Easy to use Glass Rotameter 

Glass rotor flowmeter (hereinafter referred to as flowmeter) is one of the instruments used to measure the flow of single-phase media such as non-turbid liquids and gases. The instrument has the advantages of simple structure, easy maintenance and use, and low price. Mainly used in chemical industry, petroleum, light industry, medicine, fertilizer, chemical fiber, electric power, metallurgy, food, sugar, fuel, papermaking, environmental protection and scientific research departments. Working principle and structure The measuring part of the instrument consists of a vertically installed glass cone tube and a float inside the tube. The big end of the tapered tube is upward, and the float moves up and down along the axis of the tapered tube with the flow rate. When the fluid passes through the tapered tube from bottom to top, due to the action of the fluid, a differential pressure is generated on the upper and lower end surfaces of the float, and the float rises under the action of this…
