Automatic power generation type flowmeter. |
摘要 |
<p>An automatic power generation type flowmeter generates a measuring signal through measuring of a flow rate of fluid flowing through a passage and transmits it to a receiver at a remote location. The flowmeter includes a power generator coupled to a detection shaft rotated under an action of a fluid flowing through the passage and outputting an electric signal. The power generator (46) includes a permanent magnet (72) having S- and N-poles, an electromagnetic coil having a core around its axis and arranged adjacent to the magnet (72) with the axis of the coil located in a direction substantially perpendicular to a rotation shaft (75), a first stator (81) magnetically coupled to the core and having its magnetic induction portion arranged opposite to the N-pole of the magnet (72), and a second stator (82) magnetically connected to the core and having its magnetic induction portion arranged opposite to the S-pole of the magnet (72). <IMAGE></p> |
