Maeda Koki MKC Type Oil Signal
Made in Japan
Manufacturer: Maeda Machinery Research Institute Ltd.
Model: MKC Type
Features
- Flow is visible at a glance
- This is a flow detector that checks the flow of fluid by the movement of a ball (or float) inside a transparent tube.
- The flow rate cannot be confirmed.
- Comes with a protective cover
- The metal protective cover reduces the possibility of damage due to external impacts.
- Installation orientation is not important Since a spring is used inside, the orientation when installing can be freely adjusted, such as upward, downward, or sideways.
