Anti corrosion glass rotor flowmeterThe main measuring components are a vertically installed lower small upper large conical glass tube and a float that can move up and down inside. When the fluid passes through the conical 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 this pressure difference. When the upward force, buoyancy, and viscous lift acting on the float are equal to its gravity, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate flowing through the glass rotor flowmeter and the rising height of the float, that is, the flow area of the glass rotor flowmeter. The position height of the float can be used as a measure of flow rate. The product has a small volume, lightweight structure, beautiful appearance, easy maintenance, safety and reliability, and simple installation.
The correct installation steps for anti-corrosion glass rotor flowmeter are as follows:
1. Preparation before installation
Check if the flowmeter is intact, if the float can move freely, and if the glass tube is damaged.
Clean the pipeline to ensure no impurities remain and avoid damaging the flowmeter.
2. Installation position and direction
Vertical installation: The angle between the centerline of the flowmeter and the plumb line should be less than 2 ° to ensure that the fluid flows from bottom to top.
Environmental requirements: Avoid direct sunlight and highly corrosive environments, and the working temperature is usually 0-120 ℃.
3. Connection method
Flange connection: suitable for diameters above DN15, requiring alignment of pipeline flanges and uniform tightening of bolts.
Threaded connection: suitable for small diameters (such as DN15), requiring sealing tape or raw material tape to prevent leakage.
4. Pipeline and support
Upstream straight pipe section ≥ 5 times the pipe diameter, downstream ≥ 3 times the pipe diameter, to reduce fluid disturbance.
The pipeline needs to be independently supported to avoid stress transmission to the flow meter.
