Plastic plastic tube rotameter with a light weight, unbreakable, non-toxic, tasteless, easy to use features. Mainly used in chemical industry, light industry, medicine, food, environmental protection and other sectors, for single-phase liquid flow measurement of non-pulsating flow. Flowmeter principle and structure of the plastic flow meter rotor structure shown: mainly by the small end down, the big end up the clear plastic cone and tube vertically mounted within the cone of the float can move up and down as the measuring element, and nuts, receivership, only stalls and "O" rings and other accessories. When the fluid flows from bottom to top within the cone, the upper and lower pressure difference is generated in the float, the float rises, the float when the pressure of gravity, buoyancy and the viscous forces in equilibrium, the float in the rest position, when the flow rate changes, flowing between the cone and the float at the annulus fluid flow rate changes, changes in the pressure difference between the corresponding float up and down, as the float moves up and down, so the height of the float can be used as a measure of the resting position of traffic. Plastic rotor flowmeter design outline drawing installation (1) Prior to installation, the instrument should be within the foam support tool needle nose pliers to gently put it out, and then re-installed it, during installation, pay attention to the rubber gasket Whether mounted on the takeover of the tank to prevent leakage. (2) meter interface, available in matching ABS plastic pipe, or PVC plastic pipe, connected with a special glue, can also be used after a plastic flange connection, and then the metal flange connection. (3) the meter must be installed vertically, should be no significant tilt, its installation height, should be easy to float readings; when reading, sight should be level with the float. (General Standard: optimal flow meter required for 50% -70% of maximum flow, try not to use the highest number) (4) in the meter downstream of import and export shall ensure that there is five times the meter straight pipe diameter. (5) the measured fluid pressure to be stable, such as unstable fluid pressure can cause fluctuations in the float, can not be measured correctly, the flowmeter upstream value should be set to a buffer or filter. Use (1) meter, when used, should slowly open the upstream valve to open, and then adjust the flow meter with control valve downstream. (To prevent sudden impact float upward and damage to the instrument, to avoid drastic changes in fluid temperature measured using the meter leaks are found, usually ring dislocation or failure should be corrected or replaced.) Stop using the meter, should be Slowly close the upstream valve, then close the flow control valve downstream of the meter. (2) When the conical tube and float contamination, should be cleaned. (3) regularly check the meter error, once outside the specified error, the float should be reversed and the cone, or re-calibration. (4) when the meter scale measured fluid and inconsistent, showing the value required to be corrected according to the measured fluid.
