Parker Model 513AC Series II Mass Flow Meter is designed for precise measurement of virtually all conventional process gases. The 513AC consists of a thermal mass flow sensor, and microprocessor based circuitry with signal and fieldbus conversion. 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 type of gas and the process conditions of the application.
