What Is the Application of Metal Tube Rotameter in the Petroleum Industry

The application of metal tube rotameter in the petroleum industry is extensive. It is an instrument used to measure the velocity of fluid flow by the rotation of the rotor. Also accurate flow measurement is crucial for production, processing, and transportation processes in the petroleum industry. This article will delve into the application of metal tube rotameter in the petroleum industry, including their principles, advantages, application scenarios, and future trends.

What Is the Application of Metal Tube Rotameter in the Petroleum Industry

Principle and Structure

The metal tube rotameter is an instrument based on the measurement of fluid flow velocity through a rotating rotor. Its main components include metal tubes, rotors, sensors, and signal processing units. When the fluid passes through the metal tube, the rotor is driven by the fluid to rotate, and the rotational speed is proportional to the fluid flow velocity. The sensor detects the rotational speed of the rotor and sends the signal to the signal processing unit for processing. It will, ultimately, obtain an accurate measurement of the flow rate.
