Maeda koki MK Water, oil, air signal flow indicator

MK Type can confirm a flow of the water, oil, and air by viewing by the movement of the ball. It is a rheoscope confirming fluid flow by the movement of transparent balls (or afloat) in the jurisdiction. It cannot confirm the flow quantity. The posture when attaching it as using a spring inside looks up and looks down and I can perform sideways-facing freely.
