A flowing water optical power meter for measuring multi-kilowatt laser emission has been built and operated. The design and operational details of this primary standard are described, and a full uncertainty analysis is provided covering the measurement range from 1 kW to 10 kW with an expanded uncertainty of 1.2 %. Validating measurements at 5 kW and 10 kW show agreement with other measurement techniques to within the measurement uncertainty.
