2. How to adjust the electromagnetic flowmeter?
The adjustment method of electromagnetic flowmeter is as follows
1. Firstly, you need to enter the password to enter the menu and find the caliber setting column.
. For example, if the caliber is set to DN50, to increase the flow rate, the caliber can be modified to DN65, which will naturally increase the flow rate. Secondly, the flow rate can also be changed by adjusting the K coefficient. Enter the password to enter the menu and find the K coefficient column. For example, if the K coefficient is 1.065, increasing the K coefficient value will correspondingly increase the flow rate. Attention: Non staff members should not adjust the flow parameters arbitrarily to avoid affecting the accurate measurement of the electromagnetic flowmeter. The debugging steps of electromagnetic flowmeter are as follows: Before debugging, the pipeline and flowmeter should be thoroughly inspected, and any debris in the pipeline should be cleaned. For oily medium pipelines, drying treatment is not required. Check the electrical circuit, first check whether the grounding is reliable, and then perform other circuit tests to avoid capacitive effects of the circuit or damage to the instrument caused by the power supply2. Water commissioning: Regardless of whether it is an electromagnetic flowmeter for aqueous or oily media, it should simulate actual conditions for water commissioning before formal commissioning, including temperature, pressure, and flow rate
3. System commissioning: After completing single function testing and preparing the control host for commissioning, carry out system commi

1. The parameter settings for electromagnetic flowmeter are usually within a certain range, and may vary among products from different manufacturers. Please refer to the product manual for details. The flowmeter determines whether the pipeline is full based on the real-time measured fluid resistivity value. The resistivity value in the full pipeline state is defined as 100%. When the fluid is full, calibrate the empty tube measurement value to 100%. When the fluid level in the pipeline is lower than the measuring electrode and comes into contact with air, the resistivity value will increase. The alarm threshold for the empty pipe is set at around 90%. When the resistivity value exceeds this threshold, the flow meter will display an empty pipe alarm signal. When the fluid is full, the measurement value of the empty tube can be calibrated to 100%. However, when the liquid level is below the electrode, the measurement value of the empty tube will exceed 1000%. Therefore, setting the alarm value of the empty tube at around 900% can calculate the status of the empty tube.
