Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] figure 2 It is a schematic diagram of the general structure of an existing magnetic eddy street flowmeter, mainly including a small measuring tube 13, a triangular cylinder 11, an upper magnet 10, a lower magnet 12, an electrode 9, insulating pads 7 and 8, and a locking mechanism for pressing the electrode 9. The nut 6, the insulating sleeve 5, the nut 3, the signal processing converter 1, the signal line 2 connected to the signal processing converter 1, etc. are composed.

[0025] see Figure 3-1 with Figure 3-2 The large-caliber magnetic vortex flowmeter comprises a large-diameter measuring tube 14 and a small-caliber magnetic vortex flowmeter, and the small-caliber magnetic vortex flowmeter is inserted into the large-caliber measurin...

Abstract

The invention discloses a large-caliber magnetoelectric vortex shedding flowmeter which comprises a large-caliber sounding pipe and a small-caliber magnetoelectric vortex shedding flowmeter and is characterized in that the small-caliber magnetoelectric vortex shedding flowmeter is inserted into the large-caliber sounding pipe. The caliber of the large-caliber magnetoelectric vortex shedding flowmeter of the invention can achieve DN600 at most, even larger. Under the situation of the same caliber and flow speed, compared with the original magnetoelectric vortex shedding flowmeter, the flowmeter of the invention can release with high frequency and strong signals, that is, the novel flowmeter has the advantages of high measuring accuracy, low measurement lower limit, and short straight pipe sections installed at the front and the back; under the premise of guaranteeing the sounding pipes with the same specification are interchangeable (guaranteeing that the sounding pipe used for detection and the sounding pipe of a user are consistent), and under the situation of keeping the direction of installing the small-caliber sensor to be consistent, the core part of the small-caliber sensor is returned to the OEM or the monitoring and managing department, thus solving the problem of the difficult sending for detection of the large-caliber magnetoelectric vortex shedding flowmeter and greatly reducing the assembly and disassembly cost of the sending for detection.

Description

technical field [0001] The invention relates to a vortex flowmeter, in particular to a large-diameter magnetoelectric vortex flowmeter designed by using the "Karman" vortex principle and Faraday's electromagnetic induction principle for measuring conductive liquid media. It can be widely used in the measurement of conductive liquid flow in petroleum, chemical, metallurgy, textile, food, pharmaceutical, papermaking and other industries, as well as in environmental protection, municipal water supply and drainage, water conservancy construction, river dredging and other fields. Background technique [0002] The magnetic vortex flowmeter is the same as other vortex flowmeters. It uses the "Karmen" vortex principle, which is different from the piezoelectric detection method of most vortex flowmeters. It adopts a new detection method of electromagnetic induction. Vortex flowmeter. When the conductive medium flows through the triangular prism 10 at a certain speed, an alternately ...
