1. Is the bead on the oxygen cylinder visible from above or below?
The bead on the oxygen cylinder (float indicator) must be placed below. When the oxygen cylinder is opened, the small beads in the float type flowmeter will suspend with the flow of oxygen. If the beads stay above, it indicates that they have not been installed correctly or there is abnormal gas pressure, which may result in inaccurate readings or wheel breakage during oxygen supply. 1. The transparent tube of the oxygen cylinder flowmeter is equipped with metal/plastic floating beads. When gas flows, the floating beads are lifted up, and the flow rate value is determined by observing the corresponding scale line of the floating beads. If the bead is located above, it is usually caused by high flow rate, deviation in verticality of the tube body, or component inversion. 2. Correct installation method of rubber tubing. When connecting the humidification bottle to the flow meter, ensure that the flow meter module where the bead is located is at the bottom of the entire device. After opening the oxygen valve, slowly rotate the flow adjustment knob and observe that the bead rises steadily from below to the corresponding scale line, which is normal Abnormal troubleshooting: If the bead is always above: ① Check if the pipeline is blocked or if the water level in the humidification bottle is too high ② Confirm if the sealing ring of the connection interface has fallen off ③ Stop oxygen supply and re tighten the connection between the flowmeter and the bottle body. First time users often mistakenly install the entire flowmeter upside down. It is recommended to visually observe and confirm that the scale numbers on the transparent tube are arranged in a
2. How to check the flow rate with an oxygen flowmeter
The way to check the flow rate with an oxygen flowmeter is through a pressure gauge.
. If the pressure gauge on a regular bottle is full, the pressure is around 10, and the amount of oxygen remaining in the bottle can be determined based on the scale and proportional relationship. If the pressure is below 1, it is recommended not to inhale the Wheel Wu Xu again, as there may be impurities. The oxygen flowmeter consists of a flow sensor and a flow calculator, with sensing components using disposable packaging technology and a service life of 35 years. Working principle of oxygen flowmeter: When the medium flows in the measuring tube, due to its own kinetic energy and pressure difference with the target plate, a force is generated on the target plate, causing a slight displacement of the target plate. The magnitude of the force is proportional to the square of the medium flow velocity. Its mathematical formula is: F=Cd · A ·ρ· V2/2F: the force acting on the target plate Cd: the fluid resistance coefficient A: the axial projection area of the target plate on the measuring tube ρ: the density of the medium under working conditions V: the characteristic flow velocity of the medium in the measuring tube. The force acting on the target plate is transmitted through the target rod, causing a slight change in the elastic body of th
