3 Electrical Connection
The Insert electromagnetic flowmeter converter can be divided into integrated converter and separated
converter, and the wiring diagram is shown in Figure 1 and Figure 2.
When wiring, please note:
a) RS485 communication cable needs to use two-core twisted pair shielded wire;
b) The same cable shall not be used for the power line and 4mA~20mA DC signal line. Two cables
shall be connected separately.
