Stalker Surface Velocity Sensor

How to choose Sensors

Sets a new standard in OEM waterflow management

The Stalker Speed Sensor SVR is the ideal solution for OEM projects where accurate, reliable water flow measurement is a primary requirement. Backed by nearly two decades experience in microwave radar and 22 radar-related patents, the Speed Sensor SVR is self-contained in a waterproof enclosure and only needs 12 VDC to operate.

Ideally Suited for Water Flow Measurement
The Speed Sensor SVR features a rugged cast-metal exterior and the world’s most sensitive transmitter/receiver as well as miniaturized and modernized electronics. Its direction sensing software and updated algorithms position the Speed Sensor SVR as a new-generation radar ideal for the task of accurate and reliable water flow measurement. Moreover, the Speed Sensor SVR’s Ka Band performance measuring water flow is superior to the K Band used by some of its competitors’ radars.

User Adjustable Tilt Compensation
To make it better suited for measuring from elevated perspectives, the Speed Sensor SVR can be easily adjusted by the end user to compensate its speed reading based on the angle that the radar points at the target flow.

Wide Speed Range & Settings
The Speed Sensor SVR has a speed range of 0.2 m/s to 18.0 m/s – from below 1 mph to over 40 mph – with an accuracy of ±0.1 m/s. And it measures in meters/second, feet/second, miles per hour, and kilometers per hour.

Software Upgradeable
Utilizing a state-of-the-art Digital Signal Processor (DSP), the Speed Sensor SVR provides a level of performance, convenience, and accuracy previously unavailable. The DSP performs the critical filtering and timing functions required for speed measurement in its software, as opposed to hardware. This provides less unit-to-unit variation, more reliable performance, and easier maintenance. One unique feature is that it can be upgraded in the future by simply installing new software, preventing obsolescence!

And a Lot More
Adjustable tilt compensation, settings’ range, and DSP, combined with direction sensitivity, and 4 levels of sensitivity all make the Speed Sensor SVR the new standard in water flow measurement.
