I know this post is about money, but I want to talk about electronic flow meters than money so I will. The description of "Japanese company making the best electronic flow meters" strongly suggests it is Keyence. They are the best indeed.
Keyence is the 3rd largest Japanese company by market capitalization, next to Toyota and Japan's largest bank (Mitsubishi). Larger than Sony, larger than Nintendo, larger than Honda, etc. Keyence does sensors and nothing but sensors.
If you want to learn about the science of flow meters, you can visit a site maintained by Keyence, Flow Knowledge. Where you read that electromagnetic flow meters (this is proper name for "electronic" flow meters, which may be used for lay audience) detect flow by using Faraday's Law of induction.
Very tangential, but as a worker in Japan I find it depressing how Keyence's recruiting material proudly shows a software engineer's typical day that starts at 8:30AM and ends around 8:00PM. No wonder it's so hard to raise kids.
