Enhanced Mass Flow Meters/Controllers Offer Digital Communications and a Downport Connection Option

Brooks Instrument announces several updates to its line of mass flow meters/controllers. The 4800 Series now offers digital communication via an RS-232 protocol and a downport connection option. It is also the first of Brooks' mass flow devices to be fully RoHS compliant.

The RS-232 one-to-one digital communication protocol allows customers to provide a setpoint and receive the process value, select one of nine gases for the calibration curve, access the valve override function and access the re-zero function. The RS-232 protocol comes built into the product as part of its standard package.

Optional downport connections are now available on the Model 4800 Mass Flow Meter/Controller. In order to keep the 4800 Series' small footprint, Brooks utilized a proprietary standard downport option. This option allows top mounting for ease of maintenance and installation and also offers additional space over traditional mountings because there is no point-to-point tubing necessary.

The RoHS Directive places restrictions on the use of certain hazardous substances in electrical and electronic equipment. This directive bans new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury and certain other materials from being distributed in the EU. The 4800 Series is Brooks' first, fully RoHS compliant MFC.
