Having access to 3 different flow meters, it was attempted to assess their measuring capabilities using water and liquid having complex rheological properties. To do so, a hydraulic system was performed, in which 3 flow meters, namely elbow, Coriolis and electromagnetic flow meters were connected in series. Measuring the pressure difference on the secant of the elbow flow meter was conducted using a liquid manometer and a PTD 0.1 type differential pressure transducer, together with the MPC 101 converter. At first the flow of water flux was measured and a great compatibility of results of all flow meters was achieved. The maximum relative deviation did not exceed 2%. Next a 0.5% water solution of methylcellulose with an addition of 0.5 % powdered chalk - with regard to the mass of the solution. The liquid was a suspension of powdered chalk in the water solution of methylcellulose.
