1. The wiring method for Cologne flowmeter 485 is as follows.
1、 Connect the A, B, and ground wires of the Yunjueheng RS485 bus to the macro head of the flowmeter, where the A and B wires are respectively connected to the RS485+and RS485- terminals of the flowmeter, and the ground wire is connected to the ground terminal of the flowmeter.
2、 Next, we need to connect the A, B, and ground wires of the RS485 bus to the control system. After the connection is completed, we need to set the corresponding communication parameters in the control system, including baud rate, checksum, and stop bit, and finally debug and test them.
2. Correct method for 24V wiring of flow meters
There are mainly three types of 24V wiring methods for flow meters, and the core difference lies in the combination of power and signal lines.
. Before wiring, be sure to confirm which system your flowmeter belongs to and strictly follow the product manual for operation. 1. Two wire wiring method: Connect the positive terminal of the 24V power supply to the positive input terminal of the flow meter, and connect the negative terminal of the power supply to the negative output terminal of the flow meter. Features: Only two wires are used to simultaneously provide power and transmit 4-20mA signals. The wiring is the most concise, but it requires a very stable power supply voltage, otherwise it will affect the measurement accuracy.2. Three wire wiring method: the positive terminal of the 24V power supply is connected to the positive terminal of the flowmeter power supply, and the negative terminal of the power supply is connected to the system common ground. The signal output terminal of the flowmeter is separately co
3. Wiring method for the four wire system: Connect the positive and negative terminals of the 24V power supply to the dedicated power supply of the flowmeter.
. The positive and negative output terminals of the flowmeter are respectively connected to the corresponding signal cancellation input ports of the control system. Features: The power and signal channels are completely physically separated, with a total of four wires. The strongest anti-interference ability, suitable for use in complex industrial electromagnetic environments, and the highest stability. Regardless of the approach, safety comes first. Before operation, the power must be turned off and a multimeter must be used to confirm the cables and ports. It is best to perform another continuity check after connecting to ensure there are no errors before powering on for testing.
3. How to wire the Crohn flowmeter
The wiring of the Crohn flowmeter needs to distinguish between internal and external wiring, and the core is to accurately connect the power supply, signal output, and grounding system 1 Before wiring, prepare tools such as electromagnetic flow meters, wire strippers, and electrical tape, and carefully read the product manual to confirm the specific wiring requirements for the model. Internal wiring (connecting sensors and converters) usually has 5 wires: • Excitati
