Expand the Capability of Flow Measurement

Technology

Expand Capabilities

The Rosemount Flow Computer satisfies the instrument requirements for a variety of flowmeter types in liquid, gas,

steam and heat applications. Multiple flow equations are available in a single instrument with many advanced features.

Easy To Use

The alphanumeric display offers measured parameters in an easy to understand format. Manual access to

measurements and display scrolling is supported.

Versatile

The versatility of the Flow Computer permits a wide measure of capabilities within the instrument package. The various

hardware inputs and outputs can be ¡°soft¡± assigned to meet a variety of common application needs. The user ¡°soft

selects¡± the usage of each input/output while configuring the instrument.

Adaptability

The isolated analog output can be chosen to follow the volume flow, corrected volume flow, mass flow, heat flow,

temperature, pressure, or density by means of a menu selection. Most hardware features are assignable by this

method.

The user can assign the standard RS-232 Serial Port for external data logging, transaction printing, or for connection to

a modem for remote meter reading.

Simplified Verification

A Service or Test mode is provided to assist the user during start-up system check out by monitoring inputs and

exercising outputs. The system setup can also be printed.
