On-site piping installation requirements for vortex flowmeters

Abstract: The information on the installation requirements of the vortex flowmeter on-site is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. 1. The pipeline where the vortex flowmeter is installed should be filled with the measured medium, and the flow direction mark of the vortex flowmeter should be consistent with the flow direction of the fluid in the pipeline. 2. It should be avoided to install on the pipeline with strong mechanical vibration. 3. When the measured medium contains a lot of impurities, it should flow in the vortex. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on the field pipeline installation requirements of the vortex flowmeter meter. 1. The pipeline where the vortex flowmeter is installed should be filled with the measured medium, and the flow direction mark of the vortex flowmeter should be consistent with the flow direction of the fluid in the pipeline. 2. It should be avoided to install on the pipeline with strong mechanical vibration. 3. When the measured medium contains a lot of impurities, a filter should be installed beyond the required length of the upstream straight pipe section of the vortex flowmeter. 4. The vortex flowmeter should be avoided to be installed in places with strong electromagnetic field interference, small space and inconvenient maintenance. 5. Requirements for the straight pipe section of the vortex flowmeter a. The flowmeter should be installed on a horizontal, vertical, inclined (liquid flow from bottom to top) pipeline with the same diameter. The upstream and downstream of the sensor should be equipped with straight pipe sections of a certain length, and the length should meet the requirements of 15~20D for the front straight pipe section and 5~1OD for the rear straight pipe section. b. If there is a reducer pipe upstream of the installation point of the flowmeter, the upstream of the flowmeter should have an equal-diameter straight pipe section of not less than 15D (D is the diameter of the pipe), and the downstream should have an equal-diameter straight pipe section of no less than 5D. c. If there is a gradually expanding pipe upstream of the installation point of the flowmeter, the upstream of the flowmeter should have an equal-diameter straight pipe section of not less than 25D (D is the diameter of the pipe), and the downstream should have an equal-diameter straight pipe section of not less than 5D. d. If the flowmeter is installed Point upstream has 90°For elbows or downlink joints, the upstream of the flow meter should have an equal diameter straight pipe section of not less than 20D, and the downstream should have an equal diameter straight pipe section of not less than 5D. e. If there are two 90s on the same plane upstream of the installation point of the flowmeter°Elbow, the upstream of the flow meter should have an equal diameter straight pipe section not less than 25D, and the downstream should have an equal diameter straight pipe section not less than 5D. f. If there are two 90s on different planes upstream of the installation point of the flowmeter°Elbow, the upstream of the flow meter should have an equal diameter straight pipe section not less than 40D, and the downstream should have an equal diameter straight pipe section not less than 5D. g. The flow regulating valve or pressure regulating valve should be installed as far as 5D downstream of the flowmeter. If it must be installed upstream of the flowmeter, when the valve can meet the full opening requirements, there should be a straight pipe section of equal diameter not less than 25D upstream of the flowmeter. , the downstream should have an equal diameter straight pipe section of not less than 5D. When the valve can only meet the half-opening requirements, the upstream of the flowmeter should have an equal diameter straight pipe section of no less than 50D, and the downstream should have an equal diameter straight pipe section of no less than 5D. h. If there is a piston or plunger pump, piston or Roots fan, compressor upstream of the flowmeter, there should be an equal diameter straight pipe section of not less than 50D upstream of the flowmeter, and an equal diameter straight pipe section of not less than 5D downstream. Special attention: If a valve is installed near the upstream of the installation point of the vortex flowmeter, and the valve is opened and closed continuously, it will greatly affect the service life of the flowmeter, and it is very easy to cause permanent damage to the flowmeter. Try to avoid installing the flowmeter on a very long overhead pipeline. After a long time, the sagging of the flowmeter will easily cause the leakage of the seal of the flowmeter on the flange. If it is installed, it must be installed upstream and downstream of the flowmeter. Pipe fastening devices are installed at the respective locations. The above is the whole content of this article.
