Embodiment
Below in conjunction with accompanying drawing, and other technical characteristic above-mentioned to the utility model and advantage are carried out clearly and completely
Description, it is clear that described embodiment is only section Example of the present utility model, rather than whole embodiments.
Reference picture 1, present embodiments provide a kind of electromagnetic swirl flowmeater, it include swirl generating body 1 in housing 4,
Magnetic pole 2 and detecting electrode 3, the magnetic pole 2 and the detecting electrode 3 are respectively positioned on the side of the swirl generating body 1；Wherein,
Existing structure is remained in swirl generating body 1, magnetic pole 2 and detecting electrode 3 etc., here is omitted.
As an improvement, a kind of electromagnetic swirl flowmeater that the present embodiment provides also includes the advanced unit 5 of phase and phase steric retardation
Unit 6 afterwards, the output end of the advanced connecting detection electrode 3 of unit 5 of phase, the output of the also connecting detection electrode 3 of delayed phase unit 6
End, and the advanced unit 5 of phase and delayed phase unit 6 are in parallel.
Here, the advanced unit 5 of phase carries out look ahead to electromotive force.Specifically the advanced unit 5 of phase includes parallel connection
Capacity cell and resistive element, electromotive force is received in capacity cell side, sends out the electromotive force handled well in resistive element side
See off.Here, because capacity cell has capacitive, it is possible to make electromotive force advanced.
Here, delayed phase unit 6 carries out hysteresis processing to electromotive force.Specifically delayed phase unit 6 includes parallel connection
Inductance element and resistive element, electromotive force is received in inductance element side, sends out the electromotive force handled well in resistive element side
See off.Here, because inductance element has perception, it is possible to lag electromotive force.
Reference picture 2, present embodiments providing a kind of electromagnetic swirl flowmeater includes control unit 7, and control unit 7 is divided
Lian Jie not the advanced unit 5 of phase, delayed phase unit 6 and detecting electrode 3.Here control unit 7 can be single-chip microcomputer,
Computer program can also be departed from, rely on hardware circuit to realize.Specifically, reference picture 2, control unit 7 include adder 71
With comparator 72；The input of adder 71 connects the advanced unit 5 of phase respectively and delayed phase unit 6, comparator 72 are distinguished
Connect the output end and detecting electrode 3 of adder 71.Because the advanced unit 5 of phase and delayed phase unit 6 are respectively to electricity
Kinetic potential has carried out look ahead and hysteresis processing, therefore, by both phases of contrast, in situation about not influenceed by conductor fluid
Under, both phases can be completely counterbalanced by, and the electromotive force obtained in theory is consistent with the electromotive force that detecting electrode 3 detects.Phase
Anti-, in the case where being influenceed by conductor fluid, both phases cannot be completely counterbalanced by, the electromotive force obtained in theory and inspection
It is inconsistent to survey the electromotive force that electrode 3 detects.Therefore, the result that both are added by contrast can be sentenced with original electromotive force
Break detection result it is whether accurate.
