Maintenance of the large water reservoir of LNEC's Metrological Hydraulics Laboratory

LNEC, as Portuguese Designated Institute for the measurement of liquid flow and flow velocity, has a reference infrastructure in its Metrological Hydraulics Laboratory (UHM), where there is a large water reservoir (360 m3) that feeds the bench for testing and calibration.

Every five years this reservoir undergoes periodic maintenance, intended to assure the water quality in a closed circuit using filtration and treatment systems that contribute to reducing the environmental impact associated with this use. 

This maintenance activity that took place recently allows sharing rare images of this important infrastructure component.
