F111 - Dual input flow rate indicator / totalizer

F111 - Dual input flow rate indicator / totalizer
with two pulse outputs

The F111 incorporates two flow rate / totalizers in one enclosure, including a pulse output for each flow. There is no relationship between the flows, even different pulse signal input types can be used.
For each flow, on-screen engineering units are easily configured from a comprehensive selection. The F111 can be set to show the selected information manually or with an automatic toggle function.
A wide range of options is available to further enhance this models capabilities, including Intrinsic Safety for hazardous area applications and full Modbus communication.

Features
• Two competely separated flow rate / totalizers.
• For each flow one scaled pulse output.
• Displays total, flow rate and product I.D. simultaneously.
• Large digit selection for flow rate or total.
• Flow rates: seven 17mm (0.67") or 8mm (0.31") digits.
• Totals - resettable: seven 17mm (0.67") digits.
• Accumulated totals - not resettable: eleven 8mm (0.31") digits.
• Separate engineering units for flow rates and totals on the display.
• Green LED backlight.
• Auto backup of settings and running totals in EEPROM memory.
• Operational temperature: -30°C to +80°C (-22°F to 178°F).
• Very compact design for panel mount, wall mount or field mount applications.
• Rugged aluminum or GRP field mount enclosure IP67 / NEMA4X.

Applications
For those applications where two indicators are required but one single and compact enclosure is desired.
Alternative basic model: two separate F014’s.
