Pipeline fluid flow rate measures the volume of product transported per unit time — typically expressed in m³/h, barrels per day (bpd), or standard cubic feet per day (scf/d).

Pipeline fluid flow rate measures the volume of product transported per unit time — typically expressed in m³/h, barrels per day (bpd), or standard cubic feet per day (scf/d). Flow rate is a fundamental operating parameter that influences pipeline pressure, temperature profile, erosion risk, and inspection feasibility.

Flow rate directly impacts pipeline inspection planning: inline inspection (ILI) tools require minimum flow velocities to operate, and insufficient flow is one of the most common reasons a pipeline becomes unpiggable. Low-flow or intermittent-flow pipelines often cannot support smart pig runs.

For pipelines with flow constraints, EMPIT’s aboveground Current Magnetometry Inspection (CMI) provides a flow-independent alternative. CMI inspects pipeline condition from the surface regardless of internal flow conditions — making it the ideal inspection solution for low-flow, shut-in, or unpiggable pipelines.
