Problems solved by technology

[0002] At present, the commonly used water meter is the impeller-based meter, which uses the water flow to impact the impeller, obtains the flow velocity and sends the corresponding flow information to the circuit, and can display the fluid flow. However, this kind of water meter has a complex structure, high cost, and is not easy to disassemble. The initial flow rate is large, and the water quality requirement is high, which brings inconvenience to production and use.

Abstract

The invention discloses an insert type water meter, and belongs to the field of water supply measuring instrumentation. The insert type water meter consists of a coaxial cable, a copper tube, a stainless steel shell, a polarity detector, a permanent magnet, a magnetic field test coil, positive and negative electrodes, a lead wire plate, a shield plate, a coil brace, a plastic piece and an intelligent part; and the insert type water meter is mainly used in the field of flow measurement. The insert type water meter has a simple structure, small volume and low cost, changes to utilize the permanent magnet and the electrodes as a basic meter, has the advantages of reliable performance, flexible control, uneasy blockage and so on, and has quite important significance.

Description

Technical field [0001] The invention belongs to the field of flow measurement, and particularly relates to the related fields of mechanical parts and circuit information transmission technology. Background technique [0002] At present, the water meter is commonly used as the impeller base meter. It uses the water flow to impact the impeller, knows the flow rate and sends the corresponding flow information to the circuit, which can display the fluid flow. However, this kind of water meter has a complex structure, high cost, and is difficult to disassemble. The starting flow is relatively large, and the water quality requirements are high, which brings inconvenience to production and use. Summary of the invention [0003] In order to solve the above-mentioned technical problems, the technical problem to be solved by the present invention is to provide a plug-in water meter which is directly inserted into the pipeline and uses permanent magnets and electrodes as the base meter. The ...
