1. Requirements for straight pipe section before and after installation of various flow meters
Technical requirements for installation of vortex flowmeter
1. The length of the front straight pipe section shall not be less than 10D; 2. The length of the rear straight pipe section shall not be less than 5D; 3. Use gas welding to open a circular hole slightly smaller than φ 100mm on the pipeline, and remove burrs around the circular hole to ensure smooth rotation of the measuring head; 4. Weld the flange provided by the manufacturer at the circular hole of the pipeline, with the flange axis perpendicular to the pipeline axis; 5. Install the ball valve and sensor onto the welded flange; 6. Adjust the screw to ensure that the insertion depth meets the requirements and that the fluid flow direction is consistent with the direction indicated by the arrow; 7. Tighten the screws on the cover evenly; 8. The cable should be bent into a U-shape at the electrical interface to prevent water from entering the amplifier housing along the cable; There should be sufficient space around the instrument installation point for easy installation, wiring, and regular maintenance. Technical requirements for installation of full tube vortex flowmeter: 1. The length of the front straight pipe section is 10D; 2. The length of the rear straight pipe section is 5D; 3. Weld the flange provided by the manufacturer on the pipeline to ensure that the flange axis is perpendicular to the pipeline axis; 4. Install the sensor on the welded flange; 5. Ensure that the fluid flow direction is consistent with the arrow on the directional marker. Technical requirements for installation of electromagnetic flowmeter
1. The length of the front
1. The length of the front straight pipe section should not be less than 8D; 2. The length of the rear straight pipe section should not be less than 5D; 3. When welding the flange used to clamp the throttling element to the process pipeline, the flange sealing surface should be perpendicular to the pipeline axis, and the flange axis should coincide with the pipeline axis. There should be no protruding weld meat at the flange sealing surface pipe mouth welding point, and it should be polished flat; 4. The throttling device and pressure pipeline are made of stainless steel and must be welded using argon arc welding; 5. The gasket should be coaxial with the pipeline and not allowed to be offset; 6. The pressure tap of the throttling device should be aligned with the centerline of the process pipeline; 7. The installation direction of the ring chamber should be such that the side marked with a "+" on the ring chamber is installed upstream of the throttling element; 8. The throttling device should be carefully cleaned before installation to ensure that the throttling element is not damaged, and the rust proof grease should be remo
