the services concern: 1-supply of a new mobile gauging unit: new utility vehicle with a GVW <3.5t equipped with a system for gauging the flow of watercourses by immersion of a salmon whose reel measures the speed of flow of water, from the surface to the bottom, and this on several verticals over the entire width of the watercourse. These measurements are then processed by embedded software to establish the flow rate on the measurement section. This vehicle will include facilities (storage lockers, worktop, etc .) and equipment (generator, deployable projectors for night gauging, etc.) specified to the CCTP. 2 - upgrading by the contract holder of two old tonnage units already in service according to the specifications of the new unit, in particular for fittings and equipment
