Reliability analysis of flow meters

Thread Content

1. The reliability of the system is improved by optimizing the structural design of the instruments. For example, by using a non-stop insertion structure, the flow meter can be replaced without affecting the process operation. 2. The reliability of the instrument itself has improved significantly. Such as metal rotor flowmeters, purge flowmeters, etc. 3. Safety: Some of the fluids to be measured are flammable and explosive, and some locations where the instruments are installed are also flammable and explosive environments; therefore, the selection of instruments, system design, and installation must all comply with explosion-proof regulations. 4. Introduce redundancy techniques. If dual sensors are used and an automatic check is performed to determine whether the sensors are functioning properly, the signal from the faulty sensor will be excluded. 5. Cost savings: In addition to the cost of purchasing the instruments, costs such as those for purchasing accessories, installation and commissioning, operation, spare parts, as well as maintenance and regular calibration are also taken into account. Moreover, the depreciation cost resulting from the average lifespan of the instruments cannot be ignored either. 6. Introduce self-diagnosis technology, and use field buses to send the diagnosis results to the operation station or a dedicated equipment management system (AMS) for display and alarm generation, so as to detect faults promptly and take measures early. 7. Regular maintenance of the flow meter is also essential.
