Orange Research’s fully integrated differential-pressure (DP) flowmeters are compact and rugged with directly connected, large-throated, non-clogging flow nozzles. The product line features low-pressure-drop flow nozzles; 3.5-inch dials; 1/2-inch to 2-inch NPT porting; and a choice of brass, stainless steel, or aluminum bodies suitable for a range of applications. The flow nozzle is a long-life, wear-resistant design with a rounded leading face that reduces turbulence and backpressure, resulting in relatively low-pressure drop. The flow nozzle is manifold-mounted to the gauge, minimizing leak paths and overall gauge size. Three models are available: 2510FG (0-5 to 0-10 GPM), 2520FG (0-15 to 0-40 GPM), and 2530FG (0-50 to 0-200 GPM). All models have a maximum line pressure of 275 PSI, accuracy of 2 percent full scale, maximum pressure drop of 5 PSID, and turndown of 5-to-1.
