Guidelines for the Operation and Maintenance of Weiliba Flow Meters

Thread Content

　　The Weiba flow meter maintains a leading position among insert-type flow meters thanks to its unique advantages. The Weiliba flow meter is suitable for measuring flow in pipelines of all sizes in field applications, and its advantages are particularly evident when used in large-diameter pipelines. It can be used to measure the flow of various liquids, gases, and vapors, especially in cases involving ultra-low temperature, high temperature, high pressure, or humid fluid media. However, alongside its application and promotion, clients often ask questions regarding maintenance as well. Below is a brief summary of the preparations before putting a VeriFlow meter into use, as well as basic maintenance procedures: 1. Check the installation of the meter: After installing the VeriFlow meter, it is necessary to conduct a thorough inspection to ensure that the welding is secure, the orientation is correct, and there are no leaks after pressure testing. 　　2. Instrument calibration: Read the instructions for the intelligent flow integrator carefully. According to the calculation sheet attached to the Wilo flow meter, set the various parameters in the intelligent flow totalizer correctly to ensure that it can calculate and display the flow rate accurately. If connecting directly to a computer, it is necessary to set the data input format and the appropriate compensation methods within the computer. 3. The instrument wiring must be correct: The Wilo flow meter, together with the differential pressure transmitter and flow totalizer, forms the measurement system; please check carefully to ensure everything is correct before putting it into operation. 　　4. System preheating: After the preparation work for operation is completed, the medium to be measured fills the process pipelines; the Veritas flow meter is temporarily in a closed state. At this point, the balance valve of the three-valve assembly should be kept open, while the high-pressure valve and the low-pressure valve should remain closed. Turn on the instrument power and preheat for 15 minutes. 　　5. System operation: After preheating is complete, open the high-pressure valve and low-pressure valve of the three-valve assembly; the medium to be measured is fed into the differential pressure transmitter. Open the drain valve of the transmitter to quickly discharge any dirty liquid or gas, then close that drain valve. Next, close the balance valve of the three-valve assembly, and the transmitter enters measurement mode. The flow meter also starts operating, displaying the flow rate of the medium in the pipeline.
