Reasonably purchase glass rotameter according to the measuring medium
Dec 22, 2021
The glass rotameter is a commonly used flow measuring instrument. The main measuring element is a vertically installed cone-shaped glass tube and a float that can move up and down. Today, the editor will mainly introduce the glass rotor flowmeter and the selection elements, hoping to help users better apply the product.
Uses of glass rotameter
Glass rotor flow meters are mainly used in chemical industry, petroleum, light industry, medicine, fertilizer, chemical fiber, food, dye, environmental protection and scientific research
It is used to measure the flow of single-phase non-pulsating (liquid or gas) fluid in various departments such as research. The anti-corrosion glass rotor flowmeter is mainly used to detect the flow of corrosive liquids and gaseous media, such as strong acids (except hydrofluoric acid), strong alkalis, oxidants, strong oxidizing acids, organic solvents and other corrosive gases or liquids Flow detection of the medium.
Selection elements of glass rotameter
The glass rotor flowmeter is easy to use and install, the price is also cheap, the work effect is obvious, and the portability and intuitiveness can be seen in many areas of the industry. What we will introduce here is about the types of glass rotor flowmeters, how we should choose them, and their main application areas.
The main measuring element of the glass rotor flowmeter is a vertically installed conical glass tube and a float that can move up and down inside. The end of the conical tube is upward. When the fluid passes through the conical glass tube from bottom to top, a pressure difference is generated between the upper and lower floats, and the float rises under the action of this differential pressure. When the force that makes the float rise is equal to the combined force of the gravity, the float and the viscous force on the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow through the glass rotameter and the rising height of the float, that is, the flow meter area of the glass rotameter, and the position height of the float can be used as a flow measurement. Corrosion-resistant series glass rotors are mainly composed of conical glass tubes, floats, upper and lower bases and supporting parts.
Types of glass rotameters According to the application and scope of application, glass rotameters can be divided into: ordinary type, ribbed vascular type, small flow and small shape type, corrosion-resistant type, laboratory type, heat preservation type, alarm type and resistant Eight series of high pressure type.
