Compact design plastic flowmeter

KOBOLD, represented locally by Instrotech , has on offer to industry their Model VKP flowmeter that works on the Variable Area principle, still one of the most-used measurement principles in flow engineering. Instead of the conical meas- uring pipe generally used, a conical mandril is placed inside a housing made out of robust, impact resistant polysulfone, on which there is a float with a sharp-edged orifice. The incoming medium flows through the float’s orifice and lifts it up against the power of a stainless steel spring onto the flow depending height. The actual flow rate can directly be read off a scale affixed to the outside of the housing. With the combination of spring and conical mandril this series of meters is far more compact than other commonly used devices with a conical measuring pipe. They are therefore ideal for measuring flow rates in ma- chines and aggregates. Enquiries: Tel: +27 (0) 10 595 1831 or email sales@instrotech.co.za
