Maeda Koki MKCM Type OIL SIGNAL – Flow Indicator with Switch

Upgrade your system’s intelligence with the Maeda Koki MKCM type OIL SIGNAL – Flow Indicator, a dual-function device that combines visual monitoring with automated signaling. This advanced unit not only allows operators to see the flow at first sight but also features an integrated switch that detects fluid flow status. Protected by a heavy-duty metal cover, it is built to withstand external shocks while providing critical data to your control systems.

Description

Maeda Koki MKCM Type represents the next level of lubrication management, moving beyond simple visual checks to active system integration. While it retains the core rheoscope function of the standard models—allowing you to confirm fluid flow by the movement of transparent floats inside the housing—its primary advantage lies in its electrical capability.

This unit is equipped with a flow detection switch. It automatically detects the presence of fluid flow and toggles the switch status (ON/OFF) based on the designated flow quantity. This feature is vital for automated machinery, allowing the system to trigger an alarm or emergency stop if lubrication flow fails. It is important to note that the switch set point is rigid and fixed; the set point cannot be changed or traced manually, ensuring tamper-proof reliability.

Durability is also a key focus of the MKCM design. It is encased in a metal protective cover, significantly reducing the possibility of damage caused by physical shocks or accidental impacts from the outside. Despite this robust armor and added functionality, it retains the series’ signature flexibility: the internal spring mechanism ensures that the installation direction does not matter. You can mount it looking up, looking down, or sideways freely without affecting the switch or visual performance.

Features

  • A switch is with flow quantity
    It detect fluid flow and let it is ON, or a switch be 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
    By a metal protective cover possibility of the damage by shocks from the outside
    I reduce it.
  • The installation direction does not matter
    The posture when I attach it as I use a spring inside
    I look up and look down and can perform sideways-facing freely.

Applications

MKCM oil signal is a flow indicator, flow switch, and flow control depending on the type. Flow Switch with the point of contact function. It is equipped with a protective cover superior in reliable durability in a severe environment. It is low-priced with a simple structure. A simple flow Switch.
