High-maintainability right-angle electromagnetic flowmeter

Abstract

The present invention discloses a high-maintainability right-angle electromagnetic flowmeter. The high-maintainability right-angle electromagnetic flowmeter comprises a flowmeter main shell; the lowerend of the flowmeter main shell is detachably provided with a first sensor; the right upper end of the flowmeter main shell is detachably provided with a second sensor; an elbow pipe is arranged in the object accommodating cavity of the flowmeter main shell; a right-angle flow passage is arranged in the elbow pipe; a first fluorine plastic liner measurement pipe is embedded in the first sensor; afirst measurement channel is arranged in the first fluorine plastic liner measurement pipe; the local position of the first measurement channel is provided with a first sensor electrode; a first ceramic measurement pipe is embedded in the second sensor; a second measurement channel is arranged in the first ceramic measurement pipe; the diameter of the right-angle flow passage and the diameter ofthe second measurement channel are identical; and the diameter of the first measurement channel is greater than the diameter of the right-angle flow passage. With the above technical schemes adopted,the high-maintainability right-angle electromagnetic flowmeter has the advantages of reasonable structural design, simple structure, good sealing performance, long service life, capability of improving measuring precision and a range ratio, convenient maintenance operation and high practicability.

Description

technical field [0001] The invention relates to the technical field of electromagnetic flowmeters, in particular to a high-maintenance right-angle electromagnetic flowmeter. Background technique [0002] Accurate measurement of flow rate is an important field of automation control, and it is also a difficult problem that automation engineers must devote great efforts to continuously solve. In particular, problems such as non-full pipe, small flow rate, low accuracy, small measuring range, and serious damage due to high pressure differential erosion have been long-standing problems. At the same time, users have higher and higher maintenance requirements for instruments. However, the existing right-angle electromagnetic flowmeter still has shortcomings: unreasonable structural design, complex structure, low measurement accuracy, small range ratio, easy leakage, short service life, troublesome maintenance and poor practicability. Contents of the invention [0003] In view of...
