TFX Ultra Transit Time Flow Meters

TFX Ultra transit time ultrasonic meters measure volumetric and energy flow of clean liquids, as well as those with small amounts of suspended solids or aeration, such as surface water or sewage. Ultrasonic waves are transmitted from outside the pipe into the liquid and propagate upstream and downstream.  The flow velocity is determined by the difference in the time of flight and is used to calculate the volumetric flow.

For energy metering, the temperature difference across heating and cooling equipment or zones is measured by dual RTD’s and is used with the volumetric flow to calculate the energy transfer.

Benefits

  • Reduced material cost by eliminating the need for in-line flanges, pipe fittings, strainers and filters
  • Reduced installation time
  • Reduced maintenance cost
  • Non-invasive measurement
  • No need to shut down the process for installation or maintenance due to clamp-on-sensor design

Features

  • Flow or energy metering
  • Bi-directional flow measurement system
  • No moving parts to wear or replace
  • Totalizer options include forward, reverse and net total
  • Modbus RTU or BACnet MSTP over EIA-485; Ethernet connections including BACnet/IP, EtherNet/IP, and Modbus TCP/IP protocols
  • Large, easy-to-read digital display
  • Rugged, aluminum enclosure provides a long service life in harsh environments
  • Certified for hazardous area installation in North America and Europe
  • UltraLink software utility enables in-field flow meter configuration, calibration and troubleshooting, via laptop PC
