  • Flow rate computer
    Patent number: 3965341
    Abstract: A method of correcting the non-linearity of flow meters to extend their usable range, including alternate means to manually enter fluid viscosity by front panel switches or by an analog to digital converter from a temperature probe. The flow rate computer computes frR, divides it by fr/Mfi to yield an output signal fo = MRfi which is a more accurate and linear signal versus flow representation. The flow rate computer extends flowmeter linear range by as much as 100 to 1.
