Trusted flow measurement

Reliable measurement of flow plays an important role in maximising HVAC system efficiency and conserving energy. Inline flow sensors from Belimo utilise ultrasonic transit-time technology to provide accurate and repeatable water-flow measurement. Their compact size and insensitivity to dirt make them ideal for use with HVAC chilled water, hot water and water / glycol solutions at temperatures ranging from –20 to 120 °C.

  • Certainty that the measured flow is correct.
  • Only one flow sensor required for glycol concentrations up to 60%.
  • Maintenance-free design ensures reliable operation and long service life.
