1 Brooks® Model MT 3810 Data Sheet DS-VA-MT3810-eng March, 2008 Metal Tube Variable Area Flowmeter with Optional Electronics based on Smart Meter Manager™ Technology GENERAL FEATURES • Broad range of flow capacities • 5% Full scale accuracy • Versatile construction for all gas and liquid applications • No back pressure required for operation • Flanged or female NPT connections • Optional 4-20 mA and HART® programmable microprocessor transmitter with or without alarms and pulse output for totalization • Electronics designed with either intrinsically safe or explosion proof construction to meet UL (US & Canada) ATEX certifications and CE requirements DESCRIPTION The Brooks® Model MT 3810 Variable Area Flowmeter is a rugged, all metal flowmeter offering 5% full scale accuracy. The MT 3810 is constructed with stainless steel components for measuring a variety of liquid and gas applications. Flow rate indication is provided by means of magnetic coupling where a magnet, encapsulated in the float, is coupled to a rotatable magnet located in the rear of the indicator, thus turning the dial indicator mounted on the meter. Optional accessories available include 4-20 mA output with HART microprocessor transmitter with or without configurable alarms and pulse output for totalization. The microprocessor electronics are based on the proprietary Smart Meter Manager technology utilized as the basis for an array of Brooks products. Also available are front adjustable inductive alarms.
