RS 485 setup
Set the Current Loop output value according to the flow value
4mA, and 20mA. The flow unit is GPM
2.
Alarm Value
(Optional)
Enter the low alarm value; (if the measured flow is lower than
the low alarm value), the alarm relay will be activated.
Enter the high alarm value; (if the measured flow is higher
that the high alarm value), the alarm relay will be activated.
If the flow is below the cut-off the flow indication on the display will be
zero. (This function can prevent the flow meter from reading flow after
a pump is shut down but there is still liquid movement in the pipe, which
would result in a flow total error.)
Generally, 0.03ft/s is recommended to enter as the low flow cut off
point. The low flow cutoff value has no relation to the
results once the velocity increases over the low flow cutoff value.
This window is used to set RS 485 serial port . It must match the
equipment's connected parameters .
First select baud rate: 2400,4800,9600,19200 are selectable Then
select : None . Data length :8 Stop bit is fixed length . Factory
default value for serial port parameter is ''9600,8,None,1''
