The gas and liquid medium flow meter is characterized in that the gas and liquid medium flow meter is used for measuring the gas and liquid flow, the gas and liquid medium flow meter is used for detecting the flow device in the meter, the flow device is used for driving the transmission device, the transmission device is used for driving the decimal pointer, the decimal pointer is used for driving the integer character wheel to rotate, and the numerical value of the meter can be read with high precision by reading the decimal pointer. The usual method is to mount one or two permanent magnets on the pointer and hall or magneto-resistive sensors on the permanent magnets or on the sides, which are simple but easily affected by external magnetic fields. The other is that the pointer is made into a disc with a part covered with a metal sheet, and the rotation of the disc is detected through a coil or an inductor, so that the external magnetic field resistance is high, the external strong magnetic field interference is still generated, and meanwhile, under the condition that wireless transmission modes such as NB-IoT and the like are increasingly used, the mode is easily influenced by an electromagnetic field generated by signal transmission during data uploading. Another common photoelectric direct reading scheme is to collect integer character wheels, and the precision can not meet the requirements of some users.
Therefore, the application designs a photoelectric type non-magnetic rotary counter to solve the problems.
Disclosure of Invention
In order to make up for the defects in the prior art, the utility model provides the photoelectric type non-magnetic rotary counter which is not influenced by an external electromagnetic field, and meanwhile, the photoelectric type non-magnetic rotary counter for detecting the relative value of light instead of the absolute value has stronger capability of resisting the influence of external environment light.
The utility model is realized by the following technical scheme:
an optoelectronic non-magnetic rotary counter, includes the disc pointer, its characterized in that: the disc pointer is of a rotatable disc structure, the upper surface of the disc is divided into three sector areas with different colors, a transmitting tube and a receiving tube are arranged above the disc pointer, and a light barrier is arranged between the transmitting tube and the receiving tube.
Further, in order to better realize the utility model, the three sector areas with different colors are respectively a red area, a green area and a blue area, and the three areas equally divide the disc to occupy 120 degrees respectively.
Further, in order to better implement the present utility model, the emitting tube is composed of one full spectrum white light emitting diode or three near red, green and blue light emitting diodes.
