1. Requirements for the installation of steam pipe flow meters The core requirements for the installation of steam pipe flow meters can be summarized into nine aspects: grounding protection, position selection, direction angle, etc. Strictly following these requirements can ensure the accuracy of measurement and the stability of equipment. 1. Installation and Grounding - Strictly follow the instructions for installation, and measure the grounding resistance value to be ≤ 10 Ω after completion. -Equipotential bonding wires should use multi strand copper bundle wires with an area of ≥ 16mm ², and instrument grounding wires should use wires of the same material with an area of ≥ 6mm ²

. 2. Installation location selection - avoid strong vibration, high temperature/radiation heat sources, and corrosive environments. If unavoidable, shock-absorbing short joints or protective covers should be installed. -Outdoor installation should be equipped with sunshade and rainproof measures, and kept away from strong magnetic field equipment such as ferromagnetic objects, large motors, transformers, etc. -Priority should be given to selecting a location that is convenient for maintenance operations. Installation direction and angle - horizontal, vertical, and inclined installation are allowed. When measuring liquids, ensure that the fluid flows from low to high; -Unrestricted gas flow direction; -When measuring steam or high-temperature gases, the support column of the meter body should form a 45 ° angle with the vertical direction. 4. Requirements for straight pipe sections - upstream retention of equal diameter straight pipe sections of ≥ 10D (recommended 20D), downstream ≥ 5D. - It must be installed horizontally in the pipeli

ne, with the axis concentric with the pipeline and an installation inclination of ≤ 5 °. 5. Piping and welding requirements - The inner diameter of the upstream and downstream pipelines should be strictly consistent with the flow meter. -Flange welding requires the installation of a flow meter after the independent completion of pipeline welding to avoid damage to the instrument during welding

6. Bypass detection pipe and valve settings - Install shut-off valves before and after the flow meter and set up bypass pipelines to ensure that the grinding maintenance does not stop. -The flow control valve is placed downstream of the flow meter, and the upstream valve is kept fully open during use. 7. External environmental control - indoor installation is preferred, and outdoor measures such as sun protection, rain protection, and lightning protection should be taken. -The ambient temperature should be controlled between -20 ℃~+60 ℃, humidity should be less than 85%, and dry ventilation should be maintained. 8. Maintenance points in the later stage - After the pipeline is first filled with steam or high-temperature medium, the flange bolts should be re tightened and the pipeline insulation should be implemented. -The valve and sealing gasket in front of the pressure transmitter should be intact and leak free, and the installation position should be located 4 times the diameter downstream of the flowmeter.
