The 3D EAU solution

Our device allows for easy verification of the water depth measurement in accordance with regulatory requirements.


Our device consists of:

- Commercially available products:  leveling rod, tripod, cross line laser
- 3D EAU products: target, supports for the leveling rod and the cross line laser

Measurement verification protocol

The target is aligned with the invert level of the overflow structure using the cross line laser in order to check the datum. The leveling rod is vertically translated to verify intermediate depths.
