1-1 Description
The Brooks ® Model MT 3810 Variable Area Flowmeter is a rugged, all
metal flowmeter offering 5% full scale accuracy. The Model 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
TM technology utilized as the basis for an
array of Brooks products. Also available are front adjustable inductive
alarms.
