Maeda Koki MKT type AIR SIGNAL Flow Indicator Omni-Directional

Ensure reliable monitoring of your pneumatic systems with the Maeda Koki MKT type AIR SIGNAL – Flow Indicator. Designed for versatility, this compact unit eliminates the installation constraints typical of gravity-dependent flow meters. Its internal spring mechanism allows it to function accurately in any orientation, making it the perfect solution for complex piping layouts.

Description

Maeda Koki MKT, Since this product is using the tube of taper form for a transparent tube, it can beused also as a flow rate viewing type of a short form by seeing the related position ofa ball and the indicating red line.

Since the spring is being used for this product in a transparent tube, the postureswhen attaching are freedom, such as facing up, facing down, and sideways.The heat resistant is 80 ℃.Standard pressure resistance : 1MPa

Features

  • 360-Degree Installation: Engineered with an internal spring that allows for vertical (up/down) or horizontal (sideways) mounting orientations.
  • Visual Status Check: Features a clear transparent taper pipe that allows operators to view the flow quantity directly.
  • Red Indication Line: Includes a visual reference mark on the sight glass to assist in confirming the ball/float position.
  • Gas Application: Specifically designed for use in gas and air piping systems (AIR SIGNAL series).
  • Compact Design: Streamlined form factor suitable for in-line integration.

Applications

  • Maeda Koki MKT type AIR SIGNAL – Flow Indicator is an essential component for any facility relying on compressed air or gas distribution. It is particularly useful in:
  • Complex Piping Networks: Where vertical runs are unavailable for standard flow meters.
  • Pneumatic Machinery: Verifying air supply presence to critical components.
  • Gas Purge Systems: Visual confirmation of flow in horizontal branch lines.
  • General Automation: Simple, non-electric flow monitoring for maintenance checks.
