PURPOSE: A remote meter-reading apparatus capable of showing the meter-reading results by each family is provided, thereby displaying the each amount of electric power, water, gas, hot water, heating used by each family on one panel at the same time. CONSTITUTION: The remote meter-reading apparatus capable of showing the meter-reading results by each family consists of a meter-reading part which reads the signal of voltage in proportion to the voltage loaded in the electric power-providing line of each family; a controlling part which has an input/output separate circuit displaying separately the amount of the electric power used by each family; a gauge showing the pulse signal detected from the meter-reading signals of water, hot water, gas and heating/cooling-supplying line; a microprocessor comparing and controlling the pulse signals from the gauge; and a displaying part which displays sequentially the meter-reading values of the each amount of electric power, water, hot water, gas and heating/cooling used in each family.
