Table 5.2.4: Registers
Functions Description Register Modbus reference
Address Product address (R/W) 0x0001 40002 (0x0001)
Flow speed Current flow speed (R) 0x0002 ~ 0x0003 40003 (0x0003)
Baud rate Communication baud rate (R/W) 0x0015 40022 (0x0015)
Temperature Temperature (R) 0x0025 40038 (0x0025)
Humidity Humidity (R) 0x0026 40038 (0x0039)
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 255; 0 is the broadcast address; the default value is 1.
Flow speed 0x0002 ~ 0x00o3
Write N
Read Y
Description Current flow speed
Value type UINT 32
Notes
Flow speed = [Value (0x0002)*65536 + value (ox0003)]/1000
e.g.: for a flow speed of 20.34 m/sec
, the user will read “ 0 ” from register
0x0002 and “ 20340 ” from register 0x00 03, therefore
Current flow speed = (o*65536+20340)/1000 = 20.34 m/sec
Baud rate 0x0015
Write Y
Read Y
Description Communication baud rate
Value type UINT 16
Notes Value=0: 4800; 1: 9600; 2: 19200; 3: 38400. The default value is 3.
Temperature 0x0025
Write N
Read Y
Description Measured temperature data
Value type UINT 16
Notes Temperature = value (0x0025) /100 °C
Humidity 0x0026
Write N
Read Y
Description Measured humidity data
Value type UINT 16
Notes Humidity = value (0x0026) /100 %RH.
