[0002] Insertion type electromagnetic flowmeter is used to measure the flow of conductive fluids in tap water, steel, petroleum, chemical industry, electric power, industry, water conservancy, water administration and water resources departments. It can also measure corrosive conductive liquids such as acid, alkali and salt. Insertion type electromagnetic flowmeter is composed of insertion type electromagnetic flowmeter sensor and insertion type electromagnetic flowmeter converter, which is used to measure the volume flow of various conductive liquids in pipelines.

In addition, since the existing insertion electromagnetic flowmeter is installed on the pipeline by using multiple pipe bolts, it is also inconvenient to disassemble and install the flowmeter. For this reason, we propose an insertion electromagnetic flowmeter. Utility Model Content
