Embodiment Construction

[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0016] combine Figure 1~4 , The electromagnetic vortex flowmeter of the present invention consists of a flow channel 12 with a flat key-shaped cross section, two permanent magnets 4, 13, electrodes 7, several sealing and insulating devices, and upper and lower glands 9, 11. The shape of the flowmeter is the same as the installation space. In the present invention, the shape of the flowmeter is a section of ring, and the two sides of the ring are semicircles tangent to the two circles forming the ring.

[0017] This kind of integrated fixing method abandons the lock nut used to fix the upper magnet and the electrode in the general fixing method, the compression nut used to fix the signal line, and directly sets the fixed ladder on the upper gland 9, and uses the ladder to align the magnet. , electrodes and signal wires are compressed and fixed.

The main flow channel member is in a hollow structure, the outer wall on the upper portion of the main flow channel member is provided with a first mounting groove, the outer wall of the lower portion of the main flow channel member is provided with a second mounting groove, the first mounting groove is provided with an upper permanent magnet, the second mounting groove is provided with a lower permanent magnet, the upper pressing cover and the lower pressing cover are fixed together and coat the upper permanent magnet, the main flow channel member and the second permanent magnet, the upper portion of the electrode is located in the upper pressing cover, the lower end of the electrode penetrates the upper permanent magnet and the main flow channel member and is located in the main flow channel member, an insulation pad is mounted between the electrode and the upper pressing cover, a seal sleeve is mounted between the electrode and the main flow channel member, a signal line mounting hole is formed in the upper pressing cover and is provided with a signal line, and the signal line is connected to the electrode; a triangular prism shape vortex generator is arranged in a main flow channel, and the upper pressing cover is provided with flow inlet holes communicated with the main flow channel. By the aid of the inserting electromagnetic vortex shedding flowmeter, the size can be reduced effectively.

Description

technical field [0001] The invention relates to a flow measuring device. Background technique [0002] At present, most vortex flowmeters use piezoelectric sensors, which are susceptible to external vibration interference and affect measurement accuracy. Electromagnetic vortex flowmeters use the principle of electromagnetic induction to overcome the shortcomings of weak anti-interference ability of vortex flowmeters. [0003] In fields such as petroleum water injection, it is necessary to measure the accurate flow rate of the water injection well. The flow meter must be inserted into the water injection valve and driven into the well. The installation space of the flow meter is limited, and the flow meter is generally required to have a smaller volume and a wider width. The measurement range and high pressure resistance are required, but the small diameter of the current electromagnetic vortex flowmeter is limited, and further improvement is needed. [0004] In the usual el...
