Datasheet

The Flexim Fluxus F601 Portable Flowmeter is the portable clamp-on flow meter of choice for servicing and maintenance activities, the control and auditing of measurement points not covered by permanent meters, or even the temporary replacement of permanently installed flow meters. The Flexim Fluxus F601 is measurement ready in less than 5 minutes, including the measurement of the pipe wall thickness, the connection of the transducers to the transmitter, the parameterization of the flow meter and finally the mounting of the transducers.

The Flexim Fluxus F601 was designed to easily withstand rough industrial environments while featuring an ergonomic design, which offers simple handling and maximum ease of use. Besides its sturdy housing, the Flexim Fluxus F601 features stable and precise latching transducer connectors and stainless steel armored cables to prevent damage during daily work. With its Li-Ion battery, the F601 allows for up to 14 hours of autonomous measurement. Matched and paired transducers as well as sophisticated algorithms correct for pipe wall echoes and wrong transducer positioning, thus ensuring reliable and highly accurate measurements - even under the most demanding application conditions. Due to the new HybridTrek mode, the portable flow meter can also reliably and accurately measure liquid flow under conditions with a high fraction of solid particles or gaseous loads.
