Flow Computers \ Flow Computers \ Mass Flow Computer For Steam Gas and Energy EMCO FP93

EMCO's FP93 unit is a microprocessor-based instrument for monitoring a variety of flows in an industrial environment.

This programmable flow processor and remote terminal unit accurately calculates volume; mass and heat flow rates for steam, liquids, and gases and displays these variables in user-selectable, engineering units. Pressure and/or temperature compensation and an 8-point flow calibration curve may be used to enhance performance. Diagnostic routines constantly monitor the FP unit's performance, and the detection of a fault is automatically displayed.

Features:

• Single-board design for high reliability and low cost
• Displayed values with description and user-selectable engineering units
• Non-volatile memory for programmed data
• Isolated outputs for digital and analogue control
• 16-bit resolution A/D converter for superb analogue accuracy
• Battery-backed memory for statistical values and totalizers
• Self diagnostics and operational alarm monitoring
• Panel-mount unit or optional NEMA 4 enclosure
• Backlit display for viewing in all lighting conditions
