DESCRIPTION
The Brooks® Models MT 3809 and MT 3819 Variable
Area Flowmeters are rugged, all metal flowmeters
offering 2% full scale accuracy. The Model MT 3809 is
constructed with stainless steel components for
measuring a variety of gas, liquid and steam
applications while the Model MT 3819 utilizes a
ETFE (Tefzel™) lining for aggressive 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.
Also available are front adjustable inductive alarms,
high temperature or stainless steel indicator housings,
valves, flow controllers and material certifications.
