The Flexim FLUXUS F631 BA is ready for measurement in just five minutes and is the portable clamp-on flow meter of choice for servicing and maintenance activities, as well as for controlling and auditing measurement points not covered by permanent meters, or for the temporary replacement of permanently installed flow meters.
With its Li-ion battery, the F631 enables up to 24 hours of autonomous operation.
Matched and paired transducers, together with sophisticated algorithms that detect pipe wall echoes and incorrect transducer positioning, ensure reliable and highly accurate measurements - even under demanding application conditions.
With the FLUXUS 631 family, Emerson also offers portable flow and energy meters for gases, liquids, and steam.
