Fig. 1 is the principle of work schematic diagram of the utility model flow measurement device.
By reference to the accompanying drawings, in the utility model embodiment, Reference numeral is as follows:
1-tubular body (sectional area S is definite value, i.e. sectional uniform tubular body); 2-confluxes threeway; 3-drain solenoid valve; 4-first liquid level light electrical sensor apparatus; 5-second liquid level light electrical sensor apparatus; 6-digital display control axis system.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
According to the utility model embodiment, as shown in Figure 1, provide a kind of flow measurement device, particularly a kind of Full-automatic portable flow measurement device based on photoelectric sense technology.
The technical solution of the utility model, utilize photoelectric sense technology, according to measured current, liquid level is full of time t used by the tubular body (as tubular body 1) of L length the first liquid level light electrical sensor apparatus (as the first liquid level light electrical sensor apparatus 4) position to the second liquid level light electrical sensor apparatus (as the second liquid level light electrical sensor apparatus 5) position, calculates the flow q of measured current.Known: it is definite value that S is amassed in tubular body geometric cross section; The spacing L definite value of two sensors; So L length tubular body volume v is also definite value between its photoelectric sensing apparatus 1 position to photoelectric sensing apparatus 2 position, v=S*L*2; Time t is that the photosignal that the photosignal that transmits when arriving the first liquid level light electrical sensor apparatus position according to liquid level of control axis system and liquid level are transmitted when reaching the second liquid level light electrical sensor apparatus position draws automatically:
Q=v/t; Q-flow, unit: l/h; V-volume between the tubular body L of both sides, unit: rise; T-be full of the volume time used between tubular body L, unit: hour.
the workflow of technical solutions of the utility model is as follows:
Tested douche is fixed on the top of technical solutions of the utility model, the uniform fluid flow instillation tubular body entrance after water flowing pressurization, douche being flowed out, starts douche detection system:
Digital display control axis system (as digital display control axis system 6) send drain command--drain solenoid valve (as drain solenoid valve 3) open--threeway of confluxing (as threeway 2 of confluxing) interior water emptying--drain solenoid valve closedown--tubular body in liquid level--the first liquid level light electrical sensor apparatus that starts to rise detect that liquid level generates photosignal transmitting--digital display control axis system and accepts Photoelectric Signal Processing--the second liquid level light electrical sensor apparatus detect that liquid level generates photosignal and transmits the display of--digital display control axis system accepts photosignal calculation process--measurement result.
Each known parameters can be arranged from control axis system man-machine interface above, accurately revises this directional error.Above result of calculation display also regularly stores, and measured data on flows can be exported from USB interface simultaneously.
