RiverSonde Equipment Specifications
The RiverSonde consists of antenna mounted onto single post, a transceiver and
processor unit.
Output Radiated Power: 1 watt
Operating Frequency Range: Select a band between 420-450 MHz
that radio frequency
license can be obtained for.
Bandwidth: up to 30 MHz (10 MHz => 15 meter range resolution,
30 MHz => 5
meter range resolution).
Power Requirements: either 120 VAC or 220 VAC, 50-60 Hz; approximately
100 watts for RiverSonde. 400 watts required if using optional weatherproof box
with cooling system. Additional power may be required onsite for any peripheral
equipment.
Communication link to system processor required for automated data retrieval,
remote system monitoring and support.
Internet Protocol preferred.
