NIVELCO N H Series User Manual

Thank you for choosing NIVELCO instruments.
We are convinced that you will be satisfied with our product.
1. APPLICATION
NIVOPRESS N submersible hydrostatic level transmitters are applicable for the continuous level measurement of clean
liquids or liquids with slight chemical contamination in wells, open reservoirs or tanks. The NC is recommended for level
detection of contaminated water. NIVOPRESS N is easy to install in tanks and deep wells, and especially recommended
for controlling submersible pumps. The use of supplemental accessories is recommended. Using a sewage adapter direct
contact between the sewage and the diaphragm of the built-in pressure sensor can be avoided. 2-wire types are available
with built-in 4-wire Pt100 temperature sensor or separate 2-wire temperature transmitter. 2-wire types have HART
communication interface. The Ex-types are available for explosion hazardous environments.
