F170 - Level monitor

F170 - Level monitor
with high / low alarms and analog outputs

The F170 is a versatile level indicator featuring continuous level monitoring. It offers the ability to set two low and two high level alarm values. If desired, an ignore function can be set up to allow for an incorrect level for a certain period of time. Up to five outputs are available to transmit alarm conditions and actual level.
The display shows the actual level, height or percentage, alarm values, alarm messages and status. On-screen engineering units are easily configured from a comprehensive selection.
A wide range of options further enhance this models capabilities, including Intrinsic Safety for hazardous area applications and full Modbus communication.

Features
• Level monitoring: four alarm values can be set: low-low, low, high and high-high level alarm.
• Alarm values can be changed by the operator or they can be passcode protected.
• Analog output to transmit the actual level.
• Level and alarm values: six large 17mm (0.67") digits.
• Displays level, height or percentage, measuring unit and alarm messages simultaneously.
• Alarm ignore function allows an incorrect level for a certain period of time.
• Selectable on-screen engineering units; volumetric or mass.
• Displays clear alarm messages.
• Green LED backlight.
• Backup of settings in EEPROM memory.
• Operational temperature: -40°C to +80°C (-40°F to 176°F).
• Very compact design for panel mount, wall mount or field mount applications.
• Rugged aluminum or GRP field mount enclosure IP67 / NEMA4X.

Applications
Level measurement and continuous level monitoring is desired as well as signal re-transmission of the level or serial communication.
