Abstract (en)
[origin: WO2022106961A1] The present invention describes a flowmeter, the body of which has a low-flow-rate module (20) and a high-flow-rate module (30). The low-flow-rate module and the high-flow-rate module are fluidically connected via an intermediate chamber (24). The low-flow-rate module has a mobile piston, the position of which depends on the flow rate to be measured when it is below a certain threshold value. The high-flow-rate module has a vaned wheel designed to measure higher flow rates.
