The sewage-type electromagnetic flowmeter is a flow measurement instrument specifically designed for complex liquids such as municipal sewage, industrial wastewater, and agricultural wastewater, which contain solid particles, suspended matter, and corrosive components.

The sewage-type electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductive liquid flows through a magnetic field, an induced electromotive force is generated, and its magnitude is proportional to the flow velocity.

• No flow-blocking components: There are no moving parts inside the measuring tube, resulting in no pressure loss and a lower requirement for straight pipe sections (upstream ≥ 5DN, downstream ≥ 3DN).
• Strong resistance to impurities: Suitable for wastewater containing solid particles and suspended matter, and is less prone to clogging.
• High protection grade: With IP65/IP68 protection grade, it is suitable for underground and submerged working environments.

• Straight pipe sections: Upstream ≥ 5DN, downstream ≥ 3DN (DN is the pipe diameter).
• Position: Avoid the highest point of the pipe (to prevent air bubbles), and the pump inlet (to prevent negative pressure). Vertical installation is preferred (flow direction from bottom to top).
• Grounding: Must be reliably grounded. For non-metallic pipes, a grounding ring should be installed.

• Regularly clean the electrodes and liners to prevent scaling or corrosion.
• Check the sealing of the cable joints to avoid signal interference from damp environments.

• Sewage treatment plants: Measure the flow of influent, effluent, and sludge return, etc., to provide data support for process optimization.
• Industrial wastewater monitoring: Monitor the wastewater discharge of industries such as chemical engineering, metallurgy, and papermaking to ensure compliance.
• Agricultural irrigation: Measure the water flow in the irrigation system to achieve water conservation and emission reduction.
• Environmental monitoring: Connect with environmental protection departments, upload data in real time, and achieve remote monitoring and alarm.
