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 990ft (300m). 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.
