1. Parameter Debugging Tutorial for Electromagnetic Meter Remote Control
The essence of parameter debugging for electromagnetic meter remote control is to calibrate the electromagnetic flowmeter, with the key being zero calibration and range calibration. 1. Preparation before debugging • Check installation conditions: Ensure that the pipe is full and free of bubbles, the front and rear straight pipe sections meet the requirements (5D in the front and 2D in the back, where D is the pipe diameter), and the grounding resistance is ≤ 10 Ω. • Tool preparation: standard signal source, multimeter, portable ultrasonic flowmeter (for comparative verification). Xiangqing 2. Specific debugging steps 2.1 Zero point calibration - Stop the pump and drain the pipeline to ensure no liquid flow. Excavate - enter the equipment menu (such as Calibration → Zero Adjust). -Perform zero calibration and save after the display is stable. -Verify whether the air traffic control status flow display is reset to zero (error should be within ± 0.1%). -Pay attention to electrode cleaning and stable environmental temperature
2.2 Range calibration • Standard table comparison method: Connect standard tables in series, adjust to 20%, 50%, and 100% flow points, and compare the readings to adjust the range factor (K factor). • Current output calibration: Enter the output menu (such as 4mA/20mA Adjust), enter the standard value, measure and adjust with a multimeter to an error of ≤ 0.1%
3. Verify after calibration - recheck the zero air tube status. -Multi flow point (low/medium/high) comparison standard table or process data. -Record data and regularly review stability
4. Common problems include large errors after calibration: c

2. How to set the unit of the electronic flowmeter
The unit setting of the electronic flowmeter is usually completed through the device menu operation, but the specific steps of grinding and adjusting vary depending on the brand and model, and should be based on the equipment manual.
. 1. Most electronic flow meters enter the settings menu through a specific combination of buttons on the control panel (such as the "Menu" button and the "Confirm" button) when entering the menu interface. Some models support remote operation using a matching remote control or configuration through running dedicated software connected to a computer. Before operation, be sure to carefully read the instructions and familiarize yourself with the menu structure. 2. Select the appropriate unit and find the unit setting option in the menu. Choose the volume flow unit (such as L/s, L/min, m ³/h) or mass flow unit (such as kg/h, t/h) according to the measurement requirements. When selecting, it is necessary to ensure consistency with the units of other equipment and control systems in the process flow. After confirming and saving the selected units, follow the equipment prompts to confirm the operation (usually by pressing the "confirm" button or the save button in the software). After the setting is completed, the flowmeter display screen will show real-time measurement data in the new unit.3. Parameter Calibration Process for Remote Control of Plug in Electromagnetic Meter
