TFX-500w Ultrasonic Clamp-on Flowmeter

The TFX-500w transit time ultrasonic flow meter measures the volumetric flow of clean water in pipes 10 in. or smaller. By clamping on the outside of the pipe, the ultrasonic meter is installed without cutting or tapping the pipe.


  • Clamp-on, non-invasive flow meter
  • Bidirectional flow measurement system
  • Measures flow rate, total and velocity of water flow
  • Set up the meter through keypad interface or with SoloCUE® Flow Device Manager software
  • Compact enclosure uses large, easy-to-read graphical display
  • Modbus RTU or BACnet MS/TP over RS485 and
  • BEACON®/AquaCUE® connectivity



• Reduces installation costs, especially retrofits
◊ Installs without cutting into the pipe
◊ Eliminates flanges and pipe fittings
◊ Eliminates draining and air purging
• Eliminates ingress or leak points in pipes
• No moving parts to maintain
• No pressure head loss


The TFX-500w meter is well suited for building automation, water distribution and wastewater collection in new and retrofit applications. In addition to having lower installation costs than an inline flow meter, the TFX-500w meter can be installed while the system continues to operate without interruption.

The TFX-500w meter is suitable for:
• Potable water
• Reclaimed water
• Chiller water
• Boiler feed water
• Make-up water
• Condenser water
• Condensate
