Dwyer VA10417 | Variable Area Glass Flowmeter | Glass float, 13.4 SCFH air, 2.33 GPH water
The Dwyer VA10417 glass flowmeter uses a glass float and reaches 13.4 SCFH (6318 ml/min) on air or 2.33 GPH (147 ml/min) on water. It suits lab and pilot-plant liquid or gas measurement, carrier gas metering and process flow indication, and the VA10417 is supplied panel-mount ready.
- Accuracy of the VA10417: ±2% FS (70°F, 14.7 psia), with ±0.25% FS repeatability
- Air and water correlation charts accompany the universal mm scale of the VA10417
- Standard 6-turn needle valve on the VA10417; 16-turn high precision valve offered separately
- Borosilicate glass tube, 10:1 turn-down and two 1/8" female NPT ports (VA10417)
- For bench use, the VA10417 can sit on an optional acrylic tripod base

- Time is saved with a permanently fused ceramic scale with a vertical locator line 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.
- For flow rate control, a standard 6-turn needle valve replaces the requirement for an additional valve, saving money.
- With the optional acrylic tripod base that enables self-standing bench mounting, no extra installation is needed.
- For extremely low flow rates, great sensitivity control and resolution are possible with high precision metering valves including non-rising stems.
