Vortex flowmeters can be widely used in pipelines of various sizes—large, medium, and small—to measure the flow rate of compressed air, saturated and superheated steam, natural gas, and various other fluids. They can also function as flow transmitters in automated control systems, offering advantages such as safety, stability, and a long service life. Below, the technical staff from the manufacturer will explain in detail to our users what key points need to be considered when installing and using vortex flowmeters for measuring steam. 1. There must be sufficient straight pipe sections upstream and downstream. If there are two 90 degrees on the same plane upstream of the sensor installation point. For elbows: the upstream straight pipe section should be ≥10D, and the downstream straight pipe section should be ≥8D. The control valve should be installed more than 8D downstream of the sensor; if it must be installed upstream of the sensor, the straight pipe section upstream of the sensor should be at least 20D long, and that downstream should be at least 5D long. 2. Choose the installation location and environment appropriately. Avoid strong electrical equipment, high-frequency devices, and powerful power switching equipment; stay away from sources of high heat and radiation, as well as areas with intense vibrations and highly corrosive environments. At the same time, ease of installation and maintenance should be taken into consideration. 3. Vibration reduction measures are taken for the pipelines. Sensors should be installed as far as possible away from pipes with high vibration levels, especially lateral vibration. If installation is unavoidable, vibration reduction measures must be taken: pipe fastening devices should be installed at 2D positions upstream and downstream of the sensor, along with vibration damping pads. 4. The piping upstream and downstream of the installation point should be concentric with the sensor, and the coaxial deviation should not be less than 0.5DN. 5. Installation of sensors in vertical pipes. When measuring gas flow, the sensor can be installed on a vertical pipe, with no restriction on the flow direction. If the gas under test contains a small amount of liquid, the flow direction of the gas should be from bottom to top. When measuring liquid flow, the flow direction of the liquid should be from bottom to top: this prevents the weight of the liquid from being added additionally to the probe. 6. Installation on horizontal pipes is the most common method for installing flow sensors. When measuring gas flow, if the gas under measurement contains a small amount of liquid, the sensor should be installed at a higher position in the pipeline. When measuring liquid flow, if the liquid being measured contains a small amount of gas, the sensor should be installed at a lower position in the pipeline. 7. Inversion of the sensor in a horizontal pipeline. This installation method is generally not recommended. This installation method is not suitable for measuring ordinary gases or superheated steam. It can be used to measure saturated steam, and is suitable for measuring high-temperature liquids or in situations where the pipes need to be cleaned frequently. 8. The sensor is installed on the side of the horizontal pipeline. Regardless of the fluid being measured, the sensor can be installed on the upper side of horizontal pipes, especially when measuring superheated steam, saturated steam, and low-temperature liquids. If conditions permit, side installation is preferable, as it reduces the impact of the fluid temperature on the amplifier. 9. Selection of pressure and temperature measurement points. Depending on the measurement requirements, when it is necessary to measure pressure and temperature near the sensor, the pressure measurement point should be located 3–5D downstream of the sensor, while the temperature measurement point should be located 6–8D downstream of the sensor. 10. Installation of sensors on insulated pipes. When measuring high-temperature steam, the insulation layer shall not exceed one-third of the height of the support. Flow metering is one of the components of measurement science and technology, and it is closely related to the national economy, national defense construction, and scientific research. Doing this work well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today’s era of energy crises and increasing automation in industrial production, the significance and role of flow meters in the national economy have become even more evident.
