  • Positive Displacement Flow Meters - Fuel Flow Measurement

    Positive displacement type flowmeters usually offer high accuracy i.e. about ±0.1% of actual flow rate sometimes. The metering accuracy of the unit gets better with the increase in the process fluid viscosity. PD meters also provide excellent repeatability which can be as high as 0.05% of reading. PD meters can work without using a power supply.
