1. Detailed explanation of the reset steps for Kaifeng Hengman flowmeter

The reset steps for Kaifeng Hengman flowmeter need to be operated according to the specific instrument type. Common categories include electromagnetic, target, mass flowmeter, and universal accumulator. The following is a detailed operation process for each type of call and corresponding operation Electromagnetic flowmeter zeroing process • Preparation before zeroing: Confirm that the flowmeter is powered on normally, the pipeline is filled with the measured medium, and there are no residual bubbles or impurities. • Operation process: 1 To enter the instrument engineering mode, please refer to the accompanying user manual for the entry methods of different models Find the "Reset" or "Zero" option in the engineering mode menu Select zeroing method: Automatic zeroing is automatically completed by the instrument and the tracking table; Manually resetting requires inputting the corresponding cumulative traffic value 4 After confirming the operation, wait for the instrument to reset to zero. Closing check: Check if the accumulated flow value has reset to zero, exit the engineering mode, record the time and executor of this reset

2. Target flow meter reset process • Pre confirmation: Only when there is no medium passing through the pipeline and the instrument has zero drift, the reset operation needs to be performed. Standard operating procedures: 1 Close the backend valve of the flowmeter and slowly open the frontend valve to fill the flowmeter with the measured medium Run the flowmeter at maximum flow rate for about 5 minutes Close all valves at the front and rear ends and confirm that the medium inside the pipeline is completely statio

nary Complete zeroing according to the zero operation instructions provided by the instrument. Special case handling: 1 High temperature flowmeter without temperature compensation: Wait for the temperature of the transition piece to stabilize before closing the valve and letting it stand. Confirm that the flow rate is zero before resetting it to zero Flow meter with pressure compensation: If there is no medium flow but there is still pressure display, pressure reset must be completed first before executing flow reset High temperature flowmeter with temperature compensation: If zero drift occurs after installation, it needs to be reset at room temperature.

3. Mass flowmeter reset process • Three reset methods: 1 Panel operation: Step by step through the physical buttons and menus on the instrument panel. The specific steps are subject to the product manual Software operation: Using the accompanying remote control software, select the reset option on the software interface to perform operation 3 External signal control: Connect the signal source of the automation control system to trigger the reset command. Operation precautions: Backup the instrument data before resetting, confirm that the operation is correct, and strictly follow the requirements of the product manual throughout the process.

4. General accumulator reset process: Press the "ENTER" key directly, use the "↑" and "↓" keys to select "Yes" to confirm the reset, and choose corresponding options such as "Do not reset", "Reset all accumulators", "Net accumulator", "Negative accumulator", etc; If you need to restore the factory default settings, press the "←" key in this window.
