- 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 5-100, 50-500, or 400-2000 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.
