The TFX Ultra transit time meter measures clean liquids as well as those with small amounts of suspended solids or aeration such as
surface water or sewage.

• Bi-directional flow measurement system
• Totalizer options include forward, reverse and net total
• Modbus RTU or BACnet MSTP over RS485; Ethernet connections including BACnet/IP, EtherNet/IP, and
Modbus TCP/IP protocols
• Large, easy-to-read digital display
• Rugged, aluminum enclosure ensures a long service life in harsh environments
• Certified for hazardous area installation in North America and Europe

TFX Ultra ultrasonic flow and energy meters clamp onto the outside of pipes and do not contact the internal liquid. The technology has
inherent advantages over alternate devices including: low-cost installation, no pressure head loss, no moving parts to maintain or
replace, and a large, bi-directional measuring range that ensures reliable readings even at very low and high flow rates. The TFX Ultra is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.

The TFX Ultra is available in two versions:
• A flow meter
• An energy flow meter used in conjunction with dual clamp-on RTDs for temperature measurement—ideal for retrofit, hydronic process and HVAC applications
