Simple Installation. Cost-Effective Solution.

Because of its clamp-on design and impressive accuracy, the Dynasonics TFX-500w flow meter is a cost-effective option for measuring water flow in a variety of applications.

  • Non-Invasive/Non-Contact. These meters easily attach to a pipe’s exterior and are secured in place without ever penetrating the pipe or coming in contact with the internal liquid. This feature is especially beneficial in settings where the liquid should not be exposed, such as caustic liquids, raw sewage or ultrapure water. 
  • Streamlined Installation. Can be installed without cutting into the pipe, eliminating the need for flanges, pipe fittings, draining and air purging.
  • Application Flexibility. Is suitable for building automation, water distribution and wastewater collection in new and retrofit applications.
