Brooks Instrument has added a new Foundation Fieldbus transmitter to its MT3809 variable area (VA) flow meter. The metal tube VA flow meter is designed for extreme conditions in chemicals, petrochemicals, oil and gas and LP gas applications.
The Brooks Instrument transmitter is a compact microprocessor device that interfaces directly with the flow meter. A single 2-wire bus connection compliant with the international Foundation Fieldbus standard provides power to the transmitter and communications access. The flow meter itself does not require power.
The transmitter is said to make it easier to access multiple flow meter variables, including:
- flow rates;
- totalization, both resettable and inventory measurement;
- calibration factors; and,
- hi-low alarm parameters.
The transmitter and alarm options have worldwide safety approvals as well as SIL 2 safety certification.
Units can operate from -198° to 420°C — with a maximum pressure rating up to 6,000 psi for standard units.
In addition, the housing meets most hazardous-area classifications worldwide, while a flameproof option is available for IIC/Class 1, Division 1 locations.
