I am trying to build a device to adjust the output of an air flow sensor. The sensor is calibrated for operation in a 2.75" OD tube and I need it to function correctly in a 3" OD tube. So the signal would be off by approximately 19% I believe. Voltage output varies linearly by 0-5 volts depending on air flow.
Can I just use a basic op-amp circuit or would that not be accurate enough? It needs to be adjustable so I can fine tune it and my experiance with varriable resisters is that they are not very accurate.
Any help would be appreciated.

Paul
