1. How to Zero Digital Flow Meter

The core operations of digital flow meter zero adjustment include stopping fluid flow, entering zero adjustment mode, calibrating and verifying results. The specific operation steps need to be adjusted according to the equipment model. 1. Confirm the preparation work by first ensuring that the fluid in the pipeline is completely stationary, and closing the upstream and downstream valves to avoid interference with liquid flow. Check the power connection and display status to ensure that the device is in a normal power on state and avoid zero adjustment failure due to hardware issues. 2. Enter zero adjustment mode. Depending on the design differences of the device, there are usually two ways: 1. Directly press the zero button: Some flow meters are equipped with dedicated zero adjustment buttons, which can be short or long pressed to trigger the calibration program. • Menu operation zeroing: Enter the system menu by pressing the panel buttons, search for "Zero Calibration" under the "Settings" or "Advanced Functions" category, and select the pure spine option.

3. Perform zeroing operation to start calibration, keep the device stationary for about 10-30 seconds, and avoid vibration or electromagnetic interference during this period. The flowmeter will automatically collect the current signal and set it as the zero reference value. If the environment fluctuates greatly, it is recommended to repeat the operation 2-3 times to improve accuracy. After saving and verifying the calibration, press the confirm button to save the parameters. Observe the display screen and check if the value returns to zero. If there is still a deviation, repeat the above steps. Some devices support au

2. How to adjust parameters of flow meter

Flow meter parameter adjustment operation process: Equipment: Flow meter

1. In the initial interface, you can right-click to enter the system settings menu, enter the password, and press the left button to confirm and enter the settings system.

2、 After entering the system, you can see that there are instantaneous flow parameters in the settings menu, which can be adjusted by moving up and down and pressing the right button to enter.

3、 When entering the second level menu of instantaneous flow setting parameters and scroll width, find the scale flow setting and use the up and down keys to prepare for movement. Right click to enter the scale flow setting menu.

4、 After entering the scale flow setting item, you can set the scale flow, which is the method for modifying the range of the electromagnetic flowmeter. The function of the flowmeter is fully digital processing, with strong anti-interference ability, reliable measurement, high accuracy, and a flow measurement range of up to 1500:1. Ultra low EMI switching power supply, suitable for a wide range of power supply voltage changes, with good EMI resistance performance. Adopting a 16 bit embedded microprocessor, it has fast computing speed, high accuracy, programmable low-frequency rectangular wave excitation, improved stabilit
