DL/N.Mini Level and temperature logger with radio-transmission
The product portfolio for the water level and groundwater industry has been expanded with the DL/N.Mini which is another highly efficient and reliable short-range radio data logger. It measures both the pressure and the temperature in the medium with an accuracy of 0.1%FS. The system consists of a data logger and a pressure sensor mounted on the cable end. The DL/N.Mini can be used in river, lakes, canals or ground water.
Communication
The DL/N.Mini is operated as a standalone system and can in combination with the WMS, generate a network of up to 24 loggers. In this system, the WMS acts as a kind of router and transmits the collected measurement data via GSM/GPRS to the corresponding server. Without an additional WMS, the Mini is conveniently monitored and operated via local radio interface. The system can be expanded at any time even after installation.
