The flowmeter contains a atmega 16 chip and i am trying to get flowrate and flow totalizer from it via rs485 to ttl converter using a arduino nano
data related to the rs485 signal and data registers –
0x4001 to 0x4003 —> flow rate value
0x4004–>flow rate value unit
0x4005 to 0x4007 –>totalizer value
0x4008–>totalizer value unit
first digit is data bits which is 8b
Second digital is Parity which you select as N for None, E for Even, O for Odd
Third digit is stop bite which you can select as 1 / 2 bits
device id – 025
ide using – arduino ide
