NivuLevel 150 is a self-sufficient level measurement system for
use on measurement sites without public power supply. Due to
very low energy consumption the system provides very long
lifetimes. System programming and data readout can be carried
out very easy via USB interface.


The NivuLevel 150 measurement system acquires the parameters level and temperature. It consists of a datarecording module and a hydrostatic submersible pressure probe.

Depending on the memory cycle selected, the system lifetime is up to 5 years.The unit is powered using standard batteries (Type AA) which can be replaced
by the user on site.

This ensures efficient and economical operation over many years. Recorded data are saved in an internal memory and can be read out using the USB interface.
The capacity of the internal memory is approx. 1.000.000 readings. Once provided as CSV files, the readings can be processed further quickly and easily
