Description

The low-power consumption of flowmeter formula compensates computer fuel charger automatically

The utility model relates to the low-power consumption of a kind of flowmeter formula and compensates computer fuel charger automatically.

The computer fuel charger of existing oil station usefulness, meter is a tetra-piston type, and the restriction of certain flow is arranged, and is 60 liters/minute at present, the flow error variation can't realize automatic compensation in addition, cause the accuracy of measuring low, and the fuel charger power consumption is also high.

The purpose of this utility model provides a kind ofly measures and the flowmeter formula low-power consumption of pin-point accuracy of compensation automatically compensates computer fuel charger automatically with flow instrument.

The purpose of this utility model is achieved in that the low-power consumption of flowmeter formula compensates computer fuel charger automatically, include inlet union (1), filtrator (2), oil gun (5), housing (8), oil window (9), display system (6) and zero resetting device (7), its special character is that it also includes dry cell (4) and transmitter (3), transmitter is the flowmeter formula, dry cell (4) links to each other with display system (6), display system (6) is a microcomputer display system, display system (6) links to each other by sensor with transmitter (3), 51 series monolithic 80C31 are as core component, and the PO mouth meets EPROM and E through latch 8282 ²PROM is the low order address end of 27C64 and 28C16, the PI mouth directly connects the high address end of 27C64 and 28C16, the data selecting side of PO mouth

wiring code translator

4515,4515 output termination drives, the input end of code translator MC14547, the input end that the output terminal of while 4515 is also given the radix point translation circuit is CD4001 and CD4069, remove to give liquid crystal display device TO-21C and TO-30B shows integrated flux and instantaneous delivery respectively by the output terminal of MC14547, oscillator adopts the external crystal in internal oscillator source and two electric capacity of 80C31, and the sensor signal input end is through the INTI end input of the anti-phase back of one-level phase inverter by 80C31.

Compare with existing computer fuel charger, the utility model uses flowmeter as transmitter, and the nonlinear transformation of flow realized compensation automatically, thereby reach accuracy of measuring height, the utility model is owing to adopt low-power consumption element and interruptedly supplying power in addition, so can adopt dry cell as power supply, again owing to adopt dry cell power supply, avoided interference from electrical network, its antijamming capability is very strong, and the utility model also has the advantage that cumulative data is not lost when changing battery or dead battery, and cell voltage is low and during dead battery, light emitting diode flashes warning, and battery is changed in prompting.

Be described in detail technical solution of the present utility model below in conjunction with accompanying drawing.
