Introducing a small Kalman vortex flow meter with temperature compensation for liquids, featuring a liquid contact part made of "New PFA" ultrasonic flow meter for liquids!

We would like to introduce our Karman vortex flow meters / ultrasonic flow meters, the 'MODEL FML-300 SERIES/FML-500'. The compact Karman vortex flow meter for liquids, "MODEL FML-300 SERIES," measures fluid temperature with a built-in temperature sensor, reducing accuracy errors due to temperature changes through temperature compensation, and supports a wide flow range from 0.3 to 2.5 L/min up to 10 to 100 L/min. Additionally, the ultrasonic flow meter for liquids, "MODEL FML-500," features a straight structure without obstacles in the pipe, and is designed for fluids such as water and pure water. 【Standard Specifications (Partial)】 <MODEL FML-300 SERIES> ■ Target Fluids: Water, Pure Water, Chemical Solutions ■ Accuracy - FML-301/302/303/304: ±2% F.S. (25°C) - FML-305: ±3% F.S. (25°C) ■ Repeatability: ±0.5% F.S. *For more details, please refer to the PDF document or feel free to contact us.
