Brooks Instrument, one of the leaders in precision fluid measurement and control technology across the globe, has added a new Foundation Fieldbus transmitter to its popular MT3809 variable area (VA) flow meter. According to the company, this will make it easier for users to integrate the unit into their automation control systems for more efficient data capture and digital communication across the plant enterprise.

The MT3809 metal tube VA flow meter is designed for extreme conditions in chemicals, petrochemicals, oil and gas, and LP gas applications. Proven to deliver reliable, repeatable gas and liquid flow measurement and control in thousands of installed locations, the flow meter is a practical and economical ‘go-to’ choice for engineering procurement contractors and specifiers for major industrial facilities worldwide, states the organisation.

Rich Data Available with Foundation Fieldbus Interface

The Foundation Fieldbus transmitter is a compact microprocessor device that interfaces directly with the MT3809 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 company opines that the new transmitter makes it easier to access multiple MT3809 VA flow meter variables, including flow rates, totalization, both resettable and inventory measurement, temperatures, densities, calibration factors and hi-low alarm parameters, which enable facilities and systems operators to be notified if gas or fluid flow rates fall outside set values.

In addition, the flow meter has a local operator interface with LCD display for insight into flow status and fluid measurement. These outputs are configurable and can be shown in various engineering units. Operators can also change parameters without removing the housing cover, enabling changes to be made in hazardous areas.

The transmitter on the MT3809 VA flow meter is equipped with the most up-to-date version of the Foundation Fieldbus protocol, ITK 6.0. The transmitter and alarm options have worldwide safety approvals as well as SIL 2 safety certification, claims the firm.
