The family of B-Series mass flow controllers (photo) is designed to be insensitive to fluctuations in pressure and temperature. Each flow controller is built on a standard 1.125-in.-wide platform with a powerful user interface and local digital display. The mass flow controller actively measures line pressure and adjusts the control valve to virtually eliminate actual flow and flow-signal changes as caused by pressure fluctuations. In addition, the output of every B-Series mass flow controller is characterized over the full operating temperature range. The B-Series incorporates internal self-diagnostic routines that continuously check the health of the device. In the event of a diagnostic fault, an alarm code flashes on the user interface. An easy-to-use service port provides additional diagnostic capability, minimizing the need to remove the mass flow controller from process service. — Brooks Instrument, LLC, Hatfield, Penn.
