Consumption counter with integrated measuring section (1/4″ to 2″ with/without weld neck flange)

Application-technological features of the consumption counters VA 420:

• Easy and affordable installation
• Units freely selectable via keypad m³/h, m³/min, l/min, l/s, kg/h, kg/min, kg/s, cfm
• Compressed air counter up to 1,999,999,999 m³. Resettable to “zero” via keypad
• Analogue output 4…20 mA, pulse output (galvanically seperated)
• High measuring accuracy also in the lower measuring range (ideal for leakage measurement)
• Negligibly small loss pressure
• Calorimetric measuring principle, no additional pressure and temperature measurement necessary, no mechanically moved parts
• Gas types adjustable via software (nitrogen, oxygen, CO2, nitrous oxide, argon)

Application range of VA 420:

• Compressed air balancing, compressed air consumption measurement
• Leakage air / leak rate determination
• Mobile compressed air measurement in front of single machines / plants
• Flow measurement of process gases like e. g. nitrogen, CO2, oxygen, argon, nitrous oxide
• Flow measurement at nitrogen generators
