Brooks Instrument announces MT3809 variable area (VA) flow meter with FOUNDATION Fieldbus transmitter

March 15, 2018 –Brooks Instrument has added a FOUNDATION Fieldbus transmitter to its MT3809 variable area (VA) flow meter, for users to integrate the unit into their automation control systems for data capture and digital communication across the plant enterprise.

The Brooks Instrument MT3809 metal tube VA flow meter is designed for extreme conditions in chemicals, petrochemicals, oil and gas, and LP gas applications.

The FOUNDATION Fieldbus transmitter is a 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 transmitter is designed to ease access to multiple MT3809 VA flow meter variables, including:

  • Flow rates
  • Totalization, both resettable and inventory measurement
  • Temperatures
  • Densities
  • Calibration factors
  • 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 MT3809 VA 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 FOUNDATION Fieldbus transmitter on the Brooks Instrument MT3809 VA flow meter is equipped with the FOUNDATION Fieldbus protocol, ITK 6.0. The transmitter and alarm options have worldwide safety approvals as well as SIL 2 safety certification.

With the MT3809 VA flow meter, users can specify a single flow meter model that works across a range of high and low flow rates and operating temperatures — from -198ºC to 420ºC (-325ºF to 788ºF) — with a maximum pressure rating up to 6,000 psi (413 bar) for standard units. In addition, the explosion-proof housing meets hazardous-area classifications while a flameproof option is available for IIC/Class 1, Division 1 locations.
