  • Portable mass flow generator housed in a weather-tight, impact resistant carry case
  • Employs PID modulated rotary pumps for quiet and efficient operation
  • User can calibrate and change multiple settings on the instrument, with flow set-point and actual flow displayed during operation
  • Wide ranges of 5-90, 50-450, and 400-1650 SLPM
  • Ideal for medium to large mammals, from goats up to elephants or whales
  • Long-life pump with very low noise


The Sable field version FlowKit is a integrated low-noise pump and mass flow generator housed in a portable, virtually indestructible carry case. It’s designed to accurately and quietly deliver large flow rates for applications such as large animal respirometry, or air circulation in small, controlled environments.   Available in 3 different models – the FK-100-1, FK-500-1 and FK-2K-1 – for flow ranges of 5-90, 50-450, or 400-1650 liters per minute.

The FlowKit relies on modulating a powerful but quiet pump in order to create the set mass flow rate. Ultra-efficient PID (proportional integral derivative) control is used for quick response to setpoint changes and minimal variation from the setpoint. As a result, the pump works only as hard as it has to, greatly reducing pump wear, power consumption and noise.

A sub-sampling pump simplifies plumbing to a respirometry system, and features both analog and serial outputs for easy connection to a data acquisition system. The FlowKit requires no temperature or barometric pressure correction because it generates mass or molar flow rates already corrected to STP. It also features a user-configurable alarm to alert users locally and remotely if a fault develops.
