NIVELCO NIVOTRACK MT 2 Series User Manual

Thank you for choosing a NIVELCO instrument
We are sure that you will be satisfied with it throughout its use
1. APPLICATION
NIVOTRACK MT -2 series float type magnetosrictive level transmitter is a two-wire precision measuring
instrument for clean liquids both in normal and hazardous location. These instruments re quire minimum
maintenance since the float is the only moving part.

3. INSTALLATION
The NIVOTRACK MT -2 should be
located in an area, which allows easy
access for service, calibration and
monitoring. Accuracy of
measurement will be affected by
waves on the surface or excessive
vibration. Therefore the instrument
should be located away from the inlet
and outlet as far as possible. The
process fluid should be free of any
suspended solids or material that could stick between the float and the guide rod. If used at
temperatures in exess of 70 °C the maximum ambient temperature allowed will be in
accordance with the derating diagram.
