Fig. 2 is the connection layout of acquisition control system and seized flowmeter, standard measuring equipment.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

The said high-effect flow automatic calibration system of the utility model has been done technological incorporation with method of standard table detection system, volumetric method detection system and mass method verification system.Fluid through standard scale, flows to seized flowmeter earlier, flows to the volumetric standard device or the standard set-up of weighing again.According to the difference of the bore or the instantaneous delivery of seized flowmeter, select wherein some standard scale detection branch that seized flowmeter is demarcated, the utility model is easy to operate, and the scope of application is big.

Embodiment 1

When seized flow is counted the mechanical flow timing, delivery rate pulse signal not directly, the signal-arm that needs to gather seized flowmeter through laser detector comes the calculating cumulative flow.

As shown in Figure 1; The high-effect flow automatic calibration system of the utility model; Can detect m seized flowmeter simultaneously, it comprises standard scale pick-up unit, acquisition controller, host computer, a m laser detector, volumetric standard device, weigh standard set-up and two photoelectric sensors.Wherein, the standard scale pick-up unit comprises the standard scale detection branch of n parallel connection, and each standard scale detection branch is connected to form through pipeline by controlled valve, standard scale and control valve successively.

M seized flowmeter connected successively; Form seized flowmeter string; All fixing laser detector on each seized flowmeter; One end of seized flowmeter string links to each other with the standard scale pick-up unit, and the other end links to each other with the standard set-up of weighing with the volumetric standard device respectively, respectively connects a photoelectric sensor on the commutator of the commutator of volumetric standard device and the standard set-up of weighing.The controlled valve of standard scale pick-up unit, standard scale and control valve, seized flowmeter, laser detector, photoelectric sensor all link to each other with acquisition controller.Acquisition controller, volumetric standard device and the standard set-up of weighing all link to each other with host computer.N and m are natural number.

Standard scale pick-up unit, volumetric standard device and the standard set-up of weighing can realize that method of standard table, mass method and the volumetric method of flow detection are three-in-one.

The course of work of the utility model is following:

1, after said acquisition controller receives the detection sign on that host computer sends, according to the integrated flux and the timing of the seized flowmeter of photoelectric pulse signal integrating of the laser detector that receives;

2, acquisition controller sends enabling signal to standard scale pick-up unit, volumetric standard device and the standard set-up of weighing simultaneously, also picks up counting receive the standard integrated flux start signal of standard scale pick-up unit, volumetric standard device and the standard set-up of weighing when acquisition controller after;

3, after the integrated flux of seized flowmeter had reached the integrated flux of presetting, acquisition controller finished timing, records detection time, sends stop signal to standard scale pick-up unit, volumetric standard device and the standard set-up of weighing simultaneously;

4, the acquisition controller integrating goes out the standard integrated flux of standard scale pick-up unit, volumetric standard device and the standard set-up of weighing, and records detection time;

5, calculate the error of seized flowmeter by host computer.

Acquisition controller can be realized by PLC as the transmission and the receiving terminal of calibrating start stop signal, can realize simultaneously that the series connection of a plurality of seized flowmeters is measured.Acquisition controller receives the enabling signal that host computer sends, thus the start and stop of control detection.Behind completing steps 4, the timing that detects is sent to host computer with integrated flux integrating result carry out measuring error calculating.
