Product Overview SEMF Series Electromagnetic Flowmeters, also known as megameters, are instruments used for measuring the flow rate of conductive fluids. They operate based on Faraday's law of electromagnetic induction, where a magnetic field is applied to the fluid and the induced voltage is proportional to the velocity of the fluid. These flowmeters are widely used in various industries for their high accuracy, reliability, and compatibility with a wide range of fluid types.

Key Features:

Non-Intrusive Flow Measurement : SEMF Series Electromagnetic Flowmeters offer a non-intrusive flow measurement technique, as they do not have any moving parts that come into contact with the fluid. This eliminates the risk of mechanical wear and minimizes pressure drop.

  1. High Accuracy: SEMF Series Electromagnetic Flowmeters provide excellent accuracy in measuring flow rates, typically within ±0.25% to ±0.5% of the measured value. This high level of accuracy ensures precise monitoring and control of fluid flow in various applications.

  2. Suitable for Conductive Fluids: SEMF Series Electromagnetic Flowmeters are designed for measuring the flow of conductive fluids, including water, wastewater, chemicals, slurries, and liquids with low conductivity. They are not suitable for non-conductive fluids such as oil or hydrocarbons.

  3. Bi-Directional Flow Measurement: SEMF Series flowmeters can measure flow rates in both forward and reverse directions, making them ideal for applications where flow reversal can occur.

  4. Wide Range of Pipe Sizes: SEMF Series Electromagnetic Flowmeters are available in various sizes, ranging from small pipe diameters to large industrial pipelines. This allows for easy integration into existing piping systems and a wide range of application scenarios.
