SITRANS FUE950

 

The battery or mains powered SITRANS FUE950 is a universal custody transfer approved energy calculator. It is designed for use in hot water, chilled water and cooling/heating applications. The calculator has a modular construction which means that it can be fitted with optional output modules when it is ordered. These include a pulse output, pulse input, current output and an M-Bus add-on module. If needed, the necessary temperature sensor pair and pockets can be ordered along with the calculator. 

 

The SITRANS FUE950 can be used with SITRANS FUS380,  SITRANS FUE380SITRANS FM MAG 5000,  SITRANS FM MAG 6000SITRANS FM MAG 8000  and SITRANS FS220.

 

Application Examples: District heating applications, Chilled water applications, Combined cooling/heating applications
