1. Parameter Setting Method for Henghe Flow Meter
The core operation process for setting parameters for Henghe Flow Meter consists of three levels: basic parameter setting, system optimization adjustment, and software collaborative configuration. 1. Basic parameter setting process ① Enter setting mode: Press and hold the "SET" button and turn on or reset until the screen displays "SETUP". ② Select parameter item: Use the left and right arrow keys to select the target parameter, press the "ENT" key to confirm and view the current value. ③ Numerical modification: Use the left and right arrows to adjust the numerical value. When the new value takes effect, the device will emit a brief prompt sound. ④ Save parameters: Press the "SET" button to trigger the save, and the screen will display "SAVE" with a long tone indicating successful storage. ⑤ Exit operation: Wait for 5 seconds for automatic exit or press and hold the "SET" button for 10 seconds to force exit
2. System key parameter adjustment ① Gain adjustment: Changing the signal amplification factor directly affects the accuracy of flow measurement, and needs to be debugged step by step according to the characteristics of the pipeline medium. ② Integral time: Set the range from 0.1 seconds to 1 minute, take the low value for high-frequency response scenarios, and recommend a steady-state measurement of 0.5 seconds or more. ③ Bias current: used to correct zero drift. It is recommended to perform zeroing calibration in an empty tube state.
3. Software collaborative configuration: ① Data acquisition: Set the acquisition frequency to 3-5 times the flow fluctuation period to ensure complete signal recording. ② Control algorithm: When using PID algorithm
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 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
