KOBOLD plastic flow meters 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 bistable switches. The use of the high-quality material PVDF (model KSK 3...) means that this type is very suited for service with corrosive media.
