a. Indicating flow rate and quantity
b. Preserving data at power cut and the retaining time will be no less than 5 years.
2.Display: Display in 4 frames with 8 pieces of nixie lights
a.Quantity: 8 digits of decimal number
b.Flow rate: Identifier “F-”, 6 digits of decimal number
c.Before leaving the works, pulse equivalent of the transducers have been set, so the user is not required to set the automatic indicating (the user may conduct fine tuning of the pulse equivalent.).
