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.
