Vortex flow meter can be installed vertically, horizontally or at any angle. What’s more critical is that the fluid can fills the pipe completely and there is no any swirls or distortions in the upstream. Usually users will place control valves used to reduce the pipe size and keep the meter full, to be sure the meter will not influenced by the ball valve, between the upstream valve and the meter there must be have straight run. And, between the meter and the downstream valve there should be straight run equaling at least 5D(D here means the diameter of pipe) .
Detailed straight pipe line of vortex flow meter required:
|Valve in downstream|
|Valve in upstream|
|Pressure sensor:2~7D downstream of flowmeter
Temperature sensor: 1~2D downstream of pressure sensor
|Roots blower or piston blower or air compressor in upstream||
Roots blower or piston blower or air compressor or pump in upstream, could cause vibration of the fluid itself. To eliminate this vibration, please install a orifice plate or a upsized pipe at about 25D upstream the meter. The valve should be located downstream the flowmeter in this condition
|After a piston pump||
Please install a accumulator to reduce the vibration
|T type pipeline in upstream||
When upstream pipe line is T type the flowmeter and a valve downstream the meter is shut (see above picture), the fluid will all flow towards direct B, but the meter may still have reading for it may be detecting the pulsating pressure. Please move the valve to upstream of the meter to avoid this situition
|Gaskets should not get into the pipeline|
|Heat insulation: If the fluid is in high temperature, the heat insulation material should not cover the heat dissipation hole on flow meter|
|Pipe cleaning:If thepipeline need to be cleaned, please use a subtitied pipe to replace the flowmeter to invoid the meter being damaged by the cleaning fluid|
