Description Specifications Literature Video Description See Mass Flow in a Whole New Way! 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 0-25 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 HFC-D-302A & B flow controllers feature a precision solenoid proportional control valve. Teledyne configures and tests each individual valve based on the users flow rate, gas, and pressure conditions. "B" Series—300 Vue The B Series features an optional touchscreen display which allows the user to view and control the flow rate directly from the flow controller. The main screen displays the flow rate, the flow setpoint (in the case of a flow controller), the units of measure, and the valve mode (Auto, Open, Closed). The user also has access to menus that allow quick configuration of the flow instrument for changing requirements. The display can also graphically display in flow over time. The B Series also features a USB port which is standard on all meters and controllers. Both the A & B Series are compatible with Teledyne's data logging software.
