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

, it is recommended to set the initial value of the proportional coefficient to 1% -2% of the range, and then fine tune the integral and derivative parameters. Special attention should be paid during operation: no more than three parameter values should be modified at a time, and the devices operating status should be observed for at least 10 minutes after saving. The flow meter has an internal parameter linkage mechanism. If the medium density parameter is changed, it will automatically affect the temperature compensation coefficient. It is recommended to refer to the Qinghua supporting operating condition manual to adjust the associated parameters synchronously.

2. Hello, may I ask how to reset the cumulative flow of the Henghe flowmeter to zero? Thank you! The cumulative flow reset of Yokogawa flow meters usually requires specific operating steps or settings to be completed, rather than automatic reset like mobile phone flow. The following are some possible reset methods: operate through the dashboard: enter the menu: first, you need to enter the menu system of the Yokogawa flowmeter. This can usually be achieved through a combination of buttons on the dashboard. Navigate to Cumulative Traffic Settings: In the menu, find the settings options related to cumulative traffic. This may require browsing different menu levels. Perform the reset operation on the chaotic Zhaolu line: Once the accumulated traffic setting is found, select the reset or reset option and follow the prompts on the instrument to complete the operation. Connect the Yokogawa flowmeter to the computer using specialized software tools or programmers. Open the software interface: Launch the corresponding software tool and connect to the connected
