The electromagnetic flowmeter has high precision, good linearity and stable operation, which improves the accuracy of measurement and the reliability of data.
New flow meters are constantly emerging, with various varieties and different performances. Their use conditions and technical parameters are also different. Based on the actual application conditions, existing problems, and installation of the various flow meters used in the past, we The difficulty, performance-price ratio and other issues were carefully analyzed, compared and demonstrated, and it was believed that the electromagnetic flowmeter has the advantages of sensitive response, good linearity, high accuracy, and is not affected by factors such as 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 reliability of data, and overcomes the unstable operation of some instruments, resulting in measurement data distortion. Untrustworthy question. After many on-site comparisons, the errors were all within the control range, which enhanced trust in the instrument, ended the unscientific measurement method of calculating water volume based on the performance curve of the water pump, and effectively relied on the data collected by the instrument to avoid Human factors.
2. The electromagnetic flowmeter has a simple structure. The sensor has no movable parts. There is no measurement error or instrument failure caused by mechanical movement wear or impurity entanglement. Therefore, the failure rate is very low and the amount of maintenance is greatly reduced. This saves a lot of manpower and material resources.
3. The electromagnetic flowmeter has a variety of interface circuits, which can be easily connected to data collection terminals or computers to realize automation of data collection, analysis, and management.
Management of electromagnetic flowmeters:
1. Establish an operation file for electromagnetic flowmeters, including the manufacturer, model, production date, installation location, pipe diameter, and calibration time of the flowmeter. etc. to facilitate maintenance and management of the instrument.
2. Strengthen inspection and inspection work and conduct regular testing and calibration. We mainly use two methods. One is to use a relatively high-precision portable flowmeter and an electromagnetic flowmeter for measurement comparison; the other is to use a flow meter calibrator to calibrate the flow converter and check various items. Check whether the technical indicators are correct and archive the test data.
3. Compare the test data with previous test results, carefully analyze and study the suspicious data, find possible causes, deal with them in a timely manner, and make an analysis report on the operation of the flow meter.
