Ideal for measuring the flow of compressed air and gas! Ease of use is obvious at a glance!
The VA420 series is designed to be compact and is an economical type mass flow meter that can accommodate relatively small compressed air piping (minimum: 8A) in pneumatic systems. For relatively large compressed air piping from 50A to 300A, the VA400 series is more suitable. The gases that can be measured include not only air but also nitrogen, oxygen, CO2, and others. The VA420 series is an "inline type (integrated with piping)," while the VA400 series is a "vertical line insertion type." 【Specifications】 ○ Measurement items: m³/h, ℓ/min (1000 hPa, 20°C); however, compressed air and gas are measured in Nm³/h, Nℓ/min (1 atm, 0°C, normal) ○ Unit switching function via keypad operation: m³/h, m³/min, ℓ/min, ℓ/s, ft/min, cfm, m/s, kg/h, kg/min ○ Measurement principle: Thermal mass flow measurement (mass flow) ○ Sensors: Silicon chips x 2 ○ Measurement targets: Gases, air, and gas For more details, please contact us or download the catalog.
