How to select your liquid flow meter?

For (ultra) low liquid flows, tiny disturbances in the process or ambient conditions can have a huge impact on flow stability. Deciding which liquid flow meter is best for the low-flow application largely depends on accuracy and stability requirements. However, ambient or media conditions which are difficult to control can also play an important role in choosing the best instruments. 

Bronkhorst has thermal-based, Coriolis-based and ultrasonic-based liquid flow meters in the product portfolio, both suitable for low liquid flow measurement.

Tips ‘n’ tricks for selecting the best liquid flow meter

  • Select an instrument suitable for the process and ambient conditions.

  • Make sure to provide a stable inlet pressure to the liquid system.

  • If you use a pressure vessel, make sure to minimise the containment or dissolution of gas in the liquid.

  • Minimise the internal volume between the liquid flow meter and the process.
