TOFLO USF100A-K10EP Ultrasonic Flowmeter

The TOFLO USF100A-K10EP Ultrasonic Flowmeter delivers precise, contamination-free flow measurements for ultrapure water and aggressive chemicals in high-purity fluid-handling systems. It is part of the USF100A series and uses ultrasonic transit-time measurement, featuring a one-piece PFA body with no moving parts to support purity-critical operations in semiconductor manufacturing, chemical delivery, pharmaceutical processes, and ultrapure water distribution. The 1/2 in tube-end connection (K10EP) enables straightforward installation, while a measurement range of 50–2000 mL/min (pure water equivalent) and multiple analog and digital output options provide flexible integration with process control. Wetted parts are PFA construction to preserve chemical compatibility and contamination control across demanding sanitary environments. Typical applications include semiconductor wet-process equipment, chemical supply skids, ultrapure water systems, pharmaceutical manufacturing, and laboratory process equipment. The USF100A-K10EP can be paired with common replacements such as TOFLO USF500N, USF500S, and USF600S for retrofit or expansion projects.
