• Single Alkaline “D” battery provides power for up to 4 years

• Single Lithium “AA” Backup battery will provide 100% operation for up to 1 year after main

battery is depleted

• Measures & records pressure and temperature sensors every meter revolution or every min

(programmable)

• Continuous LCD defaults to Corrected Volume. Scrolling allows Uncorrected Volume, Pressure,

Gas Temperature, Correction Factor, Main and Lithium Battery Voltage, as well as any active

Alarm to be displayed.

• Non-volatile Flash memory saves Calibration, Transducer Coefficients Configuration & Site info

if all power is lost

• Profiler data recording- Circular log: 130 days/hourly: Time/ Corrected/ Uncorrected/ Ave

Pressure/ Ave Gas Temperature

• Event Log (Records alarms & configuration changes)

• System Alarms (H/L Press, H/L Temp, main and lithium backup battery)

• Contract Usage Alarms (High Day/ Warning Month/ High Month)

• Contract Management (Nomination/ Allocation)
