Insertion-type Electromagnetic Flowmeter
The insertion-type electromagnetic flowmeter is used to measure conductive fluid flow in municipal water supply, steel, petroleum, chemical, power, industrial, water conservancy, and water resources management sectors. It can also measure corrosive conductive liquids such as acids, alkalis, and salt solutions.
Product Overview:
The insertion-type electromagnetic flowmeter consists of an insertion sensor and converter. It is suitable for measuring flow and total volume of various conductive liquids (including acid, alkaline, salt solutions, water, wastewater, and corrosive liquids) with conductivity ≥5μs/cm across industrial, agricultural, water conservancy, environmental sewage monitoring, and urban water supply applications. Compared to pipeline-type flowmeters, this insertion-type design remains unaffected by changes in fluid density, viscosity, temperature, pressure, and conductivity, offering an extensive measurable flow range. It accommodates industrial pipe diameters up to 3 meters, featuring strong anti-interference capabilities and reliable performance. The device displays real-time flow and cumulative flow, supporting data remote transmission, wireless control, alarm functions, and more.
Performance Features:
· Corrosion-resistant all-stainless steel construction: Compact size, lightweight, long lifespan, easy installation, and low installation cost
· Sturdy design without moving parts: Durable operation, reliable measurement, and excellent anti-interference capability
· Near-zero pressure loss: Allows installation and removal without interrupting water flow under low pressure or pressurized conditions
· Extensive flow measurement range: Full-scale flow velocity in pipelines can be set between 1m/s to 10m/s, with linear signal output proportional to flow rate
· Insertion structure: Ideal for existing pipeline measurements and convenient instrument maintenance
· Advanced low-frequency square wave excitation: Stable zero point, strong anti-interference capability, and reliable operation
· Self-check and self-diagnosis with alarm functions
· Supports digital communication protocols: RS485, RS232, Hart, Modbus, Profibus-DP (optional configurations)
