Abstract
A photoelectric sensor is composed of an infrared emitter and an infrared receiving device. The infrared emitter is composed of infrared emission tubes that are arranged on a flow tester and correspond to measuring scales one by one. The infrared receiving device is composed of infrared receiving tubes that are arranged on a flow tester and correspond to the infrared emission tubes one by one. When a to-be-detected medium is put into the flow tester and the liquid level does not reach the position of the infrared emitter, an infrared ray is normally received by the infrared receiving device and a low level is output by the photoelectric sensor. When the liquid level reaches the position of the infrared emitter, the infrared ray is refracted on the liquid level and can not be received by the corresponding infrared receiving device, and a high level is output by the photoelectric sensor. The photoelectric sensor of the utility model is floatless, thereby substantially minimizing restriction of detection conditions by a float. Moreover, a flowmeter manufactured by the photoelectric sensor can be used for both detection of instantaneous flow and accumulated flow, and is wide in measuring range from 2ML\h to 20L\h with an error less than 1%.

Low levelWhen liquid level reached the position of infrared launcher, IR reflected at the liquid level place, and corresponding with it infrared receiving device does not receive IR, photoelectric sensor output
High level
Described flow tester is the flow tester of transparency liquid, and above-mentioned transparency liquid is meant any one in water, diesel oil or the alcohol.
A kind of photo-electric floatless flowmeter that adopts the sensor to process; It comprises vertically disposed at least one U type test tube; The top of U type test tube is provided with medium and flows into valve, and the bottom of U type test tube is provided with medium and flows out valve, it is characterized in that: on the arm in said U type test tube photoelectric sensor is set; The infrared launcher of photoelectric sensor is positioned at a side of arm, and the infrared receiving device of photoelectric sensor is positioned at the opposite side of arm; The signal output part of said photoelectric sensor connects microcontroller, and the output terminal of microcontroller connects display device and warning device.
It comprises at least two U type test tubes, and it is tee ball valve that the medium that U type test tube top is provided with flows into valve, and it is solenoid valve that the medium that U type test tube bottom is provided with flows out valve.
Also be provided with medium overflow outlet at the top of U type test tube.
Adopt the utility model of technique scheme, photoelectric sensor is the floatless formula, has significantly reduced the restriction of float to condition determination like this.And by the flowmeter that this photoelectric sensor is processed, can measure instantaneous delivery and can measure integrated flux again, and range ability is wide: 2ML/h-20L/h, error is less than 1%.
Description of drawings
Fig. 1 is the structural representation of photoelectric sensor in the utility model.
Fig. 2 is the structural representation of photo-electric floatless micrometeor flowmeter in the utility model.
Embodiment
As shown in Figure 1, the photoelectric sensor in the utility model is made up of infrared launcher and infrared receiving device.Above-mentioned infrared launcher is by being arranged on the flow tester 1, forming with the infrared transmitting tube 2 of measuring the corresponding one by one setting of scale; And infrared receiving device is by being arranged on the flow tester 1, forming with the infrared receiving tube 3 of the corresponding one by one setting of infrared transmitting tube 2.
The principle of work of above-mentioned photoelectric sensor is: when measured medium entering flow tester, when liquid level did not reach the position of infrared launcher, infrared receiving device normally received IR, the photoelectric sensor output low level; When liquid level reached the position of infrared launcher, IR reflected at the liquid level place, and corresponding with it infrared receiving device does not receive IR, photoelectric sensor output high level.Note the liquid level corresponding scale required time that goes up, just can calculate the flow under the current measurement unit.
Need to prove that above-mentioned flow tester is the flow tester of water, diesel oil or alcohol, promptly the utility model only is applicable to the measurement of transparency liquid; In addition, this flow tester can also can be the electronic type flow tester for simple U type test tube.
A kind of photo-electric floatless flowmeter that utilizes the sensor to process, it comprises vertically disposed at least one U type test tube 4, the quantity of this U type test tube can be decided according to the actual requirements, and can be merely one, also can be set up in parallel for two, three.The top of U type test tube is provided with medium and flows into valve 5, and the bottom of U type test tube is provided with medium and flows out valve 6.On the arm of the utility model in U type test tube photoelectric sensor 7 is set, the infrared launcher of photoelectric sensor 7 is positioned at a side of arm, and the infrared receiving device of photoelectric sensor is positioned at the opposite side of arm, their corresponding settings.And the signal output part signal of communication line 8 of photoelectric sensor connects microcontroller, and the output terminal of microcontroller connects display device and warning device, and above-mentioned display device and warning device are the technology that ordinary skill is known.
Need to prove that the preferred forms of the utility model is: it is tee ball valve that the medium that U type test tube top is provided with flows into valve, and it is solenoid valve that the medium that U type test tube bottom is provided with flows out valve, and tee ball valve all is connected with microcontroller with solenoid valve.
Also be provided with medium overflow outlet 9 at the top of U type test tube.
The principle of work of flowmeter in the utility model: glass U type test tube needs vertical fixing, and when measured medium got into glass U type test tube one or two through tee ball valve, the solenoid valve of test tube bottom was in closed condition.Because medium overflow outlet is identical with atmospheric gas pressure, the both sides liquid level of U type test tube equates, measures liquid level flow on one side, through calculating, just draws whole U type test tube flow.Liquid level does not have float, and the photoelectric induction device of the both sides through being fixed on one of them arm of U type test tube comes the tracer liquid flow, utilizes photoelectric induction device to improve the accuracy of leaning on human eye to measure, and advance is improved to scientific measurement to perceptual understanding.When the medium full scale perhaps tests, open solenoid valve, medium flows out.
This apparatus structure is simple, and is easy for installation, do not have specific installation environment and requirement, and measuring accuracy is high, and cost is lower than other electromagnetic type or suspended body flowmeter.
