Question: How much do you know about the management and maintenance of the cable fault tester? Answer: New types of flow meters are constantly emerging, with a wide variety of different performances, and their use conditions and technical parameters are also different. We are based on the various flow meters used in the past. Problems: management and maintenance of cable fault testers How much do you know? Answer: New types of flow meters are constantly emerging, with a wide variety of different performances, and their use conditions and technical parameters are also different. , performance-price ratio and other issues have been carefully analyzed, compared and demonstrated, and it is believed that the infrared thermometer has the advantages of sensitive response, good linearity, high accuracy, and is not affected by the temperature, viscosity and other factors of the measured medium during the measurement process. . 1. The cable fault tester has high precision, good linearity and stable operation, which improves the accuracy of measurement and the reliability of data, and overcomes the problem of unreliable measurement data caused by unstable operation of some instruments. After many on-site comparisons, the errors are all within the control range, which enhances the confidence in the instrument, and ends the unscientific measurement method of calculating the water volume according to the performance curve of the pump. Human Factors.
2. The cable fault tester 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, and the maintenance amount is greatly reduced, thus saving a lot of manpower and material resources. . 3. The cable fault tester has a variety of interface circuits, which can be easily connected with the data acquisition terminal or computer to realize the automation of data acquisition, analysis and management. Management of cable fault tester 1. Compare the test data with the previous test results, carefully analyze and study the suspicious data, find out the possible causes, deal with them in time, and make an analysis report on the operation of the thermometer.
2. Establish the operation file of the cable fault tester, including the manufacturer, model, production date, installation location, pipe diameter, calibration time, etc. of the thermometer, so as to facilitate the maintenance and management of the instrument. 3. 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 thermometer and cable fault tester to measure and compare; the other is to use a flow meter calibrator to verify the flow converter and check Whether the technical indicators are correct, and archive the test data.
