The Department consists of the calibration laboratory, activities of which are calibration of cup-type and propeller-type current meters (in accordance with ISO 2537) and other hydrometric devices (electromagnetic and ultrasonic), which can be calibrated according to ISO 3455. Nominal water temperature for calibration is 1–26 ºC. Range of water flow velocity v is 0.02–7.00 m/s. CCSCM provides calibrations in accordance with International Standards ISO 3455:2007 Hydrometry – Calibration of current-meters in straight open tanks, and ISO 2537:2007 Hydrometry – Rotating-element current-meters respectively.
The detailed information on the calibration laboratory can be found on separate web of CCSCM.
Department Activities
Department Activities
In compliance with Organizational Code of TGM WRI, p.r.i., the Department carries out activities and applies to spheres of interest as follows:
- operation of CCSCM in compliance with the international standard ISO 3455,
- use of the calibration tank for research activities and experiments.
The Department provides the activities listed in the deed of foundation as follows:
- 9.36 operation of the calibration centre of hydraulic measurements,
- 9.37 performance of the centre for assessing eligibility for calibration of working gauges of the free surface water discharge,
- 9.38 performance of the calibration facility of working gauges of the free surface water discharge.
Czech Calibration Station of Current Meters (CCSCM) has been in continuous operation since 1930. The big experimental tank is fed by water from the navigational canal of the Troja weir and it passes through the area of T. G. Masaryk Water Research Institute (WRIM) in a north-south direction. It has total length of 224 m and bottom slope. It consists of intake, equalizing part with a double sided weir for keeping the water level constant, calibration tank proper, outflow part (measuring tank) and outlet into the canal. Calibration part of the tank (calibration tank) is determined by the section between sluice gate II and sluice gate III, between which the mutual distance is of 164 m. It has vertical walls, constant width of 2.5 m and bottom in a slight slope of 0.4 per mille. Working section of the calibration tank has the length of 138.6 m and water depth of 1.8 m.
The calibration tank can be used for other experimental activity – for example the research of the Czech Technical University in Prague, focused on the analysis of flood risks for pedestrians moving in the flood area, was conducted there.
