Compressed Air Tri-clamp Vortex Flow Meter introduction


 

Classified as a vortex flow meter, this device utilises a law that was theoretically proven by Theodore

von Karman in 1912. When there is a column-shaped obstruction (vortex shedder) in flowing fluid,

it will generate alternating vortices downstream. The flow velocity of the fluid and the vortex generation

frequency are proportional to each other. Therefore, detecting the number or pulse of vortices makes it

possible to measure flow. The main method of detection involves sensing the vortex vibration with a piezo

element. However, a more robust method utilises ultrasonic waves to detect the vortex vibration.

 Compressed Air Tri-clamp Vortex Flow Meter

Calibration is the most important parts of manufacturing the high accuracy flowmeter,As the principle is the same,the material and the structure design of the flowmeter is not much different.High accuracy flowmeters depends on the high accuracy calibration equipment.

 

Compressed Air Tri-clamp Vortex Flow Meter advantages

 

  • We use the reference flowmeter method to confirm the fflowmeter condition
  • We use the label to remind customer where to connect the power and voltage in case the unmatched voltage damage the flowmeter.
  • The big screen LCD display the forward gross volume,flow volume and unit clearly.
