Talking about the installation instructions of the glass rotor flowmeter

The cone of the glass rotor flowmeter is a transparent material of high borosilicate glass, which can measure the instantaneous flow of single-phase non-pulsating fluid (liquid or gas) in the pipeline. It is divided into two types: basic type and anti-corrosion type, which are widely used in chemical industry. Petroleum, light industry, medical, food and measurement testing, scientific research and other departments.
The glass rotor flowmeter has strong versatility, simple structure and convenient maintenance. Segmented metering, flexible measurement range, and measurable micro flow. The base is available in a variety of materials to measure corrosive media. The DN10 has a regulating valve below the diameter, which is convenient for manual adjustment on site. The installation of the glass rotor flowmeter is exquisite, and has the following requirements during installation and use:
1. The newly installed piping should be rinsed first.
2. Before using the glass rotor flowmeter, check the technical parameters such as: measuring range, accuracy level, rated working pressure, temperature and other parameters to meet the requirements.
3. Remove the top liner from the flowmeter for transport protection before installation. And check whether the cone is damaged, whether the float can move up and down freely, and it can be installed after normal.
4. Install vertically on a vibration-free pipe. The angle between the centerline of the rotameter and the plumb line should not exceed 5 degrees. Large-diameter flowmeters are heavy, in order to avoid bending of the pipeline, reinforcement measures can be taken when necessary.
5. When installing, avoid the rotor flowmeter being damaged by excessive external force. Open the valve slowly.
6. If necessary, install a filter upstream of the rotameter according to different working conditions in use to prevent impurities from entering the measuring tube, causing the float to become clogged.
7. If the fluid is unstable and has pulsating flow, a buffer can be installed to ensure good measurement of the rotameter to eliminate pulsating flow.
8. When using the glass rotor flowmeter, first slowly unscrew the control valve on the upstream pipe of the flowmeter, and then adjust the flow with the regulating valve to avoid sudden opening and causing the float to rise and damage the cone.
9. Finally, in order to obtain accurate measurement accuracy, it is recommended that the flow rate of the fluid to be measured should be more than 60% of the index flow of the rotor flow meter.
There is no complicated place in the mechanical watch. Since most of the glass rotor flowmeter body is made of glass material, it must be handled with care and transported carefully to ensure that the flowmeter is placed vertically and the inlet and outlet are connected, and the flowmeter can work normally. Therefore, in industrial production, the glass rotor flowmeter is a simple and convenient flow measuring instrument with low cost, high precision and wide use.
