Measuring Features
?
Water will release heat if temperature decreases. Released heat is ratable with temperature difference and flow volume through meter. Flow volume signal comes from flow sensor, temerature difference comes from temperature sensor pair, as result the calculator will calculate heat according to the flowing volume and temperature difference.
