Maeda Koki MKCM Water Signal – Flow Switch & Indicator

Maeda Koki MKCM Water Signal is a dual-function industrial instrument that combines the utility of a visual flow indicator with the safety of an electrical flow switch. Designed for critical fluid management systems, this device allows operators to visually confirm flow presence through a transparent window while simultaneously sending an electrical signal to control systems or alarms.

Description

In complex industrial machinery, simply knowing that fluid is present is often not enough; systems require automated confirmation that flow is active. The Maeda Koki MKCM Water Signal addresses this need by integrating a “rheoscope” (visual indicator) with a reliable flow detection switch.

Visual and Electrical Monitoring The core advantage of the MKCM type is its ability to provide two forms of verification. Visually, maintenance personnel can inspect the movement of the internal float through the transparent body to confirm fluid movement at a glance. Electrically, the unit detects fluid flow and triggers an ON or OFF signal based on the designated flow quantity. This allows the device to act as an interlock, preventing equipment from running if coolant or water flow is insufficient.

Robust and Universal Design Unlike fragile glass indicators, this unit is housed within a metal protective cover, significantly reducing the possibility of damage caused by accidental impacts or flying debris in a factory setting. Furthermore, the internal construction utilizes a spring mechanism rather than relying solely on gravity. This engineering choice ensures that the installation direction does not matter. Whether the pipe runs up, down, or sideways, the MKCM Water Signal functions accurately, providing engineers with maximum freedom during system layout design.
