The Doppler Effect Flow meter uses reflected ultrasonic sound waves to measure the velocity of particles in the fluid. By measuring the frequency shift between the ultrasonic frequency source, the fluid carrier, and the receiver, the relative fluid velocity is measured.
How long it took to freeze will have a bearing on it, too. If the ground beef was 3 days old when frozen, you might try cooking it from frozen. If it was freshly ground when frozen, the thawed meat will likely be good for 2 days. Once thawed, the ground meat should be used within a day or two. Ground meat spoils quickly since grinding the meat mixes bacteria throughout.
How soon should beef be cooked after thawing? After thawing beef in the refrigerator, you don't have to cook it right away. Ground beef can be stored an additional 1 to 2 days before cooking; beef roasts and steaks may be stored 3 to 5 additional days before cooking. If beef is thawed in cold water or in a microwave oven, it should be cooked as soon as it is thawed. For more thawing information, go to The Big Thaw. Was this answer helpful?
