ABB Variable area flowmeters

Product Description

Variable area flowmeters are the most cost effective solution for almost all applications involving the measurement of industrial process liquids, gases or steam. ABB´s variable area flowmeters are reliable, flexible and simple. They meet the application requirements by featuring a wide range of design varieties and sizes. Technology proven, they offer a long life and high reproducibility. Variable area flowmeters are excellent mechanical back-up meters because no external power supply is needed.

Commonly called “Rotameters”, or “Purgemeters”, ABB has many to choose from depending on fluid being measured, accuracy requirements, and hazards.
