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.
