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:

Standard  vortex flow meter straight pipe line requirements
Down sized  vortex flow meter straight pipe line requirements
Upsized  vortex flow meter straight piping line requirements
Curve pipeline  vortex flow meter straight piping line requirement
Dual-curve pipeline  vortex flow meter straight piping line requirements
Valve in downstream  vortex flow meter straight piping line requirements
Valve in upstream  valve in upstream straight piping line requirements

Pressure sensor:2~7D downstream of flowmeter

 

Temperature sensor: 1~2D downstream of pressure sensor

 temperature and pressure sensor downstream of flowmeter
Roots blower or piston blower or air compressor in upstream 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 After a piston pump straight piping line requirements

Please install a accumulator to reduce the vibration

T type pipeline in upstream T type pipeline requirements 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  vortex flowmeters straight piping line requirements
Heat insulation: If the fluid is in high temperature, the heat insulation material should not cover the heat dissipation hole on flow meter  vortex flow meter straight piping line requirement
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  vortex flowmeters straight piping line requirements

Requirements of steam vortex mass flow meter install:

In the application that temperature over +160°C/+320°F, we recommend adding insulation layer to protect the flow meters terminal board (terminal baord max temperature allowance is +80°C/+176°F) or to reduce heat loss. And, vortex meter meant to measure in the system requires to following directions.

Heat insulation layer or insulation jacket should not covered to the holder of the vortex meter.

The heat insulation layer can only extend to the position shown in below picture ①, ②, ③.

steam vortex meter install requirements

①, The position where the heat insulation layer ④ on the meter  holder extends to the maximum, heat insulation layer should not exceed this limit.

②, The position where the heat insulation layer④ on the temperature elbow lock nut extends to the maximum, heat insulation layer should not exceed this limit.

③, The position where the heat insulation layer ④ at the bend of the pressure elbow extends to the maximum. heat insulation layer should not exceed this limit.

④,  Heat insulation layer.
