Going with the flow

Eureka magazine interviews Martin Hughes of PA Consulting Group on the new design of flow meter developed by PA that could halve production costs. December 2007

A new design of flow meter could be produced at half the cost of existing models, because it uses a different principle to measure fluid flow rate. Instead being able to rotate freely, the fanblade is driven by a small motor until it reaches the speed at which it takes no energy from the surrounding fluid.

This new design, developed at PA's Cambridge, UK, technology centre, delivers a huge increase in the range of flow rates that can be accurately measured –  the so-called 'turndown ratio' – so the new device could take the place of several conventional flow meters in a single application.

This also means that the flow meter cannot damage delicate fluids such as blood.
