The Brooks? models MT 3809 and MT 3819 variable area flowmeters are rugged, all metal flowmeters offering reliable operation with class 1.6 accuracy. The model MT 3809 is constructed with stainless steel components for measuring a variety of liquid and gas applications while the model MT 3819 utilizes an E/TFE 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. The microprocessor electronics are based on the proprietary Smart Meter Manager (SMM) technology utilized as the basis for an array of Brooks products. Also available are front adjustable inductive alarms, high temperature or stainless steel indicator housings, valves, steam jacket, flow controllers and material certifications.
