Nivopress NPK - General Purpose.

Nivopress NCK
Nivopress NCK - Sewerage/Black water.

Description:

Nivopress NPK / NCK level probes are 2-wire 4~20mA submersible transmitters used for the hydrostatic measurement of levels in liquids.
The pressure is converted into an electrical signal.
Applications include: level measurement in wells, boreholes, wastewater plant, vessels, and standing or running water.
