Parker’s Model 603AV Series II Mass Flow Controller (MFC) is designed for precise control of virtually all conventional process gases. The MFC consists of a thermal mass flow sensor, a precise control valve and a microprocessor based PID controller with signal and fieldbus conversion. Based on the setpoint input value, the flow controller swiftly adjusts to the desired flow rate. The mass flow rate is provided as analog signal or digitally via RS232 or various fieldbus options. Each unit is specifically sized and calibrated depending on the types of gas and the process conditions of the application.
