The 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.
FEATURES
• Large, easy-to-read dial • Rugged, high line pressure design • Vertical or horizontal mounting • 0-1 to 0-30 GPM (liquid) • 1.5-10 to 1-100 SCFM (gas)
