Specific embodiment
Below in conjunction with the accompanying drawings the utility model is further illustrated.
As shown in figure 1, the utility model includes metering system 1 and control system 2, the metering system 1 is included by pipe
Liquid barrel 11, pump 12, flowmeter 13 and liquid valve 14 that line is sequentially connected, each part of the control system 2 and metering system 1
Be connected, control system 2 is analyzed calculating by particular data model to the signal that flowmeter 13 feed back, controlling pump 12 with go out liquid
The opening and closing of valve 14, so as to realize the precise control of fluid flow.Fluid flow is calculated using flowmeter 13, relative with
Weighting manner structure is simpler, it is not easy to error occur, flowmeter 13 is placed between pump 12 and liquid valve 14, is reduced
When flowmeter 13 starts, 13 liquid feeding end of flowmeter and the pressure differential of outlet end, can greatly improve reliability and the precision of measurement.
The control system 2 includes singlechip controller 21 and power supply 22, the control end of singlechip controller 21 and pump 12,
13 signal end of flowmeter, 14 control end of liquid valve are connected.Controlled using single-chip microcomputer, program is simple, and reliable and stable.
Further, data background terminal 3 is additionally provided with outside the control system 2, data background terminal 3 is responsible for single-chip microcomputer control
The Data Collection of device processed 21 and process, then signal is fed back to singlechip controller 21 is carried out to each part of metering system 1
Control.Data background terminal 3 is provided simultaneously with online payment function and big data processing function, ensure that singlechip controller 21
Safely and steadily run.
The process of selling of the present utility model is：After singlechip controller 21 receives and sells signal and sell capacity,
Start pump 12 and liquid valve 14 successively, liquid is carried out out, flow signal is fed back to singlechip controller 21, single-chip microcomputer by flowmeter 13
