Brooks Instrument's B-Series mass flow controller ignores fluctuations

March 11, 2009 - Brooks Instrument released the B-Series mass flow controller that is insensitive to fluctuations in pressure and temperature. Built on a standard 1.125-inch wide platform with a powerful user interface and local digital display, the B-Series provides a compact flow measurement and control solution which eliminates the need for costly temperature and pressure control devices and systems.Immune to Pressure and Temperature FluctuationsThe B-Series is a pressure- and temperature-insensitive device. The mass flow controller actively measures line pressure and adjusts the control valve to virtually eliminate actual flow and flow signal changes as a result of pressure fluctuations. In addition, the output of every B-Series mass flow controller is characterized over the full operating temperature range of the device allowing superior measurement and control accuracy regardless of process or ambient temperature conditions.Unique Advanced DiagnosticsThe B-Series incorporates sophisticated 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.
