  • Improved bubble resistance and flow measurement
    • The conventional ultrasonic flowmeters used to have difficulties in measuring fluids containing bubbles because the bubbles disturb the propagation of ultrasound waves.
    • The FCA6000 series uses our unique, proven signal processing technology, which makes it possible to measure the flow even when the bubbles contain.
    • Furthermore, by detecting and removing abnormal outputs based on our extensive field experience, bubble resistance has been greatly improved, as well as measurement stability of the flowmeter.
  • Enhanced safety and freedom in layout
    • The flow detector and the control valve in the process fluid part are separated from the measurement and control part, ensuring enhanced protection against liquid leakage as well as greater freedom in layout.
  • Support for a wide flow range
    • The FCA6000 series covers a wide range of flow rate, from a minimum of 2.5 to 25 mL/min up to 1 to 10 L/min.
  • Low power consumption
    • The FCA6000 series consumes less current than existing converters.
  • CE marking
    • Complies with EU EMC, RoHS2, and low voltage requirements
      (EMC standards: EN61326-1: 2013, EN61326-2-3: 2013)
  • High corrosion resistance
    • The UCUF series uses highly corrosion resistant PFA and PTFE for the wetted parts and can be used to handle chemical liquids in the semiconductor and other industries.
