Installation and selection
- Direct the radar beam towards the water flow. The documented installation angle is 30–45°, with 30° recommended.
- Review surface texture, turbulence, sensor height and obstructions before specifying the usable measurement range.
- Surface velocity is one input to discharge calculation; channel geometry, water level and site calibration are needed for flow volume.

Frequently asked questions
Does a surface-velocity reading give me the water volume?
Surface velocity is one input. Discharge calculation also needs channel geometry, water level and a validated relationship for the site. Check that relationship against field measurements before using a calculated flow volume for water allocation.
Where should the sensor be mounted?
Mount it above the water with the radar beam directed towards the flow. The source document gives a 30–45° installation angle, with 30° recommended. Review sensor height, water-surface conditions and obstructions before defining the usable range.
What should I provide when requesting a quote for the Radar Surface Velocity Sensor?
Channel dimensions and water-level variation; Expected surface velocity and flow direction; Sensor height and mounting angle; RTU interface, supply and cable route
Where can I compare available model options?
Open the Irrigation canal measurement guide linked on this page. Use it to compare equipment options before requesting a configuration.
Will it work with my existing system?
Check the field signal, supply, protocol and receiving platform against the selected model. The connection options listed on this page are a starting point; send your equipment model or interface document so we can check the combination before ordering.
