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.

A calibration apparatus includes a microcomputer-based calibrator unit, functioning separately from a measuring device to be calibrated, and a coupling coil, through which calibration information generated by the calibrator unit is electromagnetically transmitted to the measuring device to which the coil is strapped or otherwise connected. This permits the measuring device to be calibrated without the measuring device being removed from the environment in which it is to make measurements. The methodology of the apparatus permits the measuring device to be calibrated either with standard calibration data, such as whereby the measuring device is calibrated to a factory standard calibration, or with variable calibration data, such as whereby a then-current calibration of the measuring device is 'tweaked'.

An optical card is oscillated in an X direction along a curved path by a voice coil driver, and an optical read/write module is translated in the Y direction to read recorded information on the card.
