NIVELCO NIVOPRESS NPK - User Manual

Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use.
1. APPLICATION
The NIVOPRESS submersible hydrostatic level transmitter is applicable for the continuous level measurement of clean
or chemically faintly contaminated liquids in bored well, open reservoirs and tanks. The NIVOPRESS is easy to install in
already existing tanks and in deep bored well and is especially recommended for controlling of submersible pumps.
