Maeda Koki MKCT Type Water Signal – Flow Indicator

Maeda Koki MKCT Type Water Signal – Flow Indicator is a robust visual monitoring instrument designed specifically for water applications. Unlike standard indicators, this model is equipped with a durable metal protective cover, significantly reducing the risk of damage from external shocks or impacts in harsh industrial environments. Its spring-loaded internal mechanism allows for versatile installation in any orientation, making it an ideal choice for complex piping systems where space and safety are paramount.

Description

Reliable fluid monitoring is essential for maintaining the efficiency of industrial water circuits. The Maeda Koki MKCT Type Water Signal – Flow Indicator provides engineers and maintenance teams with an immediate, clear visual confirmation of flow status and approximate quantity.

This device utilizes a transparent tapered pipe system housing a ball or float. As water flows through the unit, the internal component rises or moves, aligning with specific red indication lines marked on the body. This simple yet effective design allows operators to gauge flow volume at a glance without the need for electronic power or complex sensors.

A defining characteristic of the MKCT series is its rugged construction. Recognizing the hazards of busy plant floors, this unit features a metal protective cover that shields the transparent viewing area from accidental knocks and debris. Furthermore, the internal spring mechanism eliminates gravity dependence, allowing the unit to be installed looking up, looking down, or facing sideways. This flexibility simplifies the design of piping layouts and ensures accurate readings regardless of the installation angle.

Features

  • It shows flow quantity by viewing
    Because use a transparent taper pipe, with a ball (or afloat) and the indication red line
  • It can confirm approximate flow quantity by looking at the position concerned.
  • With protective cover
    By a metal protective cover, I reduce the possibility of damage by shocks from the outside.
  • The installation direction does not matter
    Because use a spring inside, the posture when attach it looks up and look down; and It can perform sideways-facing freely.

Applications

  • Industrial cooling water circuits.
  • Water drain line monitoring.
  • General water piping systems require visual flow confirmation.
  • Machinery with exposed piping where impact protection is necessary.
