KOBOLD KFF/KFG flowmeters are used for measuring low and smaller, volumetric flow rates of gases (KFG) and liquids (KFF). The media must be transmissive for infrared light.

Series KFF/KFG 1000 flowmeters are available in Ryton®, brass and PTFE materials; therefore suitable for many applications in industry, in laboratories, and so forth. The new PTFE sensor of the 1000 series is delivered as standard with (0 ... 5 VDC) analogue output and frequency output. The frequency output is optional on other models.

Series KFF/KFG 3000 flowmeters are available in Ryton® and in brass.

Function Principle
The flowmeter is based on the Pelton Principle, that is, the flowing medium causes a vane to rotate. The rotary motion is converted to electrical impulses by means of photodiodes. The flow rate is output as a frequency signal or a linear analogue (0...5 VDC).
