The FlowBar-8 is a multi-channel mass flow instrument designed primarily for push mode respirometry applications.   Precision needle valves accurately set flow rates with a resolution of 1 milliliter per minute.  This instrument is available in four- or eight-channel configuration with standard flow ranges of 0-2 or 0-5 liters per minute.  It’s ideal for measuring the flow to multiple test chambers (accuracy <2% of reading) or to accurately divide a single input flow into multiple outputs.

The Flowbar-8 solves the problem of providing accurately measured mass flow rates to multiple locations, such as respirometer chambers in a multi-animal system.  Mass flow rates are automatically compensated for temperature and pressure, and yield STP flow rates without further calculation.  It can also eavesdrop on signals from our flow multiplexer, selecting the flow rate corresponding to the selected flow channel.  A serial flow rate output is also available.

The input gas flow can be from any source, such as a pump, gas cylinder or compressor.
