Insertion Electromagnetic Flow Meters for Large Pipe Retrofitting & Monitoring

  • Insertion-type design for large and existing pipelines

  • No moving parts, reliable operation with minimal maintenance

  • Hot-tap installation possible under low or working pressure

  • Low pressure loss and low energy consumption

  • Wide flow velocity range with linear output

  • Cost-effective solution for medium and large diameter pipelines

  • Strong anti-interference performance with stable zero point

  • Multiple output signals for industrial automation systems

  • Product overview

The plug-in electromagnetic flowmeter consists of a plug-in electromagnetic flow sensor and a matched electromagnetic flow converter, forming a complete flow measurement system for conductive liquids in pipelines.

Designed based on the principle of electromagnetic induction, this flowmeter is ideal for flow measurement in large and medium diameter pipelines, especially for existing pipe networks. The insertion structure allows easy installation and removal without stopping the process under low or working pressure, significantly reducing installation cost and downtime.

With no moving parts and a full-bore measuring concept, the flowmeter provides stable, accurate, and reliable measurement. Its performance is not affected by changes in temperature, pressure, density, viscosity, or conductivity (above the minimum requirement), making it suitable for a wide range of industrial applications.
