Core Function of This Flow Computer

The Emerson Floboss S600 performs precision flow calculations for hydrocarbon measurement. This flow computer accepts inputs from multiple meter types and transmitters. It calculates volume, mass, and energy flow rates in real time. Consequently, the module meets API and AGA standards for custody transfer.

Physical Dimensions and Enclosure Design

This flow computer measures 310 mm in total height. Its width reaches 230 mm for a panel-mount form factor. The unit depth stands at 120 mm including the backplate. You will find a total of 1,280 discrete components across three internal PCBs. These include a 32-bit processor, analog inputs, and communication modules. The Emerson Floboss S600 weighs approximately 3.2 kilograms for industrial durability.

Processor and Memory Configuration

The Emerson Floboss S600 houses a 32-bit ColdFire processor core. This CPU executes flow calculations at 80 MHz clock speed. The unit contains 16 MB of flash memory for firmware and configurations. It also includes 8 MB of battery-backed SRAM for historical data. A replaceable lithium battery preserves this data for up to two years. The computer does not use removable storage cards.

Input Channels and Meter Compatibility

This flow computer accepts six analog input channels for pressure and temperature. It also provides four frequency input channels for turbine and positive displacement meters. Furthermore, the unit supports two RTD input channels for direct temperature sensing. Each analog channel offers 24-bit resolution for high precision. The computer works with Coriolis, ultrasonic, and vortex flow meters.

Output Channels and Control Functions

The Emerson Floboss S600 provides four analog output channels for valve control. It also offers eight digital output channels for alarms and pulse relaying. Each digital output sinks up to 250 mA at 24 V DC. The unit includes two relay outputs for emergency shutdown functions. Four status LEDs indicate power, communication, and alarm conditions.

Communication Ports and Networking

This flow computer offers two RS-232 ports for local configuration. It also provides two RS-485 ports for Modbus RTU networking. Furthermore, the unit includes one Ethernet port for Modbus TCP communication. A dedicated USB port supports firmware updates and data export. The computer supports HART pass-through on all analog input channels.

Energy Storage and Power Requirements

The Emerson Floboss S600 draws 750 mA from a 24 V DC power supply. It also includes an internal switching regulator for logic voltages. The unit incorporates four 1,000 µF electrolytic capacitors for bulk energy storage. Total stored energy reaches approximately 1.8 joules at nominal voltage. The computer dissipates 18 W of heat during normal operation.

Installation and Compliance Notes

You must mount this flow computer in a non-hazardous control room. Always connect a shielded power cable for electrical noise immunity. Then, verify that each meter pulse input matches the frequency range. The unit complies with API MPMS Chapter 21 and AGA Report No. 9. Regular battery replacement every 18 months prevents data loss during power outages.
