Abstract
Centre for Metrology MIKES has gravimetric national
standard and also two closed type devices, named as D500
and D100, for water flow calibrations in Finland. These
calibration rigs are based on reference meters. Flow rate
in the D500 rig is possible up to 2700 m³/h and it has an
electromagnetic reference meters size of DN500 and DN150.
The D100 contains Coriolis flow meters as a reference
meter and their size are DN50 and DN15. Lowest
measurement uncertainty is 0.3% (k = 2) for both rigs.
Laser Doppler Velocimetry measurements have been done in
the D500 rig to verify the proper flow profiles between
the meter under test and the reference meter. This
presentation will show in detail the results, the
construction and the performance of the calibration rigs.
