Insertion flowmeter is a type of flowmeter classified according to its structural form, which includes various flowmeters with different working principles. Insertion flow meters have made significant progress, and from the perspective of the overall development trend of flow meters, they have strong vitality and occupy an important position among many flow meters.

The working principle of the plug-in flowmeter is based on Faraday's law of electromagnetic induction. In an electromagnetic flowmeter, the conductive medium inside the measuring tube is equivalent to a conductive metal rod in Faraday's test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, an induced voltage is generated. The induced voltage generated by measuring the two electrodes inside the pipeline. The measuring pipeline achieves electromagnetic isolation from the fluid and measuring electrodes through non-conductive lining (rubber, Teflon, etc.).

Application: Power generation and cogeneration, heating industry; Aviation, aerospace, shipbuilding, nuclear energy, and weapons industries; Mechanical, metallurgical, coal mining, and automobile manufacturing industries; Petroleum and chemical industries; Pharmaceutical, food, and tobacco manufacturing industries; Forest industry, agricultural reclamation, and light industry.

The WJ-5G01 series ultrasonic flowmeter host can be divided into wall mounted, disc mounted, explosion-proof, etc;

Overcoming the influence of a small amount of sediment, suspended particles, and bubbles on the signal, the accuracy of flow measurement has been improved, making it particularly suitable for flow measurement in large-diameter pipelines.

Using specialized drilling tools to install sensors under pressure without stopping water supply, the unique disassembly and installation method under pressure does not affect normal production, and online replacement and maintenance can be completed at any time.

Solved the problem of abnormal measurement caused by weak signal of external clamp sensors when scaling or severe corrosion occurs on the inner wall of pipelines. Compared to other types of flow meters (such as electromagnetic flow meters), it has a higher cost-effectiveness on large-diameter pipelines.
