Brooks Instrument has released the B-Series mass flow controller, a family of mass flow products designed to be 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.
The 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.
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.
