Dwyer DR120120 | Direct Reading Glass Flowmeter | 0.02 GPH water, Glass Float
For water flow at 0.02 GPH, Dwyer lists the DR120120, a variable area glass flowmeter fitted with a glass float. Because the DR120120 has a direct reading scale, flow can be read without correlation charts.
- Glass float; flow rate 0.02 GPH water
- Accuracy ±5% of full scale at 70°F (21.1°C) and 14.7 psia
- Repeatability ±0.25% of scale reading
- 10:1 turn-down ratio
- Rated to 250 psig (17 bar) and 250°F (121°C)
- 1/8 in female NPT connections, vertical mounting

- 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.
