1. Check that the instrument is positioned properly
Make sure that the instrument is installed above the water surface, pointing
toward the water surface at a vertical angle. Recommended vertical angle is 45
degrees.
Make sure that the instrument is leveled and pointing towards the water surface
at the right angle (the radar beam should be perpendicular to the water surface).
Both tilt angles should be zero degrees, or not bigger than 2° in any direction.
2. Check that there are no obstructions between the instrument and the water
surface
There should be no obstructions between the instrument and the water surface,
so that the radar waves can freely travel from the instrument’s antenna to the
water surface and back. Objects such as rocks, construction elements (metal,
concrete, etc.), vegetation (tree branches, water vegetation, etc.) can all affect the
instrument’s reading.
If there are some minimal obstructions far away from the water surface, and the
radar is reporting the distance to these objects instead of the distance to the water
surface, you can adjust the active zone of the instrument. The active zone limits the
minimum and maximum range within which the instrument searches for the water
surface. For example, if there is an obstruction 1 meter away from the instrument,
and the instrument reports a distance of 1 meter, but the water surface is expected
to be between 3 and 5 meters, you can adjust the active zone to be within 3 and
5 meters, and then the instrument will discard all measurements outside of that
range.
