Kobold KSK Variable Area Flow Meter Plastic

Overview

Kobold KSK Variable Area Flow Meter Plastic 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.

Kobold KSK Special Advantages
