Abstract
The electronic nutating disc flow meter is suitable for measuring different liquids with varying viscosities. This meter is best suited for measuring medium viscosity fluids of 10 to 450 centipoise. This flow meter includes a microprocessor to correct for the nonlinearity of fluid flow. The memory in the microprocessor contains three calibration curves with accompanying lookup table information. CAL A is preset at the factory for thin viscosity fluids. CAL B is preset at the factory for medium viscosity fluids and CAL C can be field calibrated. The calibration curves can be plotted with up to five points per curve.
