Technical requirements for installation specifications of several flow meters

Abstract: The technical requirements information of several flow meter installation specifications is provided by the excellent flow meter and flow meter production and quotation manufacturers. Installation technical requirements of plug-in vortex flowmeter: 1. The length of the front straight pipe section is not less than 10D; 2. The length of the rear straight pipe section is not less than 5D; Clean the surrounding burrs to ensure the probe. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the technical requirements for the installation of several flowmeters. Installation technical requirements of plug-in vortex flowmeter: 1. The length of the front straight pipe section is not less than 10D; 2. The length of the rear straight pipe section is not less than 5D; Clean the surrounding burrs to ensure smooth rotation of the probe; 4. Weld the flange provided by the manufacturer at the round hole of the pipe, and the axis of the flange is required to be perpendicular to the axis of the pipe; 5. Install the ball valve and sensor on the welded flange ;6. Adjust the lead screw so that the insertion depth meets the requirements, and the fluid flow must be consistent with the indication arrow on the direction mark; 7. Tighten the screws on the gland evenly; 8. The electrical interface should be bent into a U-shape, Avoid water entering the amplifier housing along the cable; 9. There should be a certain space around the installation point of the instrument for installation wiring and regular maintenance; technical requirements for the installation of the full-tube vortex flowmeter: 1. The length of the front straight pipe section is 10D; 2 , The length of the straight pipe section is 5D; 3. Weld the flange provided by the manufacturer on the pipeline, and the axis of the flange is required to be perpendicular to the axis of the pipeline; 4. The sensor is installed on the welded flange; 5. The fluid flow direction must be marked with the direction The indicating arrows of the two parts should be consistent; technical requirements for electromagnetic flowmeter installation: 1. The front straight pipe section is not less than 30D (when mixing liquid); 2. The rear straight pipe section is not less than 5D; 3. The vertical pipe is preferred; use a torque wrench to tighten the nut , the maximum torque of caliber DN50 is 55N﹒ m, the maximum moment of caliber DN40 is 43N﹒ m; 5. In order to facilitate installation, maintenance, and maintenance, there should be ample installation space around the flowmeter;) Technical requirements for the installation of throttle orifice flowmeter: 1. The front straight pipe section is not less than 8D; 2. The rear straight pipe section is not less than 5D; 3. When welding the flange for clamping the throttling piece to the process pipeline, the flange sealing surface and the pipeline axis should be vertical, and the flange axis and the pipeline axis should be coincident. Welding meat should be polished flat. Using butt welding flange, the inner diameter of the flange must be equal to the inner diameter of the process pipe, the axis of the flange and the axis of the process pipe are coincident, the nozzles are aligned, and no welding residue is allowed in the weld; 4. Throttle device and pressure piping The material is stainless steel and must be welded by argon arc; 5. The gasket should be coaxial with the pipeline, and no offset is allowed; 6. The orientation of the pressure port of the throttling device is flush with the centerline of the process pipeline; 7. The installation direction of the ring chamber , the ring chamber has“+”The side of the mark should be installed on the upstream side of the throttling element; 8. The throttling device should be carefully cleaned before installation, and the throttling element should not be damaged, and the anti-rust grease should be removed; 9. The throttling device should be cleaned in the pipeline 10. The installation of the condensing tank should be at the same height and the same horizontal position; 11. The display part of the instrument should face the direction that is convenient for the observer; technical requirements for the installation of the target flow switch: 1. The flow direction of the medium is the same as that on the outer casing. The direction of the arrows is the same; 2. The target of the controller is perpendicular to the flow direction of the medium; 3. There must be a direct guide with a length of 10 times the diameter of the pipe in front of the controller; Jinhu Liantai Instrument: Ms. Song: The above is the entire content of this article, welcome to inquire My manufacturer's flowmeter selection, quotation and so on.
