Description
The F112 is a versatile indicator and totalizer featuring 15-point linearization for enhanced accuracy across the entire flow range. It interpolates between entered points, affecting all displayed data and output signals. With integrated Modbus RTU, analog, and pulse outputs, it is ideal for mechanical flowmeters requiring precise local and remote monitoring.
Features
- Simultaneous display of linearized flow rate, resettable running total, and non-resettable accumulated total
- 15-point linearization of the flow curve with interpolation; applies to display, pulse output, and analog output
- Suitable for very low frequency pulse applications
- Scaled pulse output reflecting linearized accumulated total; configurable pulse scale (e.g. one pulse per 3.25 GAL)
- Analog output retransmitting linearized flow rate; scalable to any range
- Remote control input: external total reset or keypad CLEAR disable
- Selectable large digit mode: flow rate or total displayed at 17 mm (0.67″”) height
- Flow rate: 7 digits at 17 mm (0.67″”) or 8 mm (0.31″”)
- Running total: 7 digits at 17 mm (0.67″”); resettable via double CLEAR button press
- Accumulated total: 11 digits at 8 mm (0.31″”); non-resettable
- Separate on-screen engineering units for flow rate and total
- Modbus RTU communication via RS232, RS485 2-wire or 4-wire, or TTL
- LED backlight with adjustable intensity
- Auto backup of settings and running totals in EEPROM memory
- Available in GRP, aluminium, or high-grade stainless steel enclosure
- Ambient temperature: −40 to +70 °C (−40 °F to +158 °F)
- Various accessories available
Applications
- Liquid flow measurement with mechanical flowmeters requiring precise linearized calculation over the full measurement range
- Applications requiring flow rate and/or totalizer retransmission alongside serial communication
- Low frequency pulse applications demanding enhanced linearity
- Harsh outdoor environments: rain, snow, sand, salt atmosphere
- Oil and gas, chemical, and process plant field installations
- Safe and hazardous area installations
