Testing the flow-measurement equipment at the outlet: The weir on the left is hydraulically coupled to the stilling well (lid off) and water level sensor in the centre. The Neon (mounted on top) converts water level, from the sensor below it, to flow rate. It also provides feedback for the gate controller (not visible) and enables remote access via a cellular network.(Martin Robertson, NIWA)
