Description

Technical Field

[0002] As one of the most important instruments in industrial measurement, flow meters are widely used in various industries, such as petroleum, natural gas, chemical industry, water treatment, food and beverage, pharmaceuticals, etc. These industries have extremely high requirements for the precise measurement of fluids, because the accurate measurement of fluids is directly related to production efficiency, cost control and product quality.

[0003] Existing flow meters have the following defects: First, they lack remote monitoring capabilities. Current flow meters generally lack wireless transmission functions and rely on manual on-site viewing of meter readings, which is not only inefficient but also increases labor costs. This limitation significantly restricts the intelligence and flexibility of the production process; Second, the use of a single technology for flow monitoring has obvious limitations. For example, turbine flow meters perform poorly when facing impurities and high-viscosity fluids, and also generate unnecessary pressure losses; and although electromagnetic flow meters have excellent performance, they are difficult to use when facing low-conductivity liquids (such as petroleum products, agricultural chemical solvents, etc.) and high-temperature environments, which greatly limits their scope of application and cannot meet the diversified and complex industrial measurement needs; Third, the maintenance cost is high and affects production continuity. Once the flow meter fails, the current maintenance method often requires interrupting the flow of pipeline fluids, which not only increases the complexity and cost of maintenance, but more importantly, seriously interferes with the continuity and efficiency of the production process.

[0020] Working principle: When installing and using the present invention, first assemble the main pipe 1, the electromagnetic flowmeter assembly 2, the wireless transmission assembly 3 and the turbine flowmeter assembly 4, install the electromagnetic flowmeter assembly 2 on the second branch pipe 7 through the third flange 12, the first bolt group 13 and the fifth flange 22, install the turbine flowmeter assembly 4 on the first branch pipe 6 through the fourth flange 14, the second bolt group 15 and the sixth flange 42, install the wireless transmission assembly 3 on the mounting plate 11 on the connecting column 10, and then connect the main pipe 1 to the fluid pipeline through the first flange 5, select the electromagnetic flowmeter assembly 2 or the turbine flowmeter assembly 4 for flow monitoring according to the characteristics of the transmitted fluid, and open the corresponding The first valve 8 or the second valve 9 on the branch pipe of the component connection realizes the conduction on one side of the fluid transmission. When the electromagnetic flowmeter component 2 is used for flow monitoring, the fluid flows into the first connecting pipe 21 through the second branch pipe 7. The first connecting pipe 21 is sheathed with a lining 23. The lining 23 is made of corrosion-resistant, high-temperature-resistant and wear-resistant materials to prevent the induced potential from being short-circuited due to the metal measuring conduit wall. The excitation coil 25 in the installation groove 24 generates a constant magnetic field covering the cross-section of the measuring pipe through the pole shoe 26. When the conductive fluid flows in the measuring pipe, the magnetic field will exert a force on the charged particles in the fluid, thereby separating the positive and negative charged particles in the fluid and concentrating them on the pipe wall. On both sides of the pipeline, the sensing electrode 27 will detect the voltage waveform and measure it. The voltage is proportional to the flow rate of the fluid in the pipeline.

The turbine body 44, whose rotation speed is proportional to the flow rate, is converted into a periodic pulse signal by the sensor 45. The second header 46 analyzes and obtains The flow parameters are measured and displayed on the second display screen 47. The real-time data of flow monitoring is transmitted to the wireless transmission component 3 through the first interface 210 or the second interface 48. The data is uploaded to the system platform through the wireless communication unit 33 to realize remote monitoring by the staff. When the flow meter component on one side needs to be replaced or repaired, it is only necessary to open the valve on the branch pipe on the other side, open the passage and close the branch valve on the repair side, close the passage and switch the fluid delivery pipeline, and then the flow meter component on this side can be disassembled for maintenance and replacement.
