Thank you for choosing a NIVELCO instrumentWe are sure that you will be satisfied with it throughout its use1. APPLICATIONNIVOTRACK MT-2 series float type magnetosrictive level transmitter is a two-wire precision measuringinstrument for clean liquids both in normal and hazardous location. These instruments re quire minimummaintenance since the float is the only moving part.2.

INSTALLATIONThe NIVOTRACK MT-2 should belocated in an area, which allows easyaccess for service, calibration andmonitoring. Accuracy of themeasurement will be affected bywaves on the surface or excessivevibration. Therefore the instrumentshould be located away from the inletand outlet as far as possible. Theprocess fluid should be free of any 704513070°C°CMedium temperatureAmbient temperaturesuspended solids or material that could stick between the float and the guide rod. If used attemperatures in exess of 70 °C the maximum ambient temperature allowed will be inaccordance with the derating diagram.
