FLOW COMPUTER APPLICATION
• Turbine flowmeter sends digital signal to
Flow Computer
• 100W RTD direct hook-up to Flow Computer
(4020 Only)
• Flow Computer Linearizes, Temperature
Compensate (4020 Only) and calculates
corrected Flow Rate & Total
• Scaled pulse out to remote totalizer in
supervisory area
• 4-20 mA out, corrected flow rate, to strip chart
recorder tracks trends
• Alarm relay and transition outputs to activate
bell and/or light as needed
