Variable area flow-meter Orange Research

Our variable-area flowmeters are designed for liquid or gas applications where rotameters often fall short. These models have large dials with bold markings and
characters that are easy to read from a distance. They also handle high line pressures and can be mounted in any orientation.
Like rotameters, they are mounted directly in the flow stream, but with bodies machined from solid blocks of metal, they handle high-pressure applications of up to 5000 psi (vs 150 psi for rotameters). This makes them a natural for hydraulic systems.
