Automatic sampling for fiscal metering
For custody transfer measurement you need Custody Transfer Crude Oil Sampling Systems, these automatic sampling systems are used to accurately determine the quality of the custody transfer (crude) oil samples. Crude oil sampling systems are used to collect representative samples on custody transfer to be analyzed in a laboratory.
Custody transfer sampling allows the quality e.g. water and sediment content of a crude oil pipeline transfer to be established. This together with the metered quantity is used to calculate the product volume for commercial and fiscal transactions. The automatic custody transfer sampling is used in crude oil applications, which commonly contain crude, water and sediment.
Custody Transfer Crude Oil Sampling Systems are designed conform the Standard Practice for Automatic Sampling of Petroleum and Petroleum Products API 8.2, ASTM D.4177 and ISO-3171 standards with an automatic sampler probe, sample receivers, PLC controller.
The Automatic Probe sampler is the basic and most important integral part of the automatic inline probe sampling systems, it is a heavy duty reliable and accurate sample extraction device, which is designed to be mounted directly on the main pipeline and takes continiously grab crude oil samples of 1 ml volume, the sampler is actuated by a solenoid valve which is driven by a controller, generating either a flow proportional or time based signal, depending on the process. The Automatic Probe sampler is an integral part of the inline probe sampling systems.
Sample receivers, samples collected with the automatic fast-loop or in-line samplers are transferred to a sample receiver for storage.
Representative Custody Transfer Crude Oil Sampling Systems
The big advantage of crude oil custody transfer systems conform API 8.2 is the possibility to take a flow proportional or time based sample. With automatic grab sampling you get an average sample in the sample receivers from a whole blend or pipeline transfer to calculate the product volume for commercial and fiscal transactions. We have improved our automatic sampling systems for crude oil liquids by:
- Creating closed loop systems emission free which provide a safe, controlled environment
- Suitable for high pressure process application
- In-the-line or fast-loop samplers
- Fixed or variable volume receivers
- Simplifying designs, making the sampling of liquid and gas more efficient
- Proper discharge of excess liquid or gas prevents unwanted pressure build-up in the system
These modern solutions simply regard the sampling systems themselves. Our worldwide reputation rests on the combination of excellent systems, and professional services by our team of specialists.
