Yokogawag Real-Time Dynamic Compensation for Static Pressure Effects

DP TransmittersAccurate measurement is vital to efficient plant operation and plant safety. When selecting a transmitter, a lot of attention is paid to the Reference Accuracy noted in supplier's specification documents. Reference Accuracy gets its name because the accuracy is based on a set of reference conditions. The reference conditions dictate a certain temperature, humidity, and static pressure for the Reference Accuracy to be measured in a laboratory setting. In the real world, DP Transmitters are rarely installed in a laboratory and never under the rigid confines of those reference conditions; therefore, Real-world Performance (RWP) is always worse than the Reference Accuracy. To improve RWP, all smart transmitters on the market compensate for variations in temperature; but, Yokogawa's sensor used in the EJA-A series, EJX-A series, and EJX-B series is unique in the market place because it can compensate for effects in static pressure change as well. This ability is referred to
Real-time Dynamic Compensation.

How to Connect the Brooks Instrument MT3809 Variable Area Flow Meter (Rotameter) with FOUNDATION™ Fieldbus Transmitter to Your Network

Brooks Instrument MT3809 Variable Area Flow Meter
MT3809 Variable Area Flow Meter
Brooks Instrument has added a new FOUNDATION™ Fieldbus transmitter to its popular MT3809 variable area (VA) flow meter, making 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 is also EMERSON™ qualified for its Delta V control system and AMS device manager.

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 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
  • 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 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.
