The ECU has to do the compensation. The potentiometer is laid out
ratiometrically so that the the ECU doesn't have to worry about
compensating for any temp. drift in that element.

The sensor in the Bosch flowmeters is typically NTC. You should be
able to fit typical curves/constants in the donor Volvo's service
manual.
