Abstract
The utility model relates to an electric rotary piston flowmeter for measuring the liquid in a pipeline comprising a meter head, a meter bottom and a magnetic element restricted on the meter bottom and moving along a fixed track, also comprises a circuit plate in the meter head and two and more sensors arranged above the magnetic element along the magnetic element motion track, wherein the sensor is electrically connected to a central processing unit of the circuit. The electric rotary piston flowmeter guarantees the precision coherence and provides authoritative data for the centralized treatment and dynamic analysis of data and precise management of fuel because the far-transfer of the electric line is conveniently realized.
Description
Technical field:
The utility model relates to a kind of liquid flow mearuement device, refers in particular to a kind of electronic type rotary-piston flowmeter that can measure the liquid in the pipeline.
Background technology:
At present, overwhelming majority rotary-piston type liquid flowmeter all is based on full mechanical: the piston of flow of liquid at the bottom of enclosed watch rotates, driving one or two magnetic patch rotates, then the gauge outfit magnetic patch of outside, magnetic field, the gauge outfit magnetic patch and then rotates the mechanical digital wheel disc device that drives on the gauge outfit together and rotates, and is indicated the oil mass of passing through by mechanical wheel disc.Minority is follow-on to be on the impeller of original mechanical type numeral wheel disc magnetic patch to be installed, and magnetic patch rotates during wheel rotation, the electronics copy device far away that the Wei root sensor on induction next door or drive tongue tube are formed.There is following shortcoming in said structure: the mechanical data wheel disc exist data can not teletransmission, do not have flow speed data, make troubles for the centralized management of monitoring; Drawbacks such as there is problems such as can not discerning reversing in the electric transducer that installs additional, causes the consistance of unified management difficulty, precision of data poor, and the initiating flow is big.
Summary of the invention:
In order to overcome many deficiencies of original flowmeter, the invention provides a kind of solve just to reverse detect and the electronic type rotary-piston flowmeter of other drawback problem.
For achieving the above object, the technical scheme that the utility model provides is: electronic type rotary-piston flowmeter, include gauge outfit, the table end and be limited to table and the magnetic element that moves along fixation locus at the end, also include and be loaded on the circuit board in the gauge outfit and be positioned at two or more sensors that the magnetic element top is provided with along the magnetic element movement locus, wherein the central processing unit of sensor and circuit board electrically connects.
Described two or more sensors along the setting of magnetic element movement locus become angle.
Described magnetic element is a magnet.
The utility model utilizes the rotating magnetic field of sensor sensing to the magnetic element of table at the end, passing to the central processing unit of circuit board handles, the sequence that central processing unit forms according to the asynchronism(-nization) that arrives with two or more sensor signals, discerning just changes and reverses, thus to data add up, tired subtracting.Because full-digital circuit, there is not mechanical friction, avoided the influence of precision at the bottom of the original gauge outfit friction his-and-hers watches, the consistance of his-and-hers watches has better assurance.
Beneficial effect of the present utility model is: guaranteed the consistance of precision, and electronic circuit easily realizes teletransmission, for the accurate management of the focusing on of data, performance analysis and fuel oil provides authoritative field data.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.See Fig. 1-shown in Figure 2, include gauge outfit 1, the table end 2 and be limited to table and the magnetic element 3 that moves along fixation locus at the end, the main improvement of present embodiment is, also include and be loaded on the circuit board 4 in the gauge outfit and be positioned at two sensor 5 and the sensors 6 that are mutually angle of magnetic element 3 (being generally magnet) top along the setting of magnetic element movement locus, wherein sensor 5 and sensor 6 electrically connect with the central processing unit of circuit board 4 respectively.
In conjunction with the accompanying drawings shown in 3, when forward passes through oil, magnetic element 3 clockwise rotates along fixation locus, when sensor 5 and sensor 6 were far away, two sensors all were low levels, and promptly waveform S1 and waveform S2 are low levels, see time period T1, when magnetic element 3 forwarded near sensor 5 clockwise, waveform S1 became high level, and sensor 6 is far away from magnetic element 3, waveform S2 remains low level, see time period T2, magnetic element 3 continues to clockwise rotate, during near sensor 5 and sensor 6, waveform S1 and waveform S2 become high level, see time period T3, magnetic element 3 then clockwise rotates, away from sensor 5, waveform S1 has become low level, at this moment sensor 6 is still near from magnetic element 3, and waveform S2 remains high level, sees time period T4, magnetic element 3 clockwise rotates again, away from sensor 5 and sensor 6, waveform S1 and waveform S2 become low level again, see time period T5.If oil is always in forward flow, magnetic element 3 is clockwise rotating always, will follow the time series of repetition time section T1, time period T2, time period T3, time period T4, time period T5, and is every through a sequence, and a pulse just adds up.
Oppositely by oil the time, magnetic element 3 rotates counterclockwise along fixation locus, when sensor 5 and sensor 6 are far away, two sensors all are low levels, be that waveform S1 and waveform S2 are low levels, see time period T5, when magnetic element 3 forwards near sensor 6 counterclockwise, waveform S2 becomes high level, sensor 5 is far away from magnetic element 3, and waveform S1 remains low level, sees time period T4, magnetic element 3 continues to rotate counterclockwise, during near sensor 5 and sensor 6, waveform S1 and waveform S2 become high level, see time period T3, magnetic element 3 then rotates counterclockwise, away from sensor 6, waveform S2 has become low level, and at this moment sensor 5 is still near from magnetic element 3, waveform S1 remains high level, see time period T2, magnetic element 3 rotates counterclockwise again, away from sensor 5 and sensor 6, waveform S1 and waveform S2 become low level again, see time period T1.If oil is always in reversed flow, magnetic element 3 is rotating counterclockwise always, will follow the time series of repetition time section T5, time period T4, time period T3, time period T2, time period T1, and is every through a sequence, just tires out to subtract a pulse.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
