Overview

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

Features

1. The pressure loss is small, and the pressure resistance: less than 1Mpa (10 kg), and the temperature resistance is below 100 degrees.

2. Reliable performance, convenient reading and direct display. Basic error: 2.5%, 4%.

3. Simple structure, easy to install and use

4. Cheap price

Principle and structure

The main measuring elements of the flowmeter are a vertically installed lower small and upper large conical glass tube and a float that can move up and down in the tube. When the fluid passes through the conical glass tube from below, a pressure difference is generated between the upper and lower floats, and the float rises under the action of this differential pressure. When this rising force = the buoyancy and viscosity of the float. When the lift is equal to the float's gravity, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the flow of fluid flowing through the flowmeter and the rising height of the float, that is, the flow area of the flowmeter, and the height of the float can be used as a flow measurement.
