Single-phase AC Electromagnetic Heat Flowmeter

Heat calculation method and normal working conditions Heat calculation method: This electromagnetic heating and cooling meter follows the urban construction industry standard CJ128-2007 of the People's Republic of China. Heat measurement: When water flows through the integrated heat meter or combined heat meter installed in the heat exchange system, according to the flow rate given by the flow sensor and the water supply and return signal given by the paired temperature sensor, as well as the water flow time, the integrator calculates and displays the cold and heat energy released or absorbed by the system. Fundamental principle The formula is: Formula: Q - Heat released or absorbed by the system, in J; qm - Mass flow of water flowing through the heat meter, in kg/h; qv - The volume flow of water through the heat meter, in m3/h; ρ - the density of water flowing through the heat meter, in kg/m3; Δh - the difference in enthalpy of water at the inlet and outlet temperatu…
