Maeda Koki MKTV type AIR SIGNAL – Omni-Directional Gas Flow Indicator

Gain complete control over your gas lines with the Maeda Koki MKTV type AIR SIGNAL, a versatile flow indicator designed for challenging installation environments. Unlike standard rotameters that rely solely on gravity, this device utilizes an internal spring mechanism, allowing it to be mounted in any orientation—vertical, horizontal, or even upside down—without compromising accuracy.

Description

In complex piping layouts, finding a vertical run for a standard flow meter can be difficult. The Maeda Koki MKTV type AIR SIGNAL solves this engineering headache by offering true installation flexibility. By incorporating a spring inside the transparent taper pipe, the device maintains the float’s position relative to the flow force regardless of gravity. This means you can perform sideways-facing or inverted installations freely, adapting the component to your machine’s design rather than forcing a design change.

Visual Verification and Adjustment The unit is designed for immediate visual feedback. It features a transparent taper pipe housing a ball (or float) and a distinct red indication line. Operators can confirm the approximate flow quantity simply by looking at the position of the ball relative to this line. If the flow deviates from the target, the integrated miniature valve allows for immediate correction. By adjusting the valve, you can align the ball with the red indication line, effectively setting the necessary flow quantity with precision and ease.

Features

  • Omni-Directional Installation: The internal spring mechanism allows for mounting in any posture, including looking up, looking down, or sideways.
  • Visual Flow Monitoring: Uses a transparent taper pipe and a ball/float system for clear visibility of the flow status.
  • Integrated Adjustment Valve: Includes a miniature valve that allows users to regulate flow quantity directly at the indicator.
  • Reference Indication: Features a red indication line on the glass to serve as a visual set-point for the ball position.
  • Gas Application: Specifically designed for use with AIR SIGNAL gas applications.

V type AIR SIGNAL is ideal for pneumatic and gas control systems where space is limited or piping routes are complex. Common applications include:

  • Pneumatic Control Panels: Monitoring air supply to actuators and cylinders.
  • Gas Purge Lines: Ensuring consistent gas flow in analyzing equipment or protective enclosures.
  • Machine Tooling: Air sealing or cooling lines where installation space requires horizontal mounting.
