Flow Measurement

Benefits of a TRACERCO Diagnostics™ Flow Study

• Investigation of flow distributions in networks
• Determine leakage past relief valves or block valves
• Perform mass/flow relationships through flare lines or piping systems
• Measure flows where flow meters do not exist

TRACERCO Diagnostics™ Flow study technology is used to measure flow velocity in piping systems by injecting a tracer material into the line and placing sensitive detection devices externally on the piping to monitor the tracer's position and movement. The measured flow velocity combined with the pipe cross-sectional area allows the computation of the volumetric flow rate at line conditions. Suitable tracers are available for flowing gases, aqueous and organic liquids and solids.

Two techniques have been found to be particularly applicable to measuring flows in process plants, the "pulse velocity" and "dilution" techniques. A Tracerco engineer will study the process system to determine the most suitable injection and sample points so that the appropriate technique is used to provide the best results.

Flow rate measurements through sections of the piping system are performed in strategic locations to detect and isolate the sources of fugitive flow, calibrate existing flow meters, measure flow rates where no meters exist, and investigate the flow distribution through piping networks such as utility headers.
