WMZ Plus Calorimeter
Universal calorimeter module for solar, heating and cooling systems. Graphic display for indication of flow and return temperature, heat quantity, flow rate and sensor faults (balance values are also stored in case of a power failure). Suited for systems with water or water-glycol mixtures (water, propylene glycol, ethylene glycol and Tyfocor® LS adjustable).
