The measuring part of the metal rotameter consists of a cone tube and a conical float. When the fluid flows upward through the tube, the conical float moves upwards and reaches equilibrium at a certain position. At this time, the annulus of the float and the cone tube is kept constant. The annulus area is proportional to the rise height of the float. The measuring part of the metal rotameter consists of a conical tube and a conical float. When the fluid flows up through the tube, the conical float moves upwards and reaches equilibrium at a certain position. The annular gap of the cone tube is kept constant, and the annulus area is proportional to the height of the float rise, and a certain height of the float represents the flow rate of the flow. When the float moves up and down, it is transmitted to the external indicator in the form of magnetic coupling. The pointer of the indicator follows the displacement of the float and the pointer is linearly indicated by the cam plate.

Metal rotor flowmeters need to pay attention to the following when installing and using:
1. The flowmeter must be installed vertically. The measured fluid flows through the cone from bottom to top. The inlet and outlet are guaranteed to have a straight pipe section with 5 times the gauge diameter. For the newly installed pipeline, the pipeline should be cleaned before installation.
2. The valve should be installed upstream of the flowmeter, and the flow regulating valve should be installed at the downstream 5~10 times of the gauge diameter. For small-diameter instruments, filters should be installed upstream. If the measured medium contains magnetic substances, the magnetic filter should be installed in front of the flowmeter.
3. In order to facilitate the repair and replacement of the flowmeter, it is necessary to connect the bypass pipeline when the instrument is installed.
4. The metal rotameter needs to be cleaned regularly, especially when the measured medium is dirty, and the tube and float should be cleaned in time. Perhaps you are also interested in our company's flowmeters.
