1. Wiring diagram and connection method of Yokogawa flowmeter

The wiring core of Yokogawa vortex flowmeter lies in the correct connection of power supply, signal line, and output signal. The use of DC power supply and strict distinction between frequency and analog signal terminals are the key to success. The wiring diagram of the Yokogawa vortex flowmeter clearly divides three functional areas: power wiring, signal wiring, and output signal wiring. Understanding this structure is the first step to proper connection. 2. Specific connection method 2.1 Power supply wiring Flow meters usually use DC power supply with a voltage range between 12V and 36V. When connecting, the positive pole of the power supply needs to be connected to terminal V+, and the negative pole needs to be connected to terminal V -

2.2 Signal line wiring. This part includes two types of signal lines. One end of the frequency output signal line (usually green or blue) should be connected to the F+or Fout terminal of the flowmeter, and the other end should be connected to the frequency input terminal of the control device. One end of the analog current output signal line (usually white or yellow) is connected to the I+or Iout terminal, and the other end is connected to the analog current input terminal of the control device. 2.3 Output signal wiring: Select the output signal type according to the actual measurement requirements. If a frequency signal is required, lead the frequency output line to the frequency input port of external devices such as PLC or computer. If an analog signal is required, use an analog current of 4-20mA and connect the analog current output line to the corresponding input terminal of the external device. Make su

re to confirm that the input range of the device matches the output setting of the flow meter. 3. Wiring precautions: When operating, be sure to refer to the official wiring diagram to ensure that each wire is connected to the stove at the correct terminal. Choose a power supply voltage that meets the specifications and pay attention to polarity to prevent reverse connection. Carefully distinguish between frequency signals and analog signal lines to avoid confusion. During the wiring process, it is important to ensure that all connections are secure to prevent issues such as poor contact or short circuits. Finally, there may be differences in the flow meters of different models, so please carefully read the accompanying user manual and technical instructions before actual operation.

2. Wiring method for electromagnetic flowmeter

Tools: electromagnetic flowmeter, electrical tape, wire stripping pliers.

. Process:

1. The area stove is divided into internal and external wiring;

2、 The internal wiring usually consists of 5 wires, connecting the sensor to the conversion amplifier. XY，ACB， Two wires are connected to the magnetic coil, XY， Electrode wiring ACB, two are electrode wiring AB, and one is grounded C;

3. External wiring is generally the power supply connection end. Two wires, signal output lines: six, usually two 4 to 20mA output lines, two RS232 communication lines, and two RS485 communication lines. There is also a grounding terminal wire on the cylinder. Attention: Distinguish the product type from the wild front number, and pay attention to grounding.
