Hubbell Introduces Vortex Flow Meter Option for Tankless Heaters

Hubbell is excited to announce the option of vortex flow meters for our tankless product line. Vortex flowmeters lack moving parts which can lead to mechanical wear and premature failure. This new option expands the application range of our Tankless Series. Most notably, continuous use installations, such as recirculation loops.

“With this option, customers will enjoy increased performance and reliability, which reduces lifetime operating costs” says Kyle MacPherson, one of Hubbell’s Electrical Engineers and lead engineer on the vortex upgrade project.

The vortex flowmeter is offered on some of Hubbell’s Tankless Series models, including the popular HX and TXA. While our tankless units come standard with a turbine flow meter, our vortex meter upgrade functions more efficiently. It works based on a natural phenomenon that occurs when a fluid flows past a bluff object. As the liquid moves around the object, vortices (or eddies) are alternately shed downstream, a process known as vortex shedding. The frequency at which these vortices are generated is directly proportional to the velocity of the fluid passing through the meter.

Vortex flow meters are particularly well suited for applications where the use of moving parts is undesirable or impractical. Since they lack moving components, vortex flow meters exhibit low sensitivity to changes in process conditions and experience relatively low wear compared to other types of flow meters.

The minimum flow rate is 2GPM and the maximum is 40GPM.

Turbine Flow Meter Advantages

  • Larger flow range (0.5-40 GPM)
  • More accurate
  • Better for short term on demand heaters
  • Available in high pressure HX option

Vortex Flow Meter Advantages

  • Flow range (2-40 GPM)
  • Less maintenance
  • Longer durability
  • Lower cost
  • Better for recirculation systems

If you are considering a Hubbell Tankless model for a continuous application, ask your Hubbell salesperson if a vortex flow meter would work better. For reference, the vortex flow meter coded option is C63 for the following tankless units: TXA, HX, MTXA and MHX.
