The iLevel-GW Mini is a groundwater datalogger for measuring and storing water level and temperature.

The iLevel-GW Mini is suitable for long-term recording of groundwater data such as water level or temperature. It is available as 1” or 2” version. The autonomous level logger has an internal barometer sensor and measures the water pressure via an absolute pressure sensor. The water level is determined by a counter calculation of the measured absolute pressure and the air pressure.

The measured values are recorded at freely adjustable intervals and can be conveniently read out on site via near-field radio communication (433 MHz) using a laptop. With the free of charge operating software, the user can configure the logger, enter the cable plumb reference value and retrieve the data.

Operation
The device is perfectly suitable for battery operation: Low power components allow for ultra long operation up to 10 years. The event control feature allows to freely adjust threshold values. When exceeding or falling below these values, the logger can switch to a faster measuring interval.

  • Versions for installation in water level pipes 1” or 2”
  • Pluggable pressure sensor incl. temperature sensor
  • Memory for 250.000 measurement series
  • Batteries (lithium) changeable on site
  • Operation life up to 10 years
  • Local configuration via near field communication
