DWYER VA Variable Area Flowmeter
RM 0.00
Description
Series VA Variable Area Glass Flowmeters, 65 mm and 150 mm, ±2% FS Accuracy
DWYER VA Variable Area Flowmeters are designed with easy to read universal mm scale and supplied with correlation charts containing calibration data for air and water. DWYER VA Variable Area Flowmeters are suitable for metering carrier gases, liquid and gas measurement in pilot plants, laboratories, process flow and level indicating. Units are equipped with a standard 6-turn needle valve for flow rate control. High precision metering valves with non-rising stems (sold separately) are available for high sensitivity control and resolution – particularly suited for very low flow rates.
Features
- Permanently fused ceramic scale with vertical locator line reduces parallax and eye fatigue saving time
- Long operating life with thick polycarbonate front shield that protects tube from breakage and serves as a magnifying lens to enhance reading resolution
- Standard 6-turn needle valve for flow rate control eliminating the need for a separate valve reducing cost
- No additional installation required with optional acrylic tripod base which allows for self-standing bench mounting
- High precision metering valves with non-rising stems are available for high sensitivity control and resolution for very low flow rate
