AA meter set up in cable car

Essential gear for measuring streamflow above large rivers. Within this cable car a reel connects to a Price AA flowmeter and sounding weight. Hydrologic technicians reel down the weight until they hit the river bottom, input the total depth into the AquaCalc, then they measure the flow within the water column at various depths to best capture water velocities. Measurements are taken at multiple sections across the channel to get the total flow volume at cubic feet per second.
