To readily measure the energy input quantity of facility apparatus that uses steam as energy source, without cutting pipes.
The temperature of steam flowing into an absorption refrigerating machine 1 is measured, and inlet side steam enthalpy is determined. The temperature of steam condensate outputted from the absorption refrigerating machine 1 is measured, and output side steam enthalpy is determined. An ultrasonic flowmeter 19 for liquid use is mounted on the surface of a vertical tube 15 in which the steam condensate flows, and the flow rate of the steam condensate is determined. Resultantly, steam energy inputted into the absorption refrigerating machine 1 can be determined, by subtracting the output side steam enthalpy from the inlet side steam enthalpy, and multiplying the result by the flow rate of the steam condensate.
