INSTALLATION POSITION
Ensure the selected site and radar paths meets the criteria as described in Sections 3.1 and 3.2.
The minimum mounting height above the water’s surface is 0.2 m; however, it is recommended to
mount the sensor from 0.5 m – 15 m above the water’s surface. Sensor should be mounted on a
vertical pole with inclination tolerance of ±5° to the vertical plane reference.
Figure 3-2: Installation Position
For optimal operation and results, the velocity sensor should be pointed directly upstream, so that
the water flows towards the instrument and with the radar beam parallel with the water flow (see
Figure 3-3). Any deviation from the parallel water flow direction will introduce an offset to the
measurement value and the measured value will be lower than the actual surface velocity of the
water.
