Overview

Glass rotor flowmeter is mainly used in various departments such as chemical, petroleum, light industry, medicine, fertilizer, synthetic fiber, food crystal, dye, environmental protection, and scientific research to measure the flow rate of single-phase non arterial (liquid or gas) fluids.

Corrosion resistant flow meters are mainly used for flow detection of corrosive liquids and gas media, such as strong acids (except hydrofluoric acid), strong bases, oxidants, strong oxidizing acids, organic solvents, and other corrosive gas or liquid media

feature

1. Low pressure loss

2. Reliable performance, convenient reading, and direct display

3. Simple structure, easy to install and use

4. Cheap price

Principle and Structure

The main measuring components of the flowmeter are a vertically installed lower small upper large conical glass tube and a float that can move up and down inside the tube.When the fluid flows from belowWhen flowing through a conical glass tube, a pressure difference is generated between the upper and lower parts of the float, and the float rises under this pressure difference. When the upward force equals the buoyancy and viscous lift acting on the float and the weight of the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate flowing through the flowmeter and the rising height of the float, that is, the flow area of the flowmeter. The position height of the float can be used as a measure of flow rate.

Note: ※ Corrosion resistant models with nominal diameter DN ≤ 10mm need to be customized and generally do not come with needle type regulating valves;

According to user requirements, we can produce corrosion-resistant flow meters with a higher level of precision.
