Product detailsThe SOM WMZ SOL is a universal heat meter for solar thermal systems and conventional heating systems. It captures both the temperature and the mixing ratio of the water and glycol. The flow and return temperatures are captured by two PT 1000 temperature sensors. The LCD can show the temperature at a specific test point, the heat absorbed, the current output or the system flow rate. The heat meter comprises a display module, two temperature sensors incl. sensor wells, and a flow meter.
