Application:
Turbine flow meters are widely used in petroleum ,chemical, metallurgy, organic liquid, inorganic liquid,
liquefied gas, urban gas pipe network, pharmacy, food, paper-making industry etc .Turbine flow meter is
used to measure low viscosity, non-corrosive, clean liquid volume and cumulative flow rate in closed pipeline.
Product features
High accuracy generally up to + / – 1% plus or minus 0.5% high precision type can reach 0.2%
Repeatability is good the short-term repeatability could reach 0.005% to 0.005%
Total output pulse frequency signal and is suitable for metering and connected to the computer no zero drift strong anti-jamming capability
Strong signal resolution
