Flow is to be measured and input to a computer. For maximum resolution, we want the minimum flow, , to correspond to 00H, and the maximum, , to correspond to FFH from an 8-bit converter.
The flow is measured as a voltage given by V = 0.0022 Q2, where Q is the flow in . Develop the signal conditioning and ADC reference that will provide this specification.
What is the resolution of flow when the flow is at the lower limit and at the upper limit? Explain why there is a difference.
