SITRANS FUE950 Energy Calculator

Brand: Siemens AG

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.
