Series-VA

Variable Area Flowmeters for Gas & Liquid – Universal Scale, 6-Turn Valve

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

The Series VA Variable Area Glass Flowmeters are designed with easy to read universal mm scale and supplied with correlation charts containing calibration data for air and water.

Glass 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.

Flowmeters are shipped completely assembled and ready for panel mounting. Use an optional acrylic tripod base to convert to self-standing bench mounting.

Note: Calibration data is provided with each unit and is unique to each scale. If you require a calibration certificate for your flowmeter, please see the option under Accessories. (This excludes: VA1043, VA1243, VA1343, VA25425 and VA25025).
