Salient Characteristics S20123

NON-CONTACT RADAR LEVEL/VELOCITY/DISCHARGE SYSTEM

SALIENT CHARACTERISTICS:

1 EA, Non-Contact Radar:

1. Shall be capable of contact-free continuous measurement of water discharge using Doppler radar technology.

2. Shall be capable of measuring water velocity, water level, and water discharge.

3. Shall be capable of being installed on a bridge, or other structure, without expensive structural measures in the rivers or channels, thus allowing it to be located outside of the danger area during flood events.

4. Shall have a distance to water surface range to at least 35 m and be capable of detecting flow direction.

5. Shall measure water level with an accuracy of at least ±2 mm and a resolution of 1 mm.

6. Shall measure velocity over a range of 0.30 to at least 15 m/s and an accuracy of at least +/-0.01 m/s; +/- 1%.

7. Shall operate over a power range of 6 to at least 30VDC.

8. Shall recognize hysteresis effects.

9. Shall measure in back water.

10. Shall measure where weed growth prevails and sensor is not affected by turbidity.

11. Shall be able to endure harsh environments and be at least IP 67 compliant.

12. Shall perform over a temperature range of -35° to at least +60°C.

13. Shall provide integrated lightning protection.

14. Shall have a minimum of one (1) each interface for SDI-12, RS-485, and four (4) Analog outputs (4-20 mA).

15. Shall be capable of single measurement intervals of at least 8 seconds apart.

16. Shall have a radar frequency of at least 24 GHz (K-band).

17. Shall be capable of automatic vertical angle compensation with an accuracy of at least ±1° and resolution of at least ±0.1°.

18. Shall include a cable that is at least 10 m long.
