F073 - Level monitor

F073 - Level monitor
with one high / low alarm output

The F073 is a versatile level indicator with continuous level monitoring feature. It offers the ability to set one low level and one high level alarm value. If desired, an ignore function can be set up to allow for an incorrect level for a certain period of time. The configuration of the Span, off-set and number of decimals is done through software functions, without any sensitive DIP-switches or trimmers. 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.

Features
• Displays level and height or percentage filled.
• Level monitoring: two alarm values can be set: low and high level alarm.
• Alarm values can be changed by the operator or they can be passcode protected.
• One alarm output for high, low or both combined level alarms.
• Level: six large 17mm (0.67") digits.
• Selectable on-screen engineering units for level:
ml, L, m³, GAL, USGAL, kg, lb, bbl or no unit.
• Selectable on-screen engineering units for height:
mm, cm, m, mtr, inch, ft, mmwk, mmwc, cmwk, cmwc, mwk, mwc, inwc, ftwc, mBar, Bar, PSI or no unit.
• Red flashing LED backlight in case of a level alarm; intensity adjustable.
• Displays clear alarm messages.
• Auto 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.
