Brooks Instrument Variable area flowmeters with fieldbus transmitter
The MT3809 variable area flowmeter includes a Foundation Fieldbus transmitter, a compact microprocessor device that interfaces directly with the flowmeter and makes it easier to integrate the unit into an automation control system. A single two-wire bus connection compliant with the international Foundation Fieldbus standard provides power to the transmitter and communications access. The flowmeter itself does not require power. The transmitter facilitates access to multiple flowmeter variables, including flow rates; totalization, both resettable and inventory measurement; temperatures; densities; calibration factors; and high-low alarm parameters that enable facilities and systems operators to be notified if gas or fluid flow rates fall outside set values.
