  • (non-)conductive liquids, gases, saturated and superheated steam

  • Gross/net heat metering of steam and hot water

  • Monitoring of compressor output and evaluation of Free Air Delivery (FAD)

  •  Industrial gases (natural gas, nitrogen etc.)

  •  Compressed air systems

  • Thermal oils,Desalinated water etc.

Breif introduction

LUGB vortex flow meters are widely used in the measurement and control of superheated steam, saturated steam, compressed air and general gases (oxygen, nitrogen, hydrogen, natural gas, gas, etc.), water and liquids (such as water, gasoline, alcohol, benzene, etc.) in petroleum, chemical, metallurgy, heat, textile, paper and other industries.



1. Simple structure,  no moving parts, high reliability

2. High accuracy 1.0%, 1.5%

3. Wide measuring range, up to 1:10 ratio

4. Resist high temperature up to 350℃,normal temperature up to 250℃

5. Integral forging, anti-rust, long service life

6,Less pressure loss, lower operating costs, more energy-saving significance.
