Description

Technical Field

[0001] The utility model relates to the technical field of glass rotor flowmeters, in particular to a welded throttling glass rotor flowmeter. Background Art

[0002] Glass rotor flowmeters utilize a certain proportional relationship between fluid flow and the height of the float's rise, that is, the flow area of the glass rotor flowmeter. Therefore, the position height of the float can be used as a flow measurement. Due to its excellent characteristics, it is widely used in various departments such as chemical industry, petroleum, light industry, medicine, food, dyes, and scientific research. The main measuring element of the glass rotor flowmeter is a vertically mounted tapered glass tube with a smaller bottom and a larger top, and a float that can move up and down inside. When the fluid passes through the tapered glass tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under the action of this differential pressure. When the rising force, the buoyancy and viscous lift of the float are equal to the weight of the float, the float is in an equilibrium position. However, traditional equipment requires manual identification of the scale during use, which may result in inaccurate readings. Therefore, we have redesigned a welded throttling glass rotor flowmeter. Utility Model Content
