Flowmeters and controllers

By Plant Engineering Staff February 2, 2007

The Brooks Model 4800 series mass flowmeters and controllers offer compact size and other benefits for a variety of applications. Engineered with a micro electro mechanical system-based thermal sensor, the series responds to changes in gas-flow rate because the design allows gas to flow directly across the sensor. It’s suitable for measurement and control of many common gases, including air, N2, O 2 , Ar, He, H 2 , CO 2 , CO, N 2 O, CH 4 , CH 3 H 6 and C 3 H 8 . The flow controllers use a proprietary PID algorithm to optimize control valve response, facilitating settling times and matching of actual mass flow to changes in setpoint.
