The CFS is a highly dynamic flow sensor for liquids. It is based on the proven differential pressure technology of ReseaTech, but impresses with its compact design and easy integration.
The CFS differential pressure flow sensor was designed for measuring dynamic dosing processes. It is well suited for monitoring peristaltic pumps, syringe pumps and dosing valves. In contrast to the Pulsed Flow Sensor, however, the CFS is not suitable for measuring sub-microlitre drops and does not have the triggered high-resolution measuring modes of the PFS-Controller. Thanks to its good dynamics, however, drops of 20 microliters and more can still be detected and measured. The fast, continuous sampling rate means that even short events such as a pulse or an air bubble cannot be overlooked during measurement. The CFS constantly records the flow rate at 100 Hz, regardless of how high the readout interval is set. This can be from 0.01 to 100 seconds.
