In this paper continuous measuring of water viscosity by Coriolis flow meter is analyzed. The idea of technical solution for determining fluid viscosity by Coriolis flow meter and Hagen-Poiseuille equation was elaborated. Pressure drop was measured at the Coriolis tube instead of at the straight pipeline section. The aim of the research is to consider the possibility of applying the proposed technical solution for reliable determination of water viscosity. It was proved that by taking into account the temperature of water t and hydraulic parameters of measurement system Δp/Q, the proposed technical solution can be a reliable method for continuous monitoring of water viscosity, even if Hagen-Poiseuille flow was not achieved. The proposed solution decreases the number of necessary sensors for viscosity measuring, and makes the system and facility more compact. Compared to the conventional parallel mounted capillary viscometer with constant flow pump, the proposed technical solution is much cheaper. The presented technical solution of the measurement system requires a long process of calibration in real terms.
