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 determining 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, if necessary, reinforcement measures can be taken.
5. When installing, avoid the rotor flowmeter being damaged by excessive external force, and 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 open 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 sharply 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 flowmeter.
