Maeda Koki MKCM type AIR SIGNAL- Flow Indicator it is a rheoscope confirming fluid flow by the movement of transparent floats in the jurisdiction, detect fluid flow and let it is ON, or a switch be off with the flow quantity of the designation. It is a rheoscope confirming fluid flow by the movement of transparent floats in the jurisdiction.

With a metal protective cover possibility of damage by shocks from the outside, The posture when I attach it as I use a spring inside looks up and looks down and can perform sideways-facing freely.

Features

A switch is with flow quantity. It detects fluid flow and lets it is ON, or a switch is off with the flow quantity of the designation. ※The switch is rigid (the setpoint change from a trace is not possible)
It can see a flow at first sight. It is a rheoscope confirming fluid flow by the movement of transparent floats in the jurisdiction
With protective cover. With a metal protective cover possibility of the damage by shocks from the outside, It reduces it.
The installation direction does not matter. The posture when It attaches it as It uses a spring inside. It looks up and look down and can perform sideways-facing freely.

Applications

MKT is a flow indicator, flow switch, and flow control depending on the type. It is the electric point of contact model rheoscope using the lead switch. With protective cover. It can appoint the operation flow quantity of the switch
