Using the Fixed-WALL UFM to measure heat/energy

With the addition of 2 PT100 plug-in modules and clamp-on PT100 temperature sensors the Fixed-WALL UFM from Sonic Driver can make heat/energy measurements.
The meter operates as a mass flow meter, is installed in the return line, uses ultrasound to measure flow rate and clamp-on PT100 temperature sensors to measure the flow and return temperature difference to calculate the hydronic heat/energy load.
The WALL UFM measures energy rate and totalised energy with a Heat/Energy calculation designed to comply with EN1434-1 section 8 and appendix A.
The meter can also make calculations to the Russian GSSSD equivalent.
