Intelligent vortex flowmeterThe installation requirements for straight pipe sections are very important.
Intelligent vortex flowmeterThe detailed requirements are as follows:
The intelligent vortex flowmeter has certain requirements for the upstream and downstream straight pipe sections at the installation point, otherwise it will affect the measurement accuracy.
If there is a tapered pipe upstream of the installation point of the flowmeter, there should be an equal diameter straight pipe section of not less than 15D (D is the diameter of the pipeline) upstream of the flowmeter, and an equal diameter straight pipe section of not less than 5D downstream.
If there is a gradually expanding pipe upstream of the installation point of the flowmeter, there should be an equal diameter straight pipe section of not less than 18D (D is the diameter of the pipeline) upstream of the flowmeter, and an equal diameter straight pipe section of not less than 5D downstream
If there is a 90 ° elbow or downward joint upstream of the installation point of the flowmeter, there should be an equal diameter straight pipe section of not less than 20D upstream and an equal diameter straight pipe section of not less than 5D downstream of the flowmeter.
If there is a 90 ° elbow on the same plane upstream of the flowmeter installation point, there should be an equal diameter straight pipe section of not less than 25D upstream of the flowmeter and an equal diameter straight pipe section of not less than 5D downstream.
The flow regulating valve or pressure regulating valve should be installed as far downstream as 5D of the flowmeter. If it must be installed upstream of the flowmeter, there should be an equal diameter straight pipe section of not less than 25D upstream and an equal diameter straight pipe section of not less than 5D downstream.
Intelligent vortex flowmeterIf there are piston or plunger pumps, piston or Roots fans, compressors upstream, the flow meter should have an equal diameter straight pipe section of not less than 25D upstream, and an equal diameter straight pipe section of not less than 5D downstream.
