Claims: What is claimed is:

1. A Flow Rate Computer for correcting the non-linearity of flow meters comprising:

converter means for converting an analog representation of viscosity to a digital representation;

digital shaper means for digitizing the manual assignment of viscosity and analog representation thereof;

a reference oscillator;

a first rate multiplier having an input and an output, the input being connected to the digital shaper and reference oscillator whereby the first rate multiplier provides a signal proportional to the reference oscillator frequency and the viscosity;

first accumulator means for receiving the output of the first rate multiplier;

a second rate multiplier;

a read-only memory programmed according to flow meter data to provide a signal R to second rate multiplier having an input and an output, the input being connected to the read-only memory and the reference oscillator whereby the second rate multiplier provides a signal proportional to the reference oscillator frequency and R;

a first divider with an input connected to the reference oscillator whereby the first divider provides for division of the reference oscillator frequency by a pre-set integer determined by the flow meter characteristics;

a second accumulator means for receiving the output of the first divider;

a latch means for updating the number stored in the second accumulator;

second divider means for dividing output of first rate multiplier by the number held in the latch;

a third rate multiplier having an input and an output, the input being connected to the digital shaper and second divider means; and

a panel rate display actuated by output of second divider or density rate multiplier.
