First enter the password of the electromagnetic flowmeter to enter the menu and find the caliber column. For example, the caliber is DN50. At this time, if you want to increase the flow rate, change the caliber DN50 to DN65. Naturally, the flow rate will be larger than that of DN50.
Secondly, there is another method to adjust the flow rate. Enter the password to enter the menu and find the K coefficient column. For example, the K coefficient is 1.065. If you want to increase the flow rate, adjust the K coefficient value. Bigger.
The above is how to adjust the flow rate of the electromagnetic flowmeter. If the flow rate is not operated by the staff, the electromagnetic flowmeter will be inaccurate if the parameters inside are moved.
How to debug the electromagnetic flowmeter：
Before debugging the electromagnetic flowmeter, the pipeline and flowmeter should be thoroughly inspected, including the cleaning of pipeline debris, and the oily medium pipeline does not need to be dried. The pre-commissioning inspection also includes the inspection of electrical wiring. First, check the connection of the wiring to ensure that the grounding is reliable before performing other wiring tests to avoid capacitive effects of the wiring, storage of electricity, or damage to the instrument by the measuring power supply. . In addition, insulation resistance and grounding resistance tests are also required.
Water-passing debugging: Whether it is measuring the water-based medium suspension liquid or the oily medium, the electromagnetic flowmeter should simulate the temperature, pressure, flow rate and other conditions of the actual measured medium for water debugging before the formal debugging. If an abnormality occurs during the water flow test, or the parameters are missing, the meter should be tested individually or sent to the production unit for verification.
System investigation test: After the electromagnetic flowmeter has completed the single function water test, and the control host has completed the preliminary debugging, the system can be debugged. The oily medium pipeline needs to be dried before passing the measured medium for system operation. When the system is debugged, the host should perform a code scan on each measuring point in advance to ensure that all instrument components are in normal working conditions before functional debugging can be performed. During functional debugging, the host system reads the parameters of each instrument, critical value alarm test, etc., and then writes the control data, debugs them one by one, and sends the relevant data to the relevant upper computer for analysis.
