Description
The KROHNE OPTIMASS 6000 is a high-performance twin-tube Coriolis mass flowmeter for liquids, gases and slurries, from size 08 up to 250. It achieves ±0.1% of rate for liquids (±0.05% option) and better than 0.35% for gases, and measures density from 100 to 3,000 kg/m³.
Versions cover cryogenic service down to −200 °C, standard duty to +230 °C and high temperature to +400 °C, with 316L, duplex or Hastelloy C22 tubes rated up to 200 barg. It holds MID and OIML custody transfer approvals and SIL 2/3 capability.
