The Dynasonics® TFX-5000 Ultrasonic clamp-on flow meter is quickly and easily installed without cutting or tapping the pipe. This highly capable meter provides advanced features without breaking your budget.
The TFX-5000 transit time ultrasonic flow meter measures volumetric flow and heating/cooling energy rates in clean liquids as well as those with small amounts of suspended solids or aeration, such as surface water or raw sewage. TFX-5000 flow and energy meters clamp onto the outside of pipes and do not contact the internal liquid.
By clamping onto the outside of pipes, the meters have inherent advantages over other flow meter technologies, including:
• Reduced installation time and cost
• Non-invasive, non-contact measurement
• Continued operation during installation—no need to shut down the process
• No pressure head loss
• No moving parts to maintain or replace
• Large, bi-directional flow measuring range
• Data log up to 8 records
• Modbus® RTU or BACnet® MS/TP (BTL certification) over EIA-485; Modbus TCP/IP; BACnet/IP; EtherNet/IP; AquaCUE®/BEACON® connectivity
• Configuration and troubleshoot over USB or Bluetooth with SoloCUE app
• Reynolds, ultrasonic speed and temperature compensation
• Large, easy-to-read graphical display
• Rugged, aluminum enclosure for a long service life in harsh environments
Transit time flow meters measure the time difference between the travel time of an ultrasound wave going with the fluid flow and against the fluid flow. The time difference is used to calculate the velocity of the fluid traveling in a closed-pipe system. The transducers used in transit time measurements operate alternately as transmitters and receivers. Transit time measurements are bi-directional and are most effective for fluids that have low concentrations of suspended solids and are sonically conductive.
An ultrasonic meter equipped with heat flow capabilities measures the rate and quantity of heat delivered or removed from devices such as heat exchangers. By measuring the volumetric flow rate of the heat exchanger liquid, the temperature at the inlet pipe and the temperature at the outlet pipe, the energy usage can be calculated.

The TFX-5000 meter 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-5000 meter is available in two versions:
• A flow meter for water delivery, sewage, cooling water,
water-glycol mixtures, alcohols and chemicals
• A heating/cooling energy flow meter used in conjunction with dual clamp-on RTDs for temperature measurement—ideal for hydronic process and HVAC applications
