Abstract:
1. A meter, comprising: a flow path for fluid to be measured; means for applying a signal across a normal part of said fluid path and detecting said signal so as to provide an indication of whether or not fluid is present in said normal fluid path; a flow measuring fluidic oscillator that produces a flow measurement signal that varies non-linearly with flow rate of said fluid; storage means containing data specific to said fluidic oscillator that represents a relationship between said flow measurement signal generated by said fluidic oscillator and the flow rate measured by said fluidic oscillator; and processing means for processing said flow measurement signal from said fluidic oscillator and said fluidic oscillator specific data to produce an output signal representative of flow but independent of fluidic oscillator characteristics represented in said fluidic oscillator specific data, such that the output signal varies substantially linearly with flow rate.
