變節面流量計F VA Minix
The F VA Minix variable area meters are used to measure the volume of transparent liquids and gases passing through closed piping. The built-in needle valve permits manual control of flow rates. Standard scales are available for liquids with a density of 1 kg/l (62.43 lbs/cu.ft) and for air. The scales must be recalculated for all other media depending on the physical characteristics.
