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. How to reset the cumulative flow of the MF4003 mass flowmeter
The reset operation of the cumulative flow of the MF4003 mass flowmeter should be strictly followed according to the official operating procedures of the device. Some models require access to the permission menu for operation, and do not reset it arbitrarily to avoid affecting the compliance of the measurement data.
Basic preparation items - Confirm that the equipment is in a stable operating state, stop the relevant media delivery first, and avoid data abnormalities during the zeroing process - In some industrial scenarios, historical measurement data needs to be retained for ledger records before zeroing, in compliance with metrological compliance requirements - Some MF4003 models require the use of matching calibration software or specialized debugging tools, and do not use unofficial tools for operation Conventional reset operation steps • Enter the device menu: Enter the reset interface through the key panel of the flowmeter body, and press the [Settings], [Maintenance], and [Measurement Reset] menu paths in sequence. Some models require the input of an administrator password (default passwords are generally 0000 or 1234, depending on the device manual) • Confirm the reset operation: After entering the reset interface, select the "Accumulated Flow Reset" option, and the system will p
