1. Correct wiring method for vortex flowmeter
The correct wiring method for vortex flowmeter is as follows: power line wiring: clarify the power requirements of the vortex flowmeter and select the appropriate power line. Connect the positive pole of the power cord to the "+" end of the flowmeter and the negative pole to the "" end. Ensure the polarity of the power cord is correct to avoid equipment damage. Signal wiring: The output signal of a vortex flowmeter is usually an analog signal of 420mA. Connect the positive pole of the signal line to the "420mA+" terminal of the flowmeter and the negative pole to the "Lujin 420mA" terminal. Ensure that the shielding layer of the signal line is grounded to reduce the impact of electromagnetic interference on the measurement results. Attention: Ensure that all wiring terminals are securely fastened to avoid measurement errors or equipment malfunctions caused by poor connections and poor connections. Avoid threading power lines and signal lines in the same conduit to reduce electromagnetic interference. If on-site debugging or maintenance is required, the power supply should be cut off first to ensure safety.
2. 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 meth
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 sure 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 pr
