The Conical / Annular: Digivent

Product Summary

The Digivent is a differential pressure flow meter that employs the same physical principles as the differential pressure meters considered in ISO 5167-4:2003 standard. Developed based on Annular Orifice and Venturi Tube meters, Digivent is an outstanding choice for measuring industrial fluids, including wet and contaminated gases. It avoids clogging of pressure taps and does not require long straight pipe lengths, thanks to its annular orifice design similar to the Annular Orifice.

Main Features:

  • Reduced Straight Pipe Length Requirement: Reduces the demand for straight pipe lengths in the installation.
  • Decreased Permanent Pressure Loss: Minimizes flow resistance.
  • Enhanced Reliability in Differential Pressure Measurement: Offers 4 internal measurement points for greater accuracy.
  • Low Probability of Pressure Tap Clogging: Suitable for measurement in environments with solid particles.
  • Wide Range of Beta Values (β): Can be calculated with Beta values from 0.25 to 0.75.

Applications:

  • Water and Sanitation Treatment
  • Oil and Gas Industry
  • Oil Refineries
  • Chemical and Pharmaceutical Industry
  • Food and Beverage Industry
  • Mining and Energy
  • Pulp and Paper Industry
  • Steel Industry

Operation:

The Digivent is a conical/bore deflector flow meter or annular bore deflector, based on the basic theories that underlie differential pressure flow meters. It is designed with advanced differential pressure technology and is ideal for applications with limited operating space. Due to its aerodynamic profile, Digivent is the right choice for applications involving wet or particulate-laden fluids.
