SITRANS F R rotary piston flow meters from Siemens are bestsellers. The benefits offered by their conventional mechanical measuring technique include reliability, precision and a robust design for measuring aggressive media and high-viscosity fluids. Viscosities ranging from less than one mPa.s to 350,000 mPa.s are no problem for the reliable rotary-piston meter

Rotary piston flow meter application examples: Petroleum industry, Raw material industry
