CMR has a long-standing tradition of developing measurement methods and equipment for the characterisation of fluid properties. Application areas range from Oil&Gas and aquaculture to environmental monitoring.
CMR has developed a large variety of methods for characterising single- as well as multiphase fluids, based on acoustic, electromagnetic, gamma-ray, or optical sensors. Amongst others, the following properties can be used to characterise different fluids:
- Density and permittivity of crude oil
- Caloric value of hydrocarbon gas
- Water salinity and salt composition
- Water-to-liquid ratio
- Dissolved carbon dioxide in water
These parameters might be used directly, or integrated into multimodal measurement systems. Along these lines, CMR has developed the Subsea Online Fluid Analyser (SOFA), a multimodal, in situ, in-line measurement system for multiphase hydrocarbon streams. The core idea of SOFA is to sample the fluid by diverting a small portion of it into an in-line separation chamber. Here, measurements are performed on the individual phases using acoustic, gamma-ray, and electromagnetic sensors, before the fluid sample is released back into the stream.
