Flow assembly for multi-parameter measurements Flowfit CYA27

Flowfit CYA27 allows for monitoring of up to 6 relevant parameters at the same time. Sensors installed in the assembly need a sample flow as low as 5 l/h (1.32 gph) for accurate measurement. This enables precise control of processes such as disinfection with minimum water loss. The assembly offers flexible mounting options, an integrated sampling valve and a cleaning and dosing module. A flow monitoring can ensure that your measurement is always operational.
