PTFE lined anti-corrosion metal tube float flowmeter

Description :

　　PTFE lined anti-corrosion metal tube float flowmeter

　　This product mainly consists of three basic parts: 1. Measuring tube body; 2. Cone shaped float; 3. Indicator. The displacement of the float is proportional to the flow rate, and through a magnetic coupling system, the displacement of the float is transmitted to the indicator in a non-contact manner to indicate the flow rate.

　　1、 Working principle:

　　The measured medium flows through the measuring tube from bottom to top, generating a differential pressure at the upper and lower ends of the float to form an upward force. When the upward force on the float is due to the weight of the float immersed in the flowing fluid, the float rises, and the annular gap area increases accordingly. The fluid flow at the annular gap rapidly decreases, and the pressure at the upper and lower ends of the float decreases. The upward force acting on the float decreases until the upward force is balanced with the weight of the float immersed in the fluid, and the float stabilizes at a certain position. The height of the float position corresponds to the flow rate of the measured medium. The float is equipped with magnetic steel, and when the float moves up and down with the medium, the magnetic field changes with the movement of the float.

　　3、 Installation precautions:

　　1. The metal tube float flowmeter must be installed on a vibration free pipeline. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2 °. When installed horizontally, the horizontal angle is better than 2 °;

　　2. For the convenience of maintenance, replacement of flow meters, and cleaning of measuring pipelines, metal tube float flow meters installed on process pipelines should be equipped with bypass pipelines and bypass valves;

　　3. There should be a straight pipe section with a length of at least 5 times the pipe diameter at the entrance, and a 250mm straight pipe section at the outlet;

　　4. If the medium contains ferromagnetic substances, a magnetic filter should be installed; If the medium contains solid impurities, it should be considered to install a filter between the valve and the straight pipe section;

　　5. When used for gas measurement, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to ensure stable operation of the float.
