TSI 5300 Series Mass Flow Meter


The 5300 Series high flow thermal mass flow meters provide the ability to measure high flows with an ultra low pressure drop, measuring up to 300 l/min while minimizing flow back pressures and their impact on your system. These flow meters also have a lightweight, compact form factor when compared to other instruments that measure at similar flow rates. The 5300 Series is designed as a general purpose flow meter and is optimized for applications within the respiratory equipment market.
