Embodiment

A kind of autoluminescence flowmeter that the utility model provides, it is at flowmeter glass tube rear design ray structure, can make the number of degrees of glass tube of flowmeter high-visible.

Referring to Fig. 2, Fig. 2 is the exploded perspective view of the autoluminescence flowmeter embodiment one that provides of the utility model.

As shown in Figure 2, the autoluminescence flowmeter that present embodiment one provides comprises: flowmeter bodies 1, and its flowmeter bodies 1 integral body is a groove 10, is used for showing that the glass tube 11 of the flow number of degrees is built in described groove 10;

Described flowmeter bodies 1 side is provided with one and makes the visible ray structure 2 of described glass tube 11 clear scales.

In specific implementation, described ray structure 2 is P.e.c. assembling PCBA plate 2, as shown in Figure 3, is provided with row's light emitting LED lamp 20 on the described PCBA plate 2.

Concrete, also be provided with one on the described PCBA plate 2 for the interface 21 of regulating described LED lamp 20 brightness.

By this interface 21, can regulate the brightness of LED lamp 20, to satisfy in the different light rays situation, make the visible demand of clear scales of glass tube 11.

Need to prove that the LED lamp can with white light as light source, also can adopt other colors, other forms of light source according to demand.

Implement the autoluminescence flowmeter that the utility model provides and since be provided with in the flowmeter bodies side can brightness adjusting self-illuminating structure, can make the number of degrees of flowmeter glass tube more clear, the convenient operation person is to the accurate extraction of flowmeter information.
