Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a sensor assembly of an electromagnetic flow meter. Background Art

[0002] An electromagnetic flow meter is an instrument that applies the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the electromotive force induced when the conductive fluid passes through an externally applied magnetic field. It is widely used in metering instruments such as water meters.

[0003] For existing electromagnetic flow meters, due to their large size and relatively large installation space requirements, usually a single electromagnetic flow meter requires a separate installation box. In addition, the magnetic coil and the water flow are not compact enough, and the induction of the magnetic field on the water flow is sometimes not sensitive enough, resulting in a decrease in the accuracy of the electromagnetic flow meter.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a sensor assembly of an electromagnetic flowmeter, including a housing 1. A fluid passage 2 is provided along the length direction at the center of the housing 1. An induction assembly is provided in the middle section of the housing 1. Mounting feet 3 are provided at both ends of the housing 1, and the mounting feet 3 can mount the housing 1 in a suitable position for monitoring. The housing 1 is in the shape of a hollow cuboid, and flanges are provided at both ends thereof. Both ends of the fluid passage 2 are provided on the flanges. The fluid passage 2 includes an intermediate passage 21. Two sections of the intermediate passage 21 are connected with a water inlet pipe 22 and a water outlet pipe 23. The water inlet pipe 22 and the water outlet pipe 23 are symmetrically arranged at both ends of the intermediate passage 21, and both the water inlet pipe 22 and the water outlet pipe 23 are in the shape of a flared opening. The narrow openings of the water inlet pipe 22 and the water outlet pipe 23 are communicated with the intermediate passage 21, and the induction assembly is communicated with the intermediate passage 21. When water flows through the fluid passage 2, the shape of the fluid passage 2 can enhance the water flow velocity, make the water flow thinner and the flow velocity faster. Therefore, the induction assembly can more accurately measure the water flow rate.

[0020] In an embodiment of the present utility model, the induction assembly includes a mounting frame 4, a magnetic coil 5 and an induction head 6. The mounting frame 4 is mounted on the housing 1, and the magnetic coil 5 is provided on the mounting frame 4.

[0021] Further, there are two groups of magnetic coils 5, which are respectively provided at both ends of the inner cavity of the mounting frame 4.

[0022] Further, the mounting frame 4 includes a first mounting component and a second mounting component. Both the first mounting component and the second mounting component include a bottom plate 41. Connecting plates 42 are hinged at both ends of the bottom plate 41, and the two groups of connecting plates 42 are clamped with each other. This makes the whole mounting frame 4 easy to disassemble. When installing, no additional fasteners such as screws are required, which is convenient for installation.

[0023] In an embodiment of the present utility model, a bracket mounting groove 11 is provided on one side of the housing 1 opposite to each other, and the connecting plate 42 is clamped in the bracket mounting groove 11. The bracket mounting groove 11 can not only prevent the mounting frame 4 from displacing, but also make the outer wall of the connecting plate 42 flush with the housing 1, making the whole present utility model more compact and saving space.

[0024] In an embodiment of the present utility model, a magnetic coil mounting groove 12 is provided on the other side of the housing 1 opposite to each other, and the magnetic coils 5 are respectively mounted in the magnetic coil mounting grooves 12.

[0025] In an embodiment of the present utility model, an induction head mounting seat 13 is provided in the bracket mounting groove 11, and the induction head 6 is mounted on the induction head mounting seat 13. The top end of the induction head 6 is in the shape of a smooth umbrella. After passing through the side walls of the housing 1 and the fluid passage 2, it slightly extends to the inner wall of the fluid passage 2, that is, the bottom edge of the umbrella-shaped top end thereof is connected to the inner wall of the fluid passage 2. When water flows through the fluid passage 2, the top end of the induction head 6 can keenly sense the water flow.

[0026] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
