KOBOLD KFF/KFG flow meters are used for sensing small, to extremely small, volumetric flow rates of gases (KFG) and liquids (KFF). The media must be transmissive for infrared light.
KFF-1/ KFG-1 flow meters are available in Ryton®, brass and PTFE materials; therefore suited for many applications in industry, in laboratories, and so forth. The new KFF-15 sen- sor is delivered as standard with (0 - 5 VDC) analogue output and frequency output. The frequency output is optional on the KFF-10 / KFF-11 models.
Series KFF-3 / KFG-3 flow meters are available in Ryton® and in brass.
Function Principle
The flow meter 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 photo- diodes. The flow rate is output as a frequency signal or a linear analogue (0 - 5 VDC).
