<p>The flowmeter has two chambers connected respectively to an in put and a fluid output whose flow is to be measured. The chambers are separated by a flexible membrane whose displacement actuates a read system. The membrane (3) has in its centre a finger (8) which has an axial channel (a) and a lateral hole (10) which communicate between the two chambers (4, 5). The finger (8) comes up against a flexible reset element (12). The reset element (12) is actuated by the effect of deformation of the membrane (3). An element (11 or 21) actuates the read system (17).</p> |
