypad, display, permanent log, SDI-12 interface, RS232 interface. The RLR-0001-1 is packaged in a sealed enclosure. However, the enclosure is not rugged enough to be installed outdoors without additional protection. The RLR-0003-1 (FCC and NTIA) is an integrated unit without display. The enclosure is rugged and can be installed outdoors without additional protection. All the electronics for the radar are housed in the antenna enclosure. A 25 foot long cable provides both RS232 and SDI-12 interfaces to the radar.
