One of the most important applications for flow measurement is custody transfer. There are many different meters used in custody transfers and in particularly positive displacement flow meters are highly regarded as a standard.
Using a positive displacement meter in custody transfers are highly accurate in the transfer of commercial and industrial water, as well as natural gas and other liquids. PD meters also are great for measuring low flows and high viscous flows. Another great reason for using a PD meter in custody transfers is that they capture the flow in a container known as volume, making speed of flow a non issue.
Other meters used in custody transfers are:
Differential Pressure Flow Meters
Turbine Flow Meters
Coriolis Flow Meters
Ultrasonic Flow Meters
Positive Displacement Flow Meters
