OTT Hydromet OTT SVR 100 Surface Velocity Radar with factory preset SDI-12 interface 6315100490

The OTT SVR 100 is the ideal sensor to collect surface water velocity measurements without being installed in the water, for all the benefits of non-contact measurement. This simple and compact radar sensor with integrated SDI-12 interface provides data during floods or times of high suspended sediments. By being installed above the water, the sensor is safe from rising water levels or floating debris. Only the OTT SVR 100 has an ultra-compact mounting design with flexible angle of inclination for mounting vertically or horizontally with measurement quality and vibration index parameters. The sensor allows specialists like hydrologists and program managers to identify data influenced by sensor movement (e.g., wind, traffic) using meta data from integrated vibration and tilt sensors. The sensor easily integrates with new or existing systems using SDI-12 or SDI-12 (over RS-485). It is also compatible with OTT Prodis 2 software used for system calibration. Benefits Reduces number of field visits and total cost of ownership By mounting safely above the water surface away from floating debris and by having low-maintenance requirements, the sensor can remain operating uninterrupted for longer periods of time to save on unnecessary field visits and long-term costs. State-of-art measuring principle technology Oriented parallel to the main flow direction and tilted against the water surface, the sensor is transmitting and receiving electromagnetic waves. The sensor detects a change in frequency of returning signals if the water surface is rough and in motion (Doppler shift). From this the water surface velocity can be derived. A leading indicator to detect shifts in existing discharge rating curves If you have a rating curve based on flow meter or ADCP measurements and you are measuring continuous surface water velocity, you can use real measurements to verify the extrapolated part of the rating curve. Informs when instream velocity measurements may be required When a shift is detected, depending on the nature and extent of the shift, it can indicate when a field visit is necessary. This ultimately improves data quality by enabling fast response to changes.
