The King 7650 series rotameter is a chemically resistant, borosilicate glass tube meter series for liquid service. It features a clear polycarbonate shield surrounding the glass metering tube, providing protection while maintaining visibility. It is assembled in a 304 SS tie rod frame for robust construction. It offers CPVC and Hastelloy C-276 as optional materials, suitable for a wide range of chemical and corrosive applications. O-ring seals allow for easy disassembly and cleaning.

Flow capacities range from 0.25 to 26 GPM for water service. The meter is available with 3 inch (80mm) or 5 inch (127mm) scales. Accuracy is ±5% for the 5in scale and ±3% for the 3in scale. Turndown ratio is 10:1 to 12.5:1 with repeatability of 0.5%. Float material options include 316L Stainless Steel or Hastelloy C-276 for corrosion resistance.

Maximum temperature rating is 140°F (60°C) with maximum pressure of 100 psig. Ambient temperature range is 33 to 125°F (1 to 52°C). Vertical FNPT inlet/outlet fittings are available in PVC or CPVC. Elastomer options include EPR, Buna-N, Viton, or Kalrez to accommodate various chemical compatibility requirements.
