The Dynasonics TFX Ultra Ultrasonic Flow Meter is a clamp-on ultrasonic flow and energy meter that provides accurate and repeatable measurements for full pipe liquid applications such as cooling lines, raw sewage flows, water distribution and processes where system shutdown is impossible. This versatile and accurate meter clamps on to the outside of pipes and does not contact the internal liquid which reduces installation and maintenance time and cost. 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 Dynasonics TFX Ultra is available in two versions: a stand-alone flow meter, and an energy flow meter used in conjunction with dual clamp-on RTDs. The energy flow meter measures energy usage in BTU, MBTU, MMBTU, Tons, kJ, kW, MW and is ideal for retrofit, hydronic and other HVAC applications.
The TFX Ultra has a wide, bi-directional measuring range that ensures reliable readings even at very low and high flow rates. For pipe/tubing sizes of 2" and lower, the TFX Ultra includes clamp-on transducers mounted and wired directly to the flow meter electronics enclosure. This design provides a convenient installation in areas where the user requires local indication. The TFX Ultra is also available with remote mounted transducers that permit separation of up to 990 feet (300 m). This design is utilized when pipes are located in areas that are not convenient for viewing, or on piping systems with severe vibration.
The TFX Ultra features a rugged, compact aluminum enclosure, easy-to-read digital display, bi-directional flow measurement, and a totalizer featuring forward, reverse and net total, and Modbus communications. The TFX Ultra offers an optional Ethernet connection as well as a USB programming port. With ease of operation a key component in designing the Series TFX Ultra, Windows based software utility UltraLink is available and compatible with all Dynasonics transit time flow meters to allow users to easily configure, calibrate, and troubleshoot with a notebook PC.

Here's how some of our customers used this product.
Retro Fit Building Efficiency Monitoring
The Background: Our customer is a bottling plant looking for a way to track the amount of energy used in their hydronic heating and cooling systems.
The Problem: The building and systems are old and the customers wants a non-invasive flow meter with the ability to take in temperature inputs that can then calculate energy usage, also known as BTU monitoring without a costly shut-down of the production line. This provides a way to monitor efficiency and determine if any of the loops are running below a threshold and need to be replaced.
The Solution: We recommended the Dynasonics TFX Ultra Ultrasonic Flow Meter, a clamp-on meter that measures both flow and energy. This solution allows the customer to maintain full operation of the system while they study it’s heating and cooling efficiency.
