1. Detailed steps and precautions for cumulative zeroing of Xinier flowmeter
The cumulative zeroing of Xinier flowmeter should be strictly executed according to the operation manual, with the focus on stabilizing the equipment status and standardizing the operation process. 1. Detailed steps: Preparation work: Ensure that the sliding protection equipment is in a stable operating state, check whether the sensor surface is clean and undamaged, and confirm that the installation and wiring are correct. ② Shut off fluid: Cut off the fluid flow in the pipeline through a valve, and balance the upstream and downstream pressures during operation to avoid pressure shock causing sensor damage. ③ Enter zeroing mode: Depending on the device model, enter the zeroing function interface through a combination of buttons or menu selection (follow the user manual instructions). ④ Stable signal: In zeroing mode, wait for the sensor output signal to stabilize, usually taking several seconds to minutes. ⑤ Perform zeroing: After the signal is stable, follow the instructions in the manual to perform the operation. The flowmeter will automatically calibrate the zero point and reset the accumulated data. two Note 1: Data backup: Record the current cumulative traffic value before execution to prevent important data loss. ② Pressure control: When closing the valve, ensure that the upstream and downstream pressure difference is close to zero to avoid sudden pressure damage to the equipment. ③ Follow the manual: There are significant differences in the operating methods for different models, and misoperation may cause equipment abnormalities or reset, resulting in stool failure. ④ Environmental requirements: Avoid operating in environments
2. Detailed explanation of the zeroing steps for Kaifeng Hengman flowmeter
The zeroing 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 corresponding to each type of call.
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 reset2. 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 opera
