Autarcic Data Logger

Level Data Collector

Part No. NLM0PDS0

Level measurement with remote data transmission via GPRS

Water level data logger for groundwater level measurement and GPRS data transmission in level pipes starting at 2“. System life up to 10 years.

  • Extremely robust stainless steel enclosure, IP68
  • Data transmission via GPRS
  • Automatic log-on with the most powerful service network without additional costs
  • Extra-long lifetimes (typical 10 years) through MicroPower® technology
  • Connection clamps for 2-wire system such as pressure probes

General description

Robust measurement system, consisting of transmitter and level probe, for data transmission to the server-based Internet portal "D2W" (Device to Web) via GPRS.

The water level data logger measuring and data recording system is for detection of analog readings from connected 2-wire sensors such as pressure probes. The measurement system operates independent from mains power. Sensor and radio transmission system are powered by high-performance Lithium batteries featuring a very long lifetime (approx. 10 years typical). Detected readings are saved on flash memory and will be transmitted to the server-based Device to Web (D2W) Internet portal via GPRS using the built-in quad band modem.

This Internet portal allows to adjust the settings for communication and data processing as well as the operational settings of the level data collector unit. One of the main benefits of the water level logging system is the option to connect generally all 2-wire sensors by using the integrated terminal clamps. Users hence may select the appropriate sensor for the respective application and, by connecting with the level data connector, obtain a complete measurement system.

Typical level data collector applications

  • Groundwater level measurement
  • Landfill level monitoring
  • Raw water level for waterworks
  • Levels in conservation areas and similar
