This contract is a framework agreement for the purchase of flow meters as part of operational flow measurement at the Hydrological Information Center of the Hydraulic Engineering Laboratory. At more than 40 locations, flow velocities are continuously measured with H-ADCP devices that display the average flow velocity every 10 seconds in various cells. These average flow velocities, together with the measured water level, are processed into discharges which are regularly calibrated to adjust to the best available discharges for the relevant stations every 5 to 15 minutes. Because the knowledge and quality of these discharges are very important for daily water management, we as the measurement service must try to minimize downtime and maintain the highest possible quality. In case of device failure, we must be able to install and recalibrate an equivalent alternative device within a few days. Therefore, we need to maintain a limited stock of several flow measurement devices and accessories and wish to implement standardization here.
