By detecting inclination without the use of shafts it is possible to capture the position of movable weir flaps or other movable and inclinable components such as sluice boards or slide valves without any problems. Overflow volumes or other flow volumes thus can be easily determined by using a Q/h relation or detected angles. Existing weir flaps can be easily retrofitted by installing the unit on the inclined plane.

NDW 2 combines high accuracy and operational safety with robust design.
The compact unit is free of wear since the measurement principle does not use any movable parts and hence provides reliable measurement results even under flood conditions (IP68).

NDW 2 provides a 4 - 20 mA signal proportional to the angle of inclination (0 - 90° or 0 - 60°) to obtain overflow data.

Following devices such as HydraulicCalculator 2 use flap-specific data to compute accurate overflow volumes.
