量計の誤測定防止回路。The temperature difference between the water supply and the return water from the heat load is detected, and the flow rate of either the water supply or the return water is detected, and the amount of heat consumed in the heat load is calculated by multiplying the temperature difference by the flow rate. A calorimeter for determining the amount of heat is provided with a comparator that compares the voltage indicating the temperature difference with a reference voltage and blocks the transmission of the signal indicating the amount of heat when the voltage indicating the temperature difference becomes less than the reference voltage. A calorimeter measurement error prevention circuit characterized by the following.
