Emerson Process Management Rosemount Volumetric Output Flowmeters, Product Specification Sheet

Product Specification Sheet

00815-0100-4810, Rev AA June 2005

Functional Specifications

•The pressure instrument shall have the capability to be supplied as mounted directly on the COP primary when the process temperature is less than 450°F (232°C).

•Differential pressure instruments shall be capacitance technology-based.

•The pressure instrument sensor shall be hermetically sealed from the external environment.

LCD Specifications

•The instrument indicator shall be LCD type. It shall display the numeric value and also have a 0-100% scale bar graph corresponding to the analog output. It shall be possible to configure the indicator to display more than one parameter (pressure, scaled output); in this case the display will toggle / scroll to show all selected parameters. The indicator will display all alarms and alerts.

•The pressure instrument shall have built-in transient protection.

Communication Specifications

•Communication with the flowmeter can occur via a hand-held device.

•Digital communication with the flowmeter shall

be via open protocols (e.g. HART, FOUNDATION™ Fieldbus). Proprietary protocols are not permitted.

•The flowmeter shall allow field upgrading of communication protocols and the addition of advanced instrument software functions without changing the pressure sensor.

Software Specifications

•The flowmeter shall contain user definable low flow cut-off functionality.

•The pressure instrument shall be able to fully communicate with a Microsoft® Windows® based instrument management software via an open communication protocol.

•It shall be possible to store last calibration date and next calibration due date in the pressure instrument memory using a hand held configurator. This information should be available on Windows-based instrument management software.

•All instruments shall retain original factory calibration settings in a permanent memory. It shall be possible to recall this calibration using a hand-held communicator.

Volumetric Output Flowmeters

A volumetric measurement is ideal for liquid fluid types.

When the COP is integrated with a differential pressure instrument for volumetric output, the flowmeter shall perform as follows:

•Within ± 0.75% to ± 0.95% of flow rate, dependant on beta size.

•The vendor shall make independent testing documentation available demonstrating this performance.

Functional Specifications

•Pressure instrument hardware / software failure alarm shall be selectable as high, low, or any user-defined value.

•The flowmeter shall have the ability to detect impulse line plugging or should allow field upgrading to include this by the addition of an electronics card.

Software Specifications

•The flowmeter shall allow the digital output of

the pressure instrument to be scaled to any user-defined unit (e.g 0-200 m3/hr, 0-9000 gallons/min).

•The flowmeter shall allow custom user-entered digital alerts for both high and low values for the pressure reading. This digital alert will not affect the analog output.

•Flowmeters for custody transfer will have hardware and software write protect security. Hardware security will override software.

LCD Specifications

•It shall be possible to remote mount electronics with a display up to 100 ft (30 m) from the pressure sensor. These electronics will allow full configuration of the instrument via a hand-held communicator.
