Meanwhile Ledebuhr Industries says that its AccuStaltic multi-channel peristaltic pumps are ideal for metering. Tese pumps are truly positive displacement pumps and are very easy to use for precise metering of liquids, says the company. Controlling the rotation controls the flow. Measuring the rotation determines the exact amount of fluid delivered. AccuStaltic multi-channel pumps can pump liquids at adjustable flow rates and are very precise when averaged over time. Tey deliver a constant flow regardless of variations in back pressure. Tis feature, combined with the multi-channel design, makes them ideal for delivering the exact same amount of fluid to several points on different length feed hoses. Te pumps achieve not only precise metering, but also accurate flow dividing.
Subsea sampling
Established in 2009, the aim of Norwegian company Mirmorax is to become the industry’s leading provider of subsea sampling systems in the oil and gas industry. To this end the company has developed its award-winning Mirmorax subsea process sampling system (SPSS). Te SPSS delivers true volumetric sampling on oil, gas and water in the well without interrupting production. Te result is the ability to accurately capture
fluid properties throughout the lifetime of the field, conduct comprehensive pressure, volume, and temperature (PVT) analysis, calibrate multiphase and wet gas meters to ensure that they operate at their full potential, and deliver increased oil and gas recovery from the reservoir. It is based on a patented technology that ensures
true volumetric representation of each phase, independent of the content in the flow. Tis has a significant value for the operator, not only for multiphase or wet gas representation, but also for analysis of other chemicals or substances in the flow, such as hydrogen sulphide and salinity. Te system design is based on standard engineering principles and is a combination of innovation and field proven technologies, such as the pneumatic actuators, pre- qualified OEM ball valves and system for testing pressure integrity. Mirmorax supplies different subsea and topside
versions of the multiphase sampling system, from a manually operated system with a single sampling bottle to automated systems with a multi-bottle system integrated into a ROV-retrievable module, skid or container.
Te sampling system extracts and transports the sample into sampling bottles under isobaric conditions. ●
