CBRO vortex flowmeter is used for measuring the flow velocity of gases or liquids in pipelines flowing full. The measuring principle is based on the development of a Karman vortex shedding street in the wake of a body built into the pipeline. The periodic shedding of eddies occurs first from one side and then from the other side of a bluff body (vortex-shedding body) installed perpendicular to the pipe axis. Vortex shedding generates a so called "Karman vortex street" with alternating pressure conditions whose frequency is proportional to the flow velocity.

 

Features:

  • Lattice LCD display
  • Easy operation
  • Configure with temperature/pressure senor. For temperature sensors, Pt100 or Pt1000; For pressure sensor, gauge pressure sensor or absolute pressure sensor
  • Multiple Outputs can be optional: Two-Wire 4-20mA, Three-Wire pulse and Three-Wire equivalent output
  • Excellent nonlinearity correction function, greatly improve the appearance of linearity
  • Spectral analysis, improve the ability of anti-interference and vibration resistance
  • A variety of measuring medium: vapor, liquid, gas and natural gas, etc.
  • Low power consumption, a dry cell can maintain at least 3 years
  • Automatic switching ability of the working modes: Battery supply, Two-Wire and Three-Wire
  • Self-checking function: the rich self-checking information make easy maintenance and debugging
  • Independent password setup, the parameters setup, total flow reset and calibration can be set with different- level passwords, it is convenient for management
  • Three-Wire system supports RS485 communication The display unit can be selected and user-defined
