Electromagnetic flowmeter maintenance management method introduction

New types of flow meters are constantly emerging, with a wide variety of products and different performances. Their use conditions and technical parameters are also different. According to the actual application, problems, installation difficulty and performance of various flow meters used. The price ratio and other issues have been carefully analyzed and compared. It is believed that the electromagnetic flowmeter has the advantages of sensitive response, good linearity, high precision, and no influence on the temperature and viscosity of the measured medium during the measurement process.
1. The electromagnetic flowmeter has high precision, good linearity and stable operation, which improves the accuracy of measurement and the credibility of data, and overcomes the problem that some instruments are not stable, which results in unreliable measurement data. After many on-site comparisons, the error is within the control range, which enhances the trust level of the instrument, and ends the unscientific measurement method of calculating the water volume according to the performance curve of the water pump, and the data collected by the instrument is taken as the standard, avoiding Human Factors.
2. The electromagnetic flowmeter has a simple structure, the sensor has no moving parts, and there is no measurement error or instrument failure caused by mechanical movement wear or impurity entanglement, so the failure rate is very low, the maintenance amount is greatly reduced, thereby saving a lot of manpower and material resources.
3. The electromagnetic flowmeter has a variety of interface circuits, which can be easily connected with the data acquisition terminal or computer to realize data acquisition, analysis and management automation.
Management of electromagnetic flowmeter:
1. Establish an electromagnetic flowmeter operation file, including the manufacturer, model, production date, installation location, pipe diameter, calibration time, etc. of the flowmeter to facilitate maintenance and management of the instrument.
2. Strengthen the inspection inspection work and conduct regular test calibration. We mainly use two methods. One is to use a relatively high precision portable flowmeter to measure the comparison with the electromagnetic flowmeter. The other is to use a flowmeter checker to verify the flow converter and check each The technical indicators are correct and the test data is archived.
3. Compare the test data with the previous test results, carefully analyze the research on the suspicious data, find out the possible causes, solve the problem in time, and make an analysis report on the flowmeter operation.
