NIVUS - Model NLM0PDS0 -Water Level Autarcic Data Logger

• 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

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.
