The KOFLOC FML-500 is an ultrasonic liquid flowmeter that combines high measurement accuracy with a completely unobstructed flow path. Thanks to the ultrasonic transit-time principle, the FML-500 measures liquids without moving parts, pressure loss or risk of contamination. This makes it ideal for applications in water quality systems, chemical processes, laboratories, semiconductor installations and other environments where absolute reliability and low-maintenance operation are essential. The meter offers stable performance, a robust construction with PFA wetted parts and accurate flow measurements up to 5 litres per minute.
Key features
- Suitable for water and ultrapure water
- Measuring range up to 5 L/min
- Very high accuracy: ±30 mL/min to ±1.5 percent of full scale
- No moving parts, low maintenance
- New PFA wetted parts for maximum compatibility
- IP64-behuizing and compact design
- Display of instantaneous and integrated flow (with display)
- Ultrasonic time-difference measuring method for stable and reproducible results
The construction without obstructions in the measuring tube reduces blockages and makes the meter suitable for critical applications in semiconductor, ultrapure water treatment, chemical processes and R&D, among others.

FAQ: frequently asked questions
Is the FML-500 suitable for liquids other than water?
Yes, but only on request. The standard configuration is optimised for water and ultrapure water without entrained air.
Can the meter be mounted horizontally?
Yes, horizontal, vertical and inclined mounting is permitted.
Is air in the liquid a problem?
Yes, air bubbles affect the ultrasonic measurement. A bubble trap or degasser is recommended.
How is the flow measured?
Via an ultrasonic propagation time difference method that is very stable at different temperatures.
Is er onderhoud nodig?
The meter contains no moving parts and requires virtually no maintenance.
