Maeda Koki MKCTV type AIR SIGNAL – Adjustable Flow Indicator

Maeda Koki MKCTV type AIR SIGNAL – Flow Indicator is a versatile and robust solution designed for the visual monitoring and regulation of gas flow. This unit combines the functionality of a flow meter with a control valve, allowing operators to easily verify flow quantities through a clear, tapered glass tube. Engineered for flexibility, its internal spring mechanism supports installation in any orientation, making it a reliable choice for complex industrial piping systems.

Description

MKCTV type AIR SIGNAL is engineered to provide immediate visual feedback on gas flow status within your pneumatic or industrial systems. It operates on a variable area principle using a transparent taper pipe and a floating ball. As the medium flows through the device, the ball rises; when it aligns with the distinct red indication line, the operator can confirm that the approximate necessary flow quantity has been reached.

Unlike standard flow indicators that are often fragile or strictly gravity-dependent, this unit is built for durability and adaptability. It features a built-in miniature adjustment valve, which allows for precise setting of the flow rate directly at the point of observation. By adjusting the valve until the ball meets the red line, users can ensure consistent system performance. Furthermore, the unit is encased in a sturdy metal protective cover, significantly reducing the risk of damage from external shocks or accidental impacts in busy facility environments.

Features

  • Visual Flow Confirmation Utilizes a transparent taper pipe with a high-visibility red indication line and a float ball, allowing for quick checks of approximate flow quantity.
  • Integrated Adjustment Valve Equipped with a miniature valve that enables the operator to fine-tune the flow rate, ensuring the float ball aligns perfectly with the indication line for the required setting.
  • Omnidirectional Installation Designed with an internal spring mechanism that eliminates gravity dependence. This allows the unit to be mounted upwards, downwards, or sideways without affecting performance.
  • Robust Construction Features a metal protective cover that shields the glass components from external physical shocks and impact damage.

Applications

Maeda Koki MKCTV type AIR SIGNAL – Flow Indicator is suitable for a wide range of industrial applications requiring gas flow management, including:

  • Compressed air lines in manufacturing plants.
  • Gas supply monitoring for industrial furnaces and burners.
  • Pneumatic control systems.
  • Cooling air circuits for machinery.
  • Laboratory gas distribution systems where visual verification is required.
