Description
Address of the product
Value type
UINT 16
Notes
Values from 1 to 255 except for 157 (0x9d).
0 is the broadcast address.

Description
Current flow rate
Value type
UINT 16
Notes
Flow rate = [Value (0x0002)*65536 + value (ox0003)]/1000
e.g.: for a flow rate of 123.456 SLPM, the user will read “1 (0x0001)” from
register 0x0002 and “57920 (0xE240)” from register 0x0003, therefore
Current flow rate = (1*65536+57920)/1000 = 123.456
Totalizer

Description
Totalizer or accumulated flow rate
Value type
UINT 32 + UINT 16
Notes
A1 = Value (0x0004) * 65536 + Value (0x0005)
A2 = Value (0x0006)
Totalizer or accumulated flow rate = (A1 * 1000 + A2)/1000
e.g.: for a totalizer or accumulated flow rate of 3452.245 m
3
, the user will read
“0 (0x0000)” from register 0x0004; “3452(0x0D7C)” from register 0x0005, and
“245(0x00F5)” from register 0x0006.
Then, the totalizer or accumulated flow rate
= ((0 + 3452)*1000 + 245)/1000=3452.245.
