The buoy level gauge consists of five parts: buoy, connecting wire, guide pulley, weight pointer, and display scale. It is suitable for low-cost liquid level measurement of flat bottom cone cover and dome container for tanks, tanks, oil fields, oil depots, etc. stored in corrosive media in petrochemical systems, and water towers (water tanks) for general enterprises and civil buildings. Solve the difficulty of manually measuring fluid level. The level gauge is designed based on the principle of force balance. When the liquid level is at a certain height, the weight of the buoy is W, the weight of the weight hammer is W1, the buoyancy force of the buoy immersed in the liquid is F, and the system friction is (. In equilibrium: WF-W1-f=0 ) When the liquid level rises, the buoyancy F increases, W, W1, and f do not change, and the above formula breaks down, and the dangling hand falls. Until the F force is reduced to its original value, a new balance is established. For example, F force has been increasing, that is, the liquid level has been on the long, the pointer has been falling. Conversely, if the liquid level drops, the Weight Indicator will rise to indicate the height of the liquid level.
Buoy level gauge installation and maintenance:
1. It must be vertical to ensure that the magnetic float moves freely up and down in the main tube.
2. Shut-off valves should be installed between the container and the container to cut off the materials for cleaning and inspection.
3, around the cylinder does not allow a magnet near, otherwise it will directly affect the normal operation of the level gauge.
4. After the installation is completed, the magnetic steel must be used for calibration. The magnetic column of the display panel is guided once, so that the red below the zero position is displayed in red, and the white position above the zero position is displayed.
5, when the float is loaded, it should be noted that the heavy end with a magnetic end up, can not be inverted.
6. There should be no solid impurities and magnetic impurities in the cylinder to avoid jamming and weakening the buoyancy of the float.
