Method and device for measuring the flow rate of a fluid

摘要

The liq. passing through a measuring and transmitting unit (1) rotates a propeller (3) about an axis (4) parallel to the direction of flow (F). A magnet (31) on one of the propeller blades produces a signal in a coil (51) of a sensor (5) at each revolution. The characteristics of the particular measuring and transmitting unit (1) are stored in a memory (9). The memory (9) and sensor (5) are connected to a remote electronic unit (7). This unit has a dialogue module (11) which imports the transmitter characteristics from the memory (9) for use in the remote electronic unit (7).
