The King Instrument 7200 series rotameters utilize a float and tapered tube design. As a result they have longer, more linear scales, better pointer stability, and 40% greater accuracy than competitively priced products. They are precision-machined from durable cast acrylic stock and have 316L stainless steel internal components.

Depending on your application, you have a choice of brass, aluminum, PVC, or stainless steel fittings. The 7200 series features a 5 inch (127mm) direct reading scale with flow capacities from 1 to 200GPM for water and 4 to 245SCFM for air. Accuracy ranges from ±3% to ±6% full scale with turndown ratios of 10:1 to 12.5:1 and repeatability of 1 to 2%.

For water service, the maximum temperature is 130°F (54°C) with a maximum pressure rating of 150 psig. For air service, the maximum temperature is 100°F (38°C) with a maximum pressure rating of 100 psig. Ambient temperature range is 33 to 125°F (1 to 52°C).
