*Specifications are subject to change without prior notice.

The Coriolis mass flowmeter MASSMAX® 3400 series consists of the single Z-shaped measuring tube which is well-accepted as very small flow measurement, and newly-developed high performance converter MMC400.
The epoch-making sensing technologies have achieved the accurate flow measurement of very small flow rate with a wide rangeability.
Stainless steel 316L as standard and Hastelloy® C22 as an option are used for the wetted parts of the flowmeter. With 3 sizes of 1, 3 and 4mm MASSMAX® 3400 is suitable for the accurate measurement of very small flow rate as low as 1 kg/h or less.
