Abstract: fter the initial calibration of EuroLoop a comparison between the EuroLoop and Trapil facilities was performed using an 8 7 path ultrasoni c flow meter. Both labs find calibration results in a band of 0.15%. The curves obtained with different products connect well in the Reynolds domain . However in the range of 1000 Re 10000 there are significant differences of the deviations obtained wi th different liquids. As a first step of the evaluation of the Reynolds compensation in the meter, the calibrations will be repeated with EuroLoops big piston prover. The normalized difference of the two labs was evaluated at 31 Reynolds numbers between Re 1000 and Re 3000000. 16 values are smaller than 0.5 and 4 are bigger than 1. The h igh est values are observed around Re 10000 where significant differences are found between the calibrati on p oi nt s ob ta in ed w it h di ff er en t li qu id s.
