The sensor module from MCQ is designed to used for measuring and controlling of mass flow. This device allows the user to create a mass flow controller that meets their own features. The board mounts an operational amplifier, an analog filter and a DSP micro-controller that recognized the data recovery, the digital filtering, the linearization and the thermal reimbursement. The DSP micro-controller can be programmed to accomplish the PID control to manage the valve in answer to the information gathered by the flow sensor mounted on board.
