Level, Switching and Pressure Measurement on the Pipeline
The pipeline is truly the lifeline of a refinery. Crude oil is transported to the refinery via pipeline, either from an oil terminal or directly from the oil wells. Pipelines also serve as a means of conveyance for various oil distillation products.
Where pig valves or slide valve stations are located, concrete impounding basins serve to protect the environment from possible leakages of the shut-off devices.
Pressure Monitoring in the Pipeline with VEGABAR 52
Pressure transmitters are usually connected to a pipeline via impulse piping. The VEGABAR 52 pressure transmitter is especially well suited for this application. The mechanical construction of the sensor and its high overload resistance guarantee a reliable measurement of pressure conditions.
Reliable Level Switching Independent of Product
The VEGASWING 63 vibrating level switch is ideal for detecting levels in the impounding basin. It delivers a dependable level signal that is completely product independent. As an added benefit, the sensor complies with the requirements of SIL 2 for implementation in safety-critical applications.
Accurate Level Signal with the VEGAPULS 62
The VEGAPULS 62 radar sensor lends itself well to continuous level measurement for leakage monitoring. Due to its small dimensions and powerful signal focusing, the device can be mounted very close to the vessel wall. The non-contacting measuring principle operates independent of weather conditions and is completely maintenance-free. The continuous level signal can also be used to generate multiple level switching points in the superordinate control system.
Interface Measurement with the VEGAFLEX 67
Rain or ground water often penetrates into the impounding basin. To detect how much oil and how much water is in the basin, the VEGAFLEX 67 guided wave radar is applied. It can measure the thickness of the oil layer as well as the total level in the basin. With this information, it provides the basis for deciding whether or not the facility poses a danger to the environment.
