SITRANS FUE950 Energy Calculator
Process Instrumentation
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.
