Abstract
The invention discloses a bidirectional variable magnetic resistance type turbine flow switching and delivering device. A turbine flowmeter is a delivery-measurement type flowmeter and is composed of a turbine flow sensor and a flow display instrument. When the flowmeter works, measured fluid impacts turbine blades, a turbine is made to rotate, delivery of the turbine varies with the flow, in another word, the flow is great, a flow device which is currently used cannot maintain the calibration characteristics for a long time, and fluid physical properties have great influence on the flow characteristics. Suspended matter or corrosive elements contained in a medium can cause the problems of bearing wear and clamping and the like. The bidirectional variable magnetic resistance type turbine flow switching and delivering device comprises a switching and delivering device shell (2), the switching and delivering device shell is connected with a fastener (1) and a surface body outer wall (10), and magneto-electricity induction type signal detectors (6) are installed inside the surface body outer wall. The device is mainly applied to power station closed pipeline flow measurement.
