Working Principle

The liquid flows through the turbine meter in axial direction and causes the turbine wheel to rotate. A sensor measures the speed of the rotor (inductive blade or ferromagnetic pin pulse detection), which is proportional to the average flow velocity.

Applications

• crude oil, mineral oil, refined oil products (gasoline, kerosene, jet A1, JP8, diesel)
  
• liquefied gases
  
• acids, alkaline solutions, solvents, vinyl chloride
