KSK Kobold Variable Area Flowmeter-Plastic

KOBOLD plastic flowmeters and switches model KSK are based on the well-known suspended float principle. They are used for measuring and monitoring flows in closed pipes. The media flows, from below, through a conical plastic measuring tube. This raises the float and the flow rate can be read off against the scale. The instruments can be fitted with bi-stable switches.
