Review the complete description, feature set, and specification details before sending your inquiry.

The HTR Metal Tube Rotameter is a robust industrial flow measurement solution designed for precise monitoring of liquid and gas flow in critical environments. Widely used across oil & gas, water treatment facilities, chemical processing plants, HVAC systems, marine applications, and vehicle-based fluid systems, this device ensures consistent and reliable flow control in demanding operational conditions.

Key Features

  • High durability metal construction for long service life
  • Suitable for both liquid and gas flow measurement
  • Wide measurement range supporting industrial scalability
  • Stable output signal with process control compatibility
  • Designed for harsh environmental and pressure conditions

Design & Functionality

The device operates on a variable area principle where the float position changes with flow rate, providing accurate and continuous measurement. Its metal tube construction enhances resistance to pressure, corrosion, and temperature fluctuations, making it ideal for industrial process environments.

Total Crossed Beams

Engineered for structural integrity, the internal design supports stable float movement and minimizes turbulence. This ensures accurate readings even in fluctuating flow conditions common in industrial systems.

Beam Pitch Options

The optimized internal geometry allows smooth flow passage with minimal obstruction. This improves measurement consistency across different fluid types including viscous liquids and compressed gases.

Intrinsic Synchronism

The rotameter maintains synchronized response between flow rate and float position, enabling real-time monitoring. This is critical for automated process control systems requiring reliable data output.

Operational Advantages

  • Ideal for oil & gas pipelines and refining systems
  • Effective in water and wastewater treatment plants
  • Reliable for chemical dosing and process industries
  • Supports HVAC systems for airflow and liquid monitoring
  • Suitable for marine and vehicle-based fluid systems
  • Enhances process control accuracy and efficiency
