Insertion Electromagnetic Flowmeter For Sewage / Tap Water Measurement
Insertion Electromagnetic Flowmeter For Sewage And Tap Water Measurement
An insertion electromagnetic flowmeter is a type of instrument that measures the flow of conductive liquids by inserting a sensor through an opening in the pipe. It is particularly suitable for large-diameter pipes, situations where installation during flow interruption is difficult, and industrial environments containing a small amount of solid particles or high-viscosity media.
- Non-interruption installation: The "pressure tapping" technology is adopted, allowing installation without production halt or process interruption. For large pipelines, this avoids significant production loss.
- Strong adaptability to pipe diameters: One model of the insert-type flowmeter can cover a very wide range of pipe diameters (e.g., DN80 to DN3000), offering excellent cost performance. The larger the pipe diameter, the more obvious the cost advantage over pipe-type flowmeters.
- Minimal pressure loss: The sensor rod offers minimal obstruction to the fluid flow, generating almost no additional pressure loss and achieving good energy-saving effects.
- Convenient maintenance: The sensor rod can be pulled out from the pipeline for inspection or replacement by closing the ball valve without system shutdown.

| Cost | Low (especially for large diameters) | High (cost increases sharply with diameter) |
| Installation | Convenient, can be installed without interrupting flow | Complex, requires pipeline disconnection |
| Diameter | Large (DN80 and above) | Full coverage of large, medium and small diameters |
| Maintenance | Convenient, can be maintained without interrupting flow | Requires shutdown for maintenance |
| Applicable pipe materials | Only conductive pipes | Any pipe (grounding required) |
| Application positioning | Process monitoring, energy management, auxiliary measurement for large flow trade handover | Accurate measurement, trade settlement, formula control |
The insertable electromagnetic flowmeter is an economical and practical flow measurement solution. It sacrifices some accuracy in exchange for excellent installation convenience and cost-effectiveness on large-diameter pipes.
When making a choice, please keep in mind its positioning: it is a "powerful tool" for flow monitoring and management of large-diameter pipes, rather than a "ruler" for high-precision trade settlement. If your application scenario does not have high requirements for accuracy, but involves large-diameter pipes, difficult installation and a limited budget, then the insertable electromagnetic flowmeter is an extremely ideal option.
