ELISTHERM heat/cold meters measure the absolute values of heat or cold transmitted by heating or cooling water in closed hot water or cooling systems. These systems consist of an ultrasonic or electromagnetic flow meter, paired resistance temperature sensors and a calorimetric counter. They measure and register the amount of heat / cold in water by calculation in a calorimetric counter from the measured water flow and temperature difference of water in the inlet and outlet piping.
They are designed for measuring the energy of heat and cold in liquids in pipes of larger dimensions up to DN1200 (48")
They are specified meters (all elements of the system are metrologically certified)
Long-term stability in measurement accuracy over a wide range of measured values
High reliability and minimal maintenance requirements
Simple operation, intuitive data acquisition for invoicing
Archiving of calculated and measured values for up to one year
Possibility of data transfer to the superior system
Heat meters can be used as commercial meters
