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.
Storage time depends on how old the beef is when you put it in your refrigerator. Most manufacturers have a âuse byâ or âsell byâ date stamped on the package, and may have a packing date as well. If the ground beef is kept under constant refrigeration, you can safely keep it in the refrigerator until the âuse byâ date. If the package has a âsell byâ date, the ground beef is usually good for one to two days after this date.
