The flow is visible at a glance.
This is a current galvanometer that checks the flow of fluid by observing the movement of a ball (or float) inside a transparent tube.
The flow rate cannot be confirmed.

Lightweight aluminum protective cover included
By using cast aluminum, the strength remains the same as the conventional product (MKC type), while the weight has been reduced by more than 50%.
The mounting direction does not matter.
Because it uses a spring inside, you can freely adjust the mounting position to upward, downward, or sideways.
