Cignus Instruments AS is industrializing a novel and patented concept for precision direct mass-flow measurements of gases and liquids with particular advantage for applications within the emerging H2 and CCS value chains. Our technology is developed in close partnership with major energy companies, pipeline operators and equipment suppliers with global ambitions and motivated by the green transition.
Key benefits of the Cignus Mass Flowmeters
- High accuracy at large pipe sizes and thick walls.
- High accuracy at high operational pressures and for low density fluids like gases.
- Very low pressure loss.
- One flowmeter scalable to very large sizes removing the need for several small flowmeters on the same line.
- Submerged and Subsea adaptable design.
