I want to do some research on meter numerical identification. Where can I find information about the meters similar to the one shown below?
Where I can find other images of meters similar to the image above?
You do not tell us how many images you need, I assume you only want some.
In that case just do an image search on Google Images.
When I did this Google responded with the suggestion that this is about a gauge:
Your next step would then be to replace the word gauge in the top search bar with more specific terms like oil gauge or oil level meter and repeat the search with that refinement.
Finally, click on Visually similar images to see all the results, and download them one by one.
Please note that there may be copyright issues depending on how you want to use those images.
