Dwyer DR204732 | Direct Reading Glass Flowmeter | 7.5 GPH Water, 316 SS Float
The Dwyer DR204732 is a direct reading variable area flowmeter with a borosilicate glass tube and 316 SS float, rated for a flow rate of 7.5 GPH of water. Its scale reads the 7.5 GPH range directly, so no correlation chart is needed.
- Flow rate rating: 7.5 GPH (water)
- Accuracy on the DR204732: ±5% FS at 70°F (21.1°C) and 14.7 psia
- DR204732 repeatability of ±0.25% of scale reading
- 1/8" female NPT connections, vertical mounting, 10:1 turndown (DR204732)
- Limits for the DR204732: 250 psig (17 bar) and 250°F (121°C)
- PTFE float stops and 316 SS float in the DR204732

- Time is saved by a permanently fused ceramic scale with a vertical locator line, a background of reflecting lens, and a 1.5 X magnification lens that lessens parallax and eye strain.
- Long operational life and a magnifying lens to improve reading resolution are features of the robust polycarbonate front cover, which also protects the tube from breaking.
- Optical needle valve that reduces costs by doing away with the requirement for a separate valve when controlling flow rate.
- Safety blow-out rear panel incorporated for extra safety and increased protection.
