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.
