Kobold KFF-1000 ranges from 15 to 5000 ml/min, and KFF-1009 range is 1-10L ml/min.

KOBOLD KFF/KFG Series turbine flow sensors and flowmeters 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 low volume 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. KFF/KFG Series low volume turbine flow sensors and flowmeters are available in Ryton®, brass or PTFE (Teflon®) construction for use in a wide variety of process situations. Our PTFE flow sensors and flowmeters come standard with both analog (0-5 VDC) and frequency outputs. The frequency output on other models is optional. If price is a key issue, the standard PTFE/Kalrez® fittings on KFF/KFG-1500 Series pelton wheel flow sensors can be replaced with PVDF (a.k.a. Kynar®)/Viton® for a slight cost reduction. Contact your factory representative for details.
