Maeda Koki MKC type AIR SIGNAL – Flow Indicator with Valve

Maeda Koki MKC type AIR SIGNAL – Flow Indicator is a robust and versatile solution designed for the precise monitoring and regulation of gas flow in industrial systems. Combining a clear visual display with a built-in control mechanism, this unit allows operators to instantly verify flow status through a transparent taper pipe. Its durable construction and flexible installation options make it an essential component for maintaining efficiency in pneumatic and gas distribution lines.

Description

Maeda Koki MKC type AIR SIGNAL – Flow Indicator is engineered to provide immediate visual feedback and control over air and gas lines. It operates on a variable area principle, utilizing a transparent taper pipe housing a float ball. As the flow rate changes, the ball moves relative to a distinct red indication line, enabling the user to confirm the approximate flow quantity simply by viewing the device.

Unlike standard indicators, this unit features an integrated miniature adjustment valve. This allows the operator to manually set the necessary flow quantity by aligning the float ball with the indication line, ensuring the system operates within its required parameters. To withstand the rigors of industrial environments, the glass components are shielded by a sturdy metal protective cover, significantly reducing the possibility of damage from external shocks or impact. Furthermore, the internal spring mechanism eliminates gravity dependence, allowing for universal installation—whether facing up, down, or sideways—without compromising accuracy.

Features

  • It can see a flow at first sight
    It is a rheoscope confirming fluid flow by the movement of transparent balls (or afloat) in the jurisdiction. It cannot confirm the flow quantity.
  • With protective cover
    By a metal protective cover, It reduces the possibility of damage by shocks from the outside.
  • The installation direction does not matter
    Because It uses a spring inside, the posture when I attach it looks up and looks down and can perform sideways-facing freely.

Applications

MKT is a flow indicator, flow switch, and flow control depending on the type. It can confirm the flow of the water by viewing the movement of the ball. With a protective cover, when you want to confirm approximate flow quality, please choose the MKCT type
