Spanish term or phrase:mirilla indicadora
This appears in a maintenance standard for an air dryer. It is a little peephole that you can look into to inspect the level of a product (I'm not sure if it's a liquid or a powder or what). I was thinking of using "level indicator" but I think that could include a whole range of devices. I want something that means "tiny window you can look into to see how much product is left"...I know we must have a word for it...anybody know it?
