Emerson Introduces New Line of Brooks® Mass Flow Meters and Controllers

The Model 4800 Series provides ultra-fast response in a compact instrument

HATFIELD, PENN (January 18, 2006) Emerson Process Management has introduced the new Brooks® Model 4800 Series Mass Flow Meters and Controllers which offer a broad flow range, fast response time, compact size and many other benefits for a variety of applications.

Engineered with a Micro Electro Mechanical System (MEMS) based thermal sensor, the 4800 Series delivers exceptionally fast response to changes in gas flow rate. The MEMS sensor achieves extremely fast response rates compared to typical thermal technologies by allowing the gas to flow directly across the sensor. The compact sensor also enables a dramatic reduction in size compared to traditional thermal mass flow devices.

The Brooks 4800 Series is an excellent choice for measurement and control of many common gases including air, N2, O2, Ar, He, H2, CO2, CO, N2O, CH4, CH3H6, and C3H8. The Model 4850 mass flow controller uses a proprietary PID algorithm to optimize control valve response; this ensures rapid settling times, and quick match of actual mass flow to any changes in setpoint.

The wide flow range, fast response, and compact size of the 4800 Series make these devices a perfect fit for any OEM system where gas flow needs to be measured or controlled. Additionally, the 4800 Series has been designed for modular construction to facilitate quick assembly in order to meet short delivery schedules.

The Model 4800 Series is unsurpassed in reliability and quality. All Brooks products are supported by Emerson's worldwide network of field sales experts and post-sale technical staff.
