You can tell from the context whether the animal or the meat is meant. If people are talking about agriculture, animals in a pasture, or using the plural 'Rinder' (cattle), the animal is meant. If it is about cooking, eating, or shopping at the butcher's, the meat is meant.
Der Bauer hat seine Rinder auf eine neue Weide getrieben.
The farmer drove his cattle to a new pasture.
'Rind' (cattle) is a general term. It can refer to male animals ('Bulle' (bull), 'Ochse' (ox)) and female animals ('Kuh' (cow)). If you do not want to specify the sex, 'Rind' is the right choice.
Die Rinderzucht ist ein wichtiger Wirtschaftszweig in dieser Region.
Cattle breeding is an important economic sector in this region.
When 'Rind' (beef) stands for meat, it is used like an uncountable material and always appears in the singular without an article. You can simply say 'Rind essen' (to eat beef) without having to add the word 'Fleisch' (meat).
Isst du lieber Rind oder Schwein?
Do you prefer beef or pork?
cow
'Kuh' and 'Rind' are very closely related. 'Rind' is the general umbrella term for this type of animal and can include cows, bulls, and oxen. 'Kuh' is more specific and means an adult female bovine. The words can be confused because a cow is always a 'Rind'. But not every 'Rind' is a cow. If the sex of the animal is not important, 'Rind' fits. If you mean the female animal or are talking about milk, 'Kuh' is more precise.

Auf dem Schild stand, dass jedes Rind auf dem Hof genug Platz haben muss.
The sign said that every head of cattle on the farm must have enough space.
Nach dem Füttern brachte der Bauer die Kuh zurück in den Stall.
After feeding it, the farmer brought the cow back into the barn.
