Note
:
(1) The internal accumulator is been presented by a LONG number for the integer part
together with a REAL number for the decimal fraction. In general uses, only the integer part
needs to be read. Reading the fraction can be omitted. The final accumulator result has a
relation with unit and multiplier. Assume N stands for the integer part (for the positive
accumulator, the integer part is the content of REG 0009, 0010, a 32-bits signed LONG
integer,), Nf stands for the decimal fraction part (for the positive accumulator, the fraction part
is the content of REG 0011, 0012, a 32-bits REAL float number,), n stands for the flow
multiplier (REG 1439).
then
The final positive flow rate=(N+Nf ) ×10n-3 (in unit decided by REG 1438
)。
The meaning of REG 1438 which has a range of 0~7 is as following:
0 cubic meter (m

)
1 liter (L)
