Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, wheeled tiny flow quantity flowmeter of the present utility model, comprises impeller 1, upper cover 2, box body 3, wiring board 4 and wiring board lid 5; Described upper cover 2 and box body 3 are interconnected, and described wiring board 4, between wiring board lid 5 and upper cover 2, described wiring board 4 is also provided with Hall element 6; In the cavity of described impeller 1 between upper cover 2 and box body 3, this flowmeter is also provided with stainless steel shaft 7, and described impeller 1 is coupling by stainless steel shaft 7 and box body 3; The blade upper end of described impeller 1 is provided with magnet 8, and wherein, when impeller 1 rotates, Hall element 6 and magnet 8 are on same perpendicular line.
Described magnet 8 and impeller 1 adopt plastic package, and namely magnet 8 and impeller 1 are by plastic wraps, prevent magnet 8 from soaking in water and cause demagnetization, improve serviceable life.
Be provided with O type circle 9 between described upper cover 2 and box body 3, increase sealing, improve its burst pressure (common tiny flow quantity flowmeter can only accomplish 10-15bar, and flowmeter of the present utility model can accomplish 35bar).
Described wiring board 4 one end is provided with extension line 10.
Described extension line 10 end is provided with terminal 11.
Utility model works principle: the principle of work of type flowmeter is that impeller is placed in detected fluid, rotates by the impact of fluid flowing, reflects the size of flow with the speed of vane rotary.The accuracy of the turbo flow meter that electric impulse signal exports is higher, (measuring technique of Hall element is comparatively ripe to adopt Hall element to carry out displacement detecting, belong to common practise), make the converter of flowmeter without any need for movable mechanical component, what eliminate mechanical component asks friction force and driving error, achieve all electronic and the miniaturization of flowmeter converter, flowmeter has the features such as accuracy is high, reliability is high, structure is simple, intelligent.
In sum, above-mentioned embodiment is not restricted embodiment of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
