Overview
The VA40 is a glass tube variable area (VA) flowmeter for flow measurement of liquids and gases. The all-purpose flowmeter is suitable for all basic applications up to +100°C / +212°F and max. 10 bar / 145 psi. Typical applications include flow measurement of flushing, purging or inert gases or heating and cooling circuits.
