1. How to remove an oxygen flowmeter
The core process for correctly disassembling an oxygen flowmeter is to first turn off the main valve of the oxygen cylinder or the power supply of the oxygen generator during the backup operation, slowly release the residual pressure in the pipeline, and then hold the flowmeter with both hands and rotate it clockwise to remove it. Forcefully unplugging may damage the interface components, and ordinary threaded interfaces require 3-5 revolutions to separate. Specific operating precautions
1. Confirm that the gas source is turned off: the top valve of the medical oxygen cylinder should be tightened clockwise, and the oxygen generator needs to cut off the power first. At this time, the flow meter float will completely fall to the zero mark
. If encountering a special buckle design, it is necessary to first press the interface circular locking pin and then pull it outward. The interface of a flow meter that has been used for more than 3 years may experience oxidation adhesion. It can be lubricated with a small amount of medical Vaseline before operation. The threaded interface of medical grade oxygen equipment generally adopts the national standard G5/8 specification, while American standard interfaces are commonly used in household oxygen concentrators. If the sealing gasket is deformed after disassembly, it should be replaced in a timely manner. Observe whether the CE certification mark is printed on the back of the flowmeter. Regular products will have anti slip thread design at the metal interface.

>3. Is the bead of the oxygen cylinder viewed from the top or bottom?
The reading method of the float (bead) of the oxygen cylinder needs to be determined according to the shape of the float and specific equipment.. For conical buoys: Reading method: When inhaling oxygen, the oxygen flow rate value should be read based on the scale indicated at the top of the buoy. Attention: Ensure that the flow meter is perpendicular to the ground to obtain accurate readings. For spherical buoys: Reading differences: The reading method for spherical buoys may vary depending on the equipment and manufacturer. One viewpoint is that the reading of the scale line at the maximum cross-section of the float should be taken as the standard. Another viewpoint: It is necessary to refer to the position of the "0" mark at rest to determine the oxygen flow rate during oxygen inhalation. Specific equipment regulations: Some brands of oxygen inhalers require horizontal observation based on the center of the float. Summary and Suggestions: Due to possible differences in the reading methods of oxygen cylinder buoys among different devices and manufacturers, it is recommended to carefully read the specific equipments user manual before use. In case of uncertainty or doubt, it is necessary to consult the manufacturer or professionals in a timely manner to ensure accurate reading of the oxygen flow rate value, guarantee the effectiveness and safety of oxygen inhalation. During use, attention should also be paid to maintaining the flowmeter in a vertical position with the ground to avoid reading errors caused by angle issues.
