KFF/KFG - Low Volume, Rotating Vane Flow Meters

Brand: KOBOLD Instruments, Inc

KOBOLD KFF/KFG flow meters can measure very low flow rates. They are suitable for a wide variety of industrial, commercial and laboratory flow applications involving media transparent to the near-infrared spectrum. 

The flow sensor uses a pelton-type turbine wheel and photodiodes to generate an electrical signal linearly proportional to flow rate. 

This output signal (accessible via the included cable) can be either a pulse or 0–5 VDC analog output usable with a variety of data acquisition equipment. 

These sensors are available in PPS or brass construction for applicability to a wide variety of process situations.
