Abstract
The present invention relates to a pneumatic flow measuring system for measuring fluid flow. More particularly, the disclosed preferred embodiment of the present invention is referred to as a square root extractor as the device basically functions to compute the square root of a pneumatic input signal by producing an output signal that is linear with flow or fluid velocity of a system being measured. Thus, although flow between two points may be basically defined as a square root function of a differential pressure between the same two points, the flow measuring device of the present invention utilizes a differential pressure input signal to produce an output signal that is linear with flow.
