Table 5.4: Registers
Functions Description Register Modbus reference
Address Product address (R/W) 0x0001 40002 (0x0001)
Flow rate Current flow rate (R) 0x0002 ~ 0x0003 40003 (0x0003)
Totalizer Totalizer or accumulated flow rate (R) 0x0004 ~ 0x0006 40005 (0x0005)
Baud rate Communication baud rate (R/W) 0x0015 40022 (0x0015)
Gas conversion factor Gas conversion factor (R/W) 0x0016 40023 (0x0016)
Response time Response time or sampling time (R/W) 0x0017 40024 (0x0017)
Offset reset Reset or calibrate offset (R/W) 0x0027 40040 (0x0027)
High flow alarm Set high flow rate alarm (R/W) 0x0031 40050 (0x0031)
Low flow alarm Set low flow rate alarm (R/W) 0x0033 40052 (0x0033)
Write protect Disable a specific parameter entry (W) 0x0014 40021 (0x0014)
The detailed information of each register is described below: Y: enabled; N: disabled
Address 0x0001
Write Y
Read Y
Description Address of the product
Value type UINT 16
Notes
Values from 1 to 247 except for 157 (0x9d).
Broadcast is not enabled, and the default address is 1.
Flow rate 0x0002 ~ 0x00o3
Write N
Read Y
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 0x0004 ~ 0x0006
Write Y
Read Y
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.
