Leak Detecting Equipment

Time to Read: 1m 55s

The term “leak detecting equipment” refers to any of a number of devices used to find leaks in pressure vessels, pipelines, and other pressurized storage and/or transportation containers. This equipment can be used in systems that contain fluids or gases. In general, there are two types of leak detecting equipment: internally based and externally based.

Internally Based Equipment

Internally based leak detecting equipment uses field instrumentation to monitor internal system parameters such as flow, pressure, and fluid temperature. Fluctuations in monitored parameters can be used to identify and locate a leak in the system. Local monitoring of pressure or flow provides simple leak detection requiring no telemetry, but is only useful in steady-state conditions and is limited in its ability to detect changes in gas systems. Additionally, this method requires a relatively long
