Dwyer VA10413 | Variable Area Glass Flowmeter | Glass float, 4.32 SCFH air, 0.63 GPH water
Dwyer VA10413: a variable area glass flowmeter carrying a glass float, with maximum flows of 0.63 GPH (40 ml/min) water and 4.32 SCFH (2040 ml/min) air. The VA10413 is supplied assembled for panel mounting and is used for carrier gases, process flow indication and lab or pilot-plant measurement.
- ±2% FS accuracy and ±0.25% FS repeatability on the VA10413
- Universal mm scale (65 or 150 mm) plus air and water correlation charts for the VA10413
- VA10413 flow control: 6-turn needle valve, optional 16-turn high precision metering valve
- Two 1/8" female NPT ports and a borosilicate flowtube with 10:1 turn-down on the VA10413
- Vertical mounting; an optional acrylic tripod base turns the VA10413 into a bench unit

- 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.
