Road.
And electromagnetic flowmeter has the advantages of precision is high, and stability is good, high reliablity, long service life, and in lining
Portion is that siphunculus is not easy blocking pipeline, therefore considers that electromagnetic flowmeter is selected to replace magnetoelectric flowmeter.
But the reason of that there are stress levels is low for the electromagnetic flowmeter of conventionally form, contour structures and installation form can not also replace
For existing magnetoelectric flowmeter.
A kind of electromagnetic flowmeter of built-in electrode form has thus been invented, contour structures are consistent with existing magneto-electric,
In the case where not changing oil exploration equipment, original magnetoelectric flowmeter can be easily replaced.This built-in electrode formula
Electromagnetic flowmeter precision is resistance to be pressed in the high pressure flow measurement of 40-50MPa satisfaction on site at 1.5 grades.
Summary of the invention
The purpose of the present invention is to provide electromagnet flow meter sensor built-in electrodes and lining encapsulating structure, solve existing
Electromagnetic type flow meter be applied to field of petroleum exploitation, the inadequate defect of compressive resistance.

Compared with prior art, the beneficial effects of the present invention are:
Electromagnet flow meter sensor built-in electrode provided by the invention and lining encapsulating structure, by opening up key in lining
Slot, dress matches flat key in keyway, and lead is mounted between flat key and keyway, meanwhile, electrode is mounted on and is opened up on flat key
In mounting hole, which makes electrode directly be embedded in lining, so that the installation of electrode does not need to seal, improves electromagnetism
The compressive resistance of flowmeter entirety.
Further, keyway is symmetrical, guarantees that two electrodes are symmetrically installed.It says, surveys from electromagnetic flowmeter survey principle
Examination electrode must symmetrically be fixedly mounted, location error caused by will not testing the electromotive force in magnetic field.
Further, electrode structure feature, the different round table surface of designed size, makes it be fixed on the inner hole of electrode tip holder
In, electrode is wrapped among lining by keyway fixed form.
