 Working Principle of Metal Tube Flowmeter
The working principle of the metal tube flowmeter is based on the principles of fluid mechanics and physical mechanics, and mainly involves the following aspects:
When the fluid flows through the measuring tube, it will exert a force on the rotor in the tube, and the magnitude of this force is proportional to the flow rate of the fluid.
A rotameter consists of a conical tube and a rotor that can move freely up and down along a centerline. When the fluid enters the tapered tube and flows through the rotor,
 it creates a downward pressure difference below the rotor and an upward thrust above the rotor.
The buoyancy of the rotor in the fluid and its own gravity are also important factors affecting the position of the rotor. When these forces are balanced, the rotor floats stably in a specific position within the tapered tube.
The position of the rotor in the tapered tube has a one-to-one correspondence with the flow rate flowing through the tapered tube. By measuring the position of the rotor, the flow rate of the fluid can be deduced.
