Vortex Flowmeter

Vortex flowmeter: The correct choice of installation point and correct installation of the flowmeter are both very important links. If the installation process is incorrect, it will affect the measurement accuracy, and the more serious will affect the service life of the flowmeter, or even damage the flowmeter. Vortex flowmeter installation requirements for straight pipe sections are very important. Its detailed requirements are as follows: Flow meter to the upstream and downstream straight pipe section at the installation point a vortex flow meter: Correct selection of the installation point and correct installation of the flow meter are very important links. If the installation process is wrong, the measurement accuracy will be affected. The more serious ones will affect the service life of the flowmeter and even damage the flowmeter. Vortex flowmeter installation requirements for straight pipe sections are very important. Its detailed requirements are as follows: 　The 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 not less than 15D (D is the pipe diameter) upstream of the flowmeter, and an equal-diameter straight pipe section not less than 5D downstream. If there is a diverging pipe upstream of the flowmeter installation point, there should be an equal-diameter straight pipe section not less than 18D (D is the pipe diameter) upstream of the flowmeter, and an equal-diameter straight pipe section not less than 5D downstream. If there is 90% upstream of the flowmeter installation point ° For elbows or downstream joints, there should be equal-diameter straight pipe sections not less than 20D upstream of the flowmeter, and equal-diameter straight pipe sections not less than 5D downstream.　If the upstream of the flow meter installation point has a 90° elbow on the same plane, the upstream of the flow meter should have an equal-diameter straight pipe section of no less than 25D, and the downstream should have an equal-diameter straight pipe section of no less than 5D. The flow regulating valve or pressure regulating valve should be installed as far as possible 5D downstream of the flowmeter. If it must be installed upstream of the flowmeter, there should be equal-diameter straight pipe sections not less than 25D upstream of the flowmeter, and equal-diameter straight pipe sections no less than 5D downstream. .　If there are piston or plunger pumps, piston or Roots fans, compressors upstream of the flowmeter, there should be equal-diameter straight pipe sections not less than 25D upstream of the flowmeter, and equal-diameter straight pipe sections no less than 5D downstream.
