Kofloc Ultrasonic Flow Meter for Liquid Model FML-500

The Kofloc FML-300 SERIES represents the pinnacle of clean flow measurement.

Description

The Kofloc FML-300 SERIES represents the pinnacle of clean flow measurement. While vortex or turbine meters require a bluff body or rotor in the fluid stream, the FML-500 uses ultrasonic transducers mounted outside the flow path to measure fluid velocity. This “clean” architecture ensures that the meter never introduces contaminants into the liquid—a critical requirement for the semiconductor and pharmaceutical industries.

The Kofloc FML-300 Series is a high-precision Karman Vortex flow meter designed specifically for liquids like ultrapure water and harsh chemicals. Its standout feature is the integrated temperature sensor, which allows the unit to perform real-time temperature correction, significantly reducing accuracy errors caused by fluid temperature fluctuations.
