A new non-contact surface velocity radar (SVR) sensor that dramatically improves the simplicity and reliability of stream, river and open channel measurements has been launched by
OTT Hydromet. Located safely above the water flow, the instrument is protected from the harmful effects of storms and floods, and can be easily integrated into a remote monitoring system.
A number of key features have been incorporated into the SVR 100, some of which are unique. Employing a highly accurate radar for non-contact operation the instrument also includes sensors for detecting potential sources of error. Measurement reliability is validated by meta data from an integrated sensor that detects the effects of bridge vibration from wind or vehicles, and another which monitors the angle of the SVR 100 to the water surface. With IP68 rating, it is extremely rugged and would even survive complete immersion.
Compact and lightweight the SVR 100 is quick and easy to install in unobtrusive locations, with no requirement for staff to enter the water, which saves time and money. Once installed, the SVR 100 operates on extremely low power with no ongoing requirement for calibration or maintenance. The addition of a level sensor and a datalogger enables the onsite computation of discharge, with multiple telemetry options.
The main advantage of the SVR 100 is its ability to measure accurately and reliably across a wide range of conditions, but especially during severe weather when there is a risk of flooding.
