Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flow meters, in particular to a glass rotor flow meter. Background Art
[0002] Glass rotameter is a commonly used flow measurement instrument. It is a type of rotameter, mainly composed of a vertically placed glass tube and a float that can move up and down. When the fluid passes through the glass tube, the float is thrust upward, and this thrust is proportional to the flow rate of the fluid. When the flow rate of the fluid increases, the float rises, and correspondingly, the flow rate of the fluid decreases and the float falls. By observing the position of the float in the glass tube, the flow rate of the fluid can be known.
[0003] Chinese utility model patent CN220751251U discloses a filter-type glass rotor flowmeter, which relates to the technical field of glass rotor flowmeters, including a filter box, a filter assembly and a fixed assembly. A water inlet pipe is arranged on one side of the fixed assembly, one end of the water inlet pipe is plugged into the filter box, a glass tube is fixedly connected to the side of the filter box away from the water inlet pipe, the end of the glass tube away from the filter box is fixedly connected to the fixed box, an outlet pipe is plugged into the center of the fixed box, and a float is arranged inside the glass tube. The design of this application filters large particles in the water through a third filter screen, and the second filter screen filters scale in the water. The split design of the cover plate and the sleeve is convenient for disassembly of the third filter screen and cleaning of the second filter screen and the third filter screen. The float is provided with a ball in an internal ring to reduce the friction between the float and the pillar, so that the float of the float is smoother, the corrosion of the float to the float by impurities in the water is reduced, the floating stability of the float is increased, and the measurement result is more accurate.
[0004] However, the existing glass rotor flowmeter cannot quickly eliminate the foam generated by the liquid after the liquid enters it, which causes the foam to adhere to the float and increase the effective volume of the float, resulting in a higher flow value displayed by the flowmeter. In other words, the foam will be mistaken for actual liquid, resulting in inaccurate flow measurement and false flow reports; and the instability of the foam may cause fluctuations in the flowmeter readings, even if the actual liquid flow is stable; this is because the volume of the foam is unstable, and as the foam is generated and burst, it may cause irregular changes in the position of the float in the flowmeter, causing flow fluctuations; affecting the accuracy of the data.
