1) This is not the vertical distance to the water surface, but the distance to the water surface along the extended sensor axis.

2) Maximum permissible vertical distance to the water surface at an angle of inclination of 45°. For other angles of inclination, the maximum permissible distance is calculated as follows: hmax = 20 m x sin (angle of inclination)
