digitalYEWFLO Reduced Bore Type Vortex Flowmeter
The new SSP amplifier used in the digital YEWFLO series is backwards compatible with earlier YEWFLO vortex flowmeters, enabling them to be retrofitted with the best vortex measurement technology available today.

The digitalYEWFLO Reduced Bore Type Vortex Flowmeter features a cast stainless steel body and a concentric reducer and expander that enable stable flowrate measurements in low-flow conditions.
This model reduces installation cost and expands the range of applications available to customers.

  • The optimal solution
  •  
    - No longer is it necessary to change the orifice plate to adjust for changes in the flow rate.
    - Totalization and self-diagnostic functions are available for enhanced flowrate management.


  •  Easy installation
  •  
      <Conventional configuration>
      - Installation is difficult, involving many different nuts, bolts, and gaskets.
      - Customer must provide reducers and extension tubes.
      - There are six connection points, each of which is a potential leak point.
     
     
      <The reduced bore digitalYEWFLO solution>
      - Expanded low flow measurement range
      - Easy to install
      - Requires no additional parts
      - There are only two connection points -- meaning there are fewer locations where leaks can occur.
      - The same face-to-face dimensions eases the task of installing other sizes or types of digitalYEWFLO flowmeters.
     
     
     


    While formerly two different types of orifice plates had to be changed to adapt to fluctuations in the line flow rate, this is no longer necessary with the digitalYEWFLO reduced bore type.
    In lines that require annual or long-term flow maintenance, the digital YEWFLO eliminates the need to interrupt the flow to perform this work.
    Yokogawa vortex flowmeters are well suited to high temperature and high pressure applications, and the quality of flow management can be improved even further through the use of anti-vibrating efficiency and self diagnostic functions that rely on the digitalYEWFLO's SSP system.
