Flexim Fluxus F601 Portable Flowmeter

The Flexim Fluxus F601 Portable Flowmeter is the portable thermal energy 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 flowmeters. This flowmeter has a temperature monitoring range of -40 to 392°F, is measurement ready in less than 5 minutes, and is designed to easily withstand rough industrial environments.

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. Due to the new HybridTrek mode, the portable flowmeter can also reliably and accurately measure liquid flow under conditions with a high fraction of solid particles or gaseous loads.

ATEC also offers the Flexim FLUXUS G601 Flowmeter option.
