pyörrevirtamittarit

Pyörrevirtamittarit, also known as eddy current flowmeters, are devices used to measure the flow rate of liquids or gases. They operate based on the principle of inducing eddy currents in a conductive fluid and then measuring the magnetic field generated by these currents. As the fluid flows through the meter, it disturbs a magnetic field, creating a voltage that is proportional to the flow rate. This voltage can then be converted into a flow rate reading.

These instruments are characterized by their robust construction and lack of moving parts, making them suitable for a wide range of applications, including in harsh environments. They are non-intrusive in the sense that they do not impede the flow of the fluid significantly, which can be advantageous for sensitive or viscous fluids. The accuracy of pyörrevirtamittarit can be influenced by factors such as the electrical conductivity of the fluid, temperature, and the presence of impurities.

Pyörrevirtamittarit find use in various industries, such as chemical processing, oil and gas, and water treatment. They are employed for monitoring and controlling flow rates in pipelines, tanks, and processing equipment. Their ability to measure flow without requiring direct contact with the fluid makes them a reliable choice for applications where contamination or wear of mechanical components is a concern. The technology relies on Faraday's law of induction to generate a measurable electrical signal from the fluid's motion.
