Abstract:
In the ‘Metrology for improved power plant efficiency’ project the Reynolds dependence of four flow meters used for feed water flow measurements were investigated. The four flow meters were ultrasonic, inductive, orifice plate and Venturi tube flow meter. The measurements were performed up to 90 °C to study the temperature dependence of the meters. An extrapolation model up to 230 °C was developed to measure the feed water flow with an uncertainty in the range of 0.3 % – 0.5 %. The influence of a double bend out of plane disturbance on the meters was also investigated. Some meters showed a significant dependence.
