Description The Digital 300 Series of thermal mass flow meters and controllers from Teledyne are designed to accurately measure mass flow without corrections or compensations for gas pressure and temperature. They are accurate to better than ±(0.5% of reading + 0.2% of full scale) for full scale flow rates from 0-5 sccm to 0-10,000 slm. The Digital 300 Series uses a thermal-based mass flow sensor. This sensor is designed to provide exceptional linear response to changing flow rates. In addition, the electronics associated with each sensor are precisely tuned to give fast response times. The flow...

www.teledyne-hi.com Digital 300 Series Flow Sensor The Digital 300 Series is built using a patented (Patent #6,125,695) flow sensor. The sensor's excellent linearity, in turn, leads to improved accuracy. Flow calibrations are typically performed in N2 or air. The output can then be scaled for use in other gases (see graph to the right). The 300 Series excellent linearity allows the linearity to be retained when switching from the calibration gas to the process gas. The patented sensor contains fast electronic circuitry. This is critical when the flow meter is coupled with a proportional control...
