Turbine flow monitoring device |
摘要 |
A turbine type flow meter has a four-vaned plastic torpedo-shaped turbine mounted by portions of the plastic turbine within a housing between first and second bearings. The turbine supports a pair of magnets of the Neodymium-Iron-Boron type which rotate with the turbine. An upstream portion of the housing incorporates a sensor cavity, which is sealed from a flow cavity containing the turbine. A connector and an attached printed circuit board with a Hall effect sensor is mounted within the sensor cavity closely spaced from the rotating magnets. The sensor housing is constructed from two parts. Each part of the housing incorporates mating structures that are designed for joining by spin welding.
