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.
In the refrigerator, ground beef, stew meat, and steaks may thaw within a day. Bone-in parts and whole roasts may take 2 days or longer. Once the raw ground beef thaws, it will be safe in the refrigerator for 1 to 2 days.All other cuts of beef can be refrigerated safely for 3 to 5 additional days before cooking.one-in parts and whole roasts may take 2 days or longer.
