Installation steps of glass rotor flowmeter in use1. First, check whether its technical parameters such as measurement range, accuracy level, rated working pressure, temperature and other parameters meet the requirements of use.2. When preparing to install, take out the top lining material of the flowmeter which plays a role of transportation protection. And check whether the cone tube is damaged, whether the float can move up and down freely, and you can install it after confirming that it is normal.3. The newly installed pipeline should be flushed clean before installation of the glass rotor flowmeter.4. Make the minimum graduation value of the rotameter at the bottom and install it vertically on a vibration-free pipeline. The angle between the centerline of the rotameter and the plumb line should not exceed 5 degrees.5. Due to the heavy weight of large-caliber flowmeters, in order to avoid pipe bending, measures such as reinforcement and support can be taken when necessary. It is also necessary to avoid excessive tension, compression, torsion and other forces on the rotameter during installation. So as not to produce excessive external force and damage the cone tube.6. According to different working conditions in use, if necessary, a filter should be installed upstream of the rotameter to prevent impurities from contaminating and blocking the rotameter. If the fluid is unstable and has pulsating flow, in order to ensure good measurement of the rotameter, a buffer can be installed to eliminate the pulsating flow.7. After the rotameter is installed and ready to be put into use, first slowly unscrew the control valve on the upstream pipe of the flowmeter, and then adjust the flow with the regulating valve, so as not to suddenly open and cause the float to rise rapidly and damage the cone tube. In order to ensure the measurement accuracy of the rotameter in use, it is recommended that the common flow rate of the fluid to be measured should be more than 60% of the upper limit of the rotameter indexing flow.
