ABSTRACT:
A fluid flow measuring system composed of: a venturi connected to conduct the fluid whose flow is to be measured and having two outlet ports between which a pressure differential proportional to such fluid flow is created; a movably mounted measuring element having a selected zero position and connected to the venturi to be subjected to a displacement force corresponding to the pressure differential; a transducer unit associated with the measuring element for producing an electrical signal representative of the displacement of the measuring element from its zero position; a regulating device having a signal input connected to receive the electrical signal, and a signal output, and presenting a transfer characteristic having an integrating component such that the signal at the signal output is representative of the magnitude and duration of displacement of the measuring element from its zero position; a signal squaring circuit connected to the regulating device for generating a control signal dependent on the square of the signal at the output of said regulating device; and a hysteresis-free electromagnetic system connected to apply to the measuring element, in response to the control signal, a magnetic displacement force of a magnitude and direction to cause the measuring element to reach its zero position.
