Method and device for monitoring the evolution of the current value of a flow of fluid in a fluid meter.

摘要

The invention relates to a method for monitoring the evolution of the current value of a flow of fluid in a fluid meter, which comprises a measuring unit and an axis of rotation (1) connected to said measurement unit, and able to enter into rotation around it, even when a volume of fluid passes through the measuring unit, characterized in that it consists in detecting the rotational movements and rotation of the axle according to a sampling frequency is variable according to a predetermined sampling relationship, said frequency is defined as a function of at least a predetermined value of flow of fluid, and to be processed electronically of the information corresponding to a detection and to a failing to detect a movement of rotation of the axis of said sampling frequency in order to determine, on a continuum of flow rates, the current value of the fluid flow with respect to the predetermined value of flow of fluid contained in said continuum of flow rates.
