Product Introduction

The GT600B mass flowmeter is a high-precision mass flowmeter designed based on the Thermal Diffusion Principle. It directly measures the mass flow rate of gas using two platinum resistance temperature sensors, eliminating the need for separate temperature or pressure compensation. Offering high precision and a wide measuring range, it provides a reliable gas flow measurement solution in various industrial fields.

Product Features

  • Direct Mass Measurement: Mass flow rate or volume flow rate under standard conditions can be obtained instantly without temperature and pressure compensation.

  • Wide Turndown Ratio: Capable of measuring from minute flow velocities of 0.1 Nm/s up to high velocities of 120 Nm/s, making it highly effective for gas leak detection.

  • Excellent Durability: With no moving parts in the sensor, it features high resistance to vibration, easy maintenance, and a long lifespan.

  • Digital Interface: Equipped with a 4-line LCD display, real-time data can be clearly verified on-site, and integrated management is available via RS-485 communication.

Applications

  • Industrial Process Gases: Flow control of various process gases such as Oxygen (O2), Nitrogen (N2), Hydrogen (H2), Argon (Ar), Helium (He), and Carbon Dioxide (CO2).
  • Energy & Fuel Management: Flow measurement of Natural Gas (NG), LPG, Methane, and Propane, as well as combustion air flow optimization for boilers and furnaces.
  • Iron, Steel & Chemical Plants: Measurement of Blast Furnace Gas (BFG), Coke Oven Gas (COG), and Linze-Donawitz Converter Gas (LDG), along with Flare Gas monitoring.
  • Environment & Utilities: Leak detection in compressed air systems, oxygen control in wastewater treatment aeration tanks, and measurement of flue exhaust gas and mine ventilation systems.
