What should be paid attention to when installing a gas glass rotameter meter

Abstract: Information on what to pay attention to when installing a gas glass rotor flowmeter is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The main measuring element of the glass rotameter is a vertically installed lower and 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 sides of the float, and the float moves up under the action of this differential pressure. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details of what to pay attention to when installing gas glass rotor flowmeters. The main measuring element of the glass rotameter is a vertically installed lower and 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 top and bottom of the float, and the float rises under the action of this differential pressure. When the rising force, the buoyancy and the viscous lift on the float are equal to the gravity of the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow through the glass rotameter and the rising height of the float, that is, with the flow area of ​​the glass rotameter, and the position and height of the float can be used as a flow measurement. 1. Before installing the gas glass rotameter, check whether the technical parameters such as: measuring range, accuracy level, rated working pressure, temperature and other parameters meet the requirements of use. 2. Before installation, the top lining of the glass rotor flowmeter should be taken out for transportation protection. And check whether the cone tube is damaged, whether the float can move up and down freely, and then install it after confirming that it is normal. 3. Make the minimum division value of the glass rotameter at the bottom, and install it vertically on a pipeline without vibration. The angle between the center line of the rotameter and the vertical line should not exceed 5 degrees. Due to the heavy weight of the large-diameter flowmeter, in order to avoid the bending of the pipeline, measures such as reinforcement and support can be taken if necessary. 4. During installation, avoid the glass rotor flowmeter from being damaged by excessive external force, such as pressure and torque. If necessary, according to the different working conditions in use, install a filter upstream of the rotameter and plug the rotameter to prevent contamination by impurities. 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. 5. When the glass rotor flowmeter is used, the control valve on the upstream pipeline of the flowmeter should be slowly unscrewed, and then the flow rate should be adjusted with the regulating valve, so as to avoid the sudden rise of the float and damage to the cone tube.
