Maeda Koki MKT Type OIL SIGNAL – Flow Gauge – Visual Flow Indicator

Maeda Koki MKT type OIL SIGNAL-Flow Gauge is a precision instrument designed for the visual monitoring of fluid flow in industrial piping systems. Engineered for clarity and versatility, this unit allows operators to confirm approximate flow quantities instantly through its transparent body. Its robust internal spring mechanism ensures functionality regardless of orientation, making it an ideal choice for complex machine layouts where installation space is limited.

Description

Reliable flow monitoring is critical for the safety and efficiency of hydraulic and lubrication systems. The Maeda Koki MKT type OIL SIGNAL-Flow Gauge provides a simple, durable, and effective solution for verifying flow rates at a glance.

This device operates using a transparent tapered pipe system. Inside the unit, a float or ball moves in response to the fluid pressure. By observing the position of this float relative to the distinct red indication lines marked on the body, maintenance personnel can determine the approximate flow quantity without the need for complex digital readouts. This direct visual confirmation helps in the early detection of blockages or pump failures.

A standout advantage of the MKT series is its installation flexibility. Unlike gravity-dependent flow sights that must be installed vertically, this unit incorporates an internal spring mechanism. This design allows the gauge to function correctly whether installed looking up, looking down, or facing sideways. This universal mounting capability simplifies piping design and retrofitting in tight industrial spaces.

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

  • Industrial Lubrication Systems: Monitoring oil flow to bearings, gears, and sliding surfaces.
  • Hydraulic Circuits: Verifying pilot flow or drain line circulation.
  • Machine Tooling: Ensuring coolant or cutting oil delivery.
  • General Piping: Visual check for fluid presence in various oil transfer lines.
