Zusammenfassung:	THERMAL POWER MEASUREMENT APPARATUS Measuring apparatus for a system which includes a heat source such as a nuclear reactor and a utilization means such as a steam generator connected by first and second fluid conveying ducts in a closed circulation loop. A multi-path acoustic flowmeter in one leg of the loop obtains an indication of volumetric flow rate as well as an indication of the speed of sound in that leg. A multi-path acoustic measuring apparatus in the other leg obtains an indication of the speed of sound in that leg and electronic circuitry is provided for modifying the indications and combining them to obtain total thermal power.
