Maeda Koki MKT Type Water Signal – Flow Indicator & Monitor

Ensure the reliability of your cooling and lubrication lines with the Maeda Koki MKT Type Water Signal – Flow Indicator. Designed for immediate visual verification, this robust device allows operators to check flow presence and approximate quantity at a glance. Its spring-loaded internal design offers exceptional versatility, allowing for installation in any orientation without compromising performance.

Description

Maeda Koki MKT Type Water Signal is a precision-engineered flow monitoring solution designed to bring clarity to your piping systems. Unlike standard sight glasses that only show the presence of liquid, the MKT type utilizes a specialized transparent tapered pipe housing a distinct ball or float mechanism. As fluid passes through the system, the internal spring interacts with the flow, positioning the float against a graduated indication red line. This simple yet effective design enables engineers and maintenance teams to confirm approximate flow quantities instantly without the need for complex digital instrumentation.

Flexibility is a core advantage of the MKT series. Traditional flow indicators often require strict horizontal or vertical mounting to function correctly due to gravity reliance. However, the Maeda Koki MKT type WATER SIGNAL – Flow Indicator integrates an internal spring mechanism that stabilizes the float. This engineering choice implies that the installation direction does not matter. Whether your piping layout requires the unit to look up, look down, or face sideways, the MKT performs consistently, making it an ideal choice for complex machinery and tight spaces where piping geometry varies.

Features

  • It shows flow quantity by viewing Because it use a transparent taper pipe, MKT can confirm approximate flow quantity by looking at a ball (or a float) and the position with the indication red line concerned.
  • The installation direction does not matter Because it use a spring inside, the posture when it 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 approximate flow quality of the water by viewing.
