How does electromagnetic flowmeter adjust data
Electromagnetic flowmeter how to adjust the data, electromagnetic flowmeter before the calibration, the use of pipelines and flowmeters to do a thorough inspection, including the removal of pipeline debris, oil medium pipelines do not need to do dry treatment.The inspection before calibration is also the inspection of the circuit of the package electrical appliances. First, the inspection of the connection of the circuit shall be done to ensure the reliable grounding, and then the test and inspection of other routes shall be done to avoid the capacitive effect of the circuit, the storage of electric quantity, or the damage of the measuring power to the instrument and equipment.In addition, also need to do insulation resistance and grounding resistance.
Water commissioning: before the formal commissioning, the electromagnetic flowmeter should simulate the temperature, pressure, flow rate and other conditions of the actual measuring medium.In case of any abnormality or missing parameters during the water test, the unit should be tested or sent to the manufacturer for verification.
System investigation: electromagnetic flowmeter can carry out system debugging after the completion of single function water test and the preparatory debugging of the control host.The oil medium pipeline shall be dried before passing into the medium under test for system operation.During system debugging, the host machine should conduct code scanning for each measuring point in advance to ensure that all instrument parts are in normal working state before carrying out functional debugging.During functional debugging, the host system will read the parameters of each instrument, conduct critical value alarm test, etc., then write the control data, debug one by one, and send the relevant data to the relevant upper computer for analysis.
