New, fully integrated differential pressure (DP) flowmeters from Orange Research are compact and rugged, with directly connected, large-throated, non-clogging flow nozzles. At half the cost, this long life, wear-resistant design is superior to over-sized, over-priced products. With a unique integrated design, ordering, installation, and maintenance is simplified. Simply select desired flow rate and material and everything is supplied in one compact package. The new product line features large, low-pressure-drop flow nozzles; easy-to-read 3.5-inch dials; versatile ½-inch to 2-inch NPT porting; and a choice of brass, stainless steel, or aluminum bodies suitable for a wide 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. It is a low-cost solution that wears better than sharp-edged orifice plates (which often change readings over time due to wear, even with non-abrasive fluids) and competes with the performance of prohibitively expensive venturis. In our design, the flow nozzle is manifold mounted to the gauge minimizing leak paths and overall gauge size. Other designs are much larger and do not fit into tight enclosures. 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% F.S., maximum pressure drop of 5 psid, and turndown of 5:1.
