In addition to the requirements for straight sections before and after the flow meter, these rules also apply in front of control valves, etc； It is also important to note when installing on horizontal and vertical pipes: 1. Differential pressure throttling type instruments (orifice plates, venturi tubes, Anemometers, pitot tubes, nozzles, etc.). Horizontal pipes are the best installation location, but vertical pipes are not prohibited. 2. Rotary flow meters are recommended to be installed in vertical pipes, with the fluid flowing from bottom to top. 3. It is best to install electromagnetic flowmeters in vertical pipes to ensure full flow within the pipe, from bottom to top. 4. Vortex flowmeters work for all of them. But a full pipe of fluid is required. 5. Ultrasonic flowmeters have no limitations. 5. Volume and turbine flowmeters can be used in both vertical and horizontal pipes. 6. There are no limitations on the mass flow meter. Dear sea friends, share your successful experiences!
2. Rotary flow meters are recommended to be installed in vertical pipes, with the fluid flowing from bottom to top. There are products with a horizontal installation, whose internal structure is vertical. 5. Ultrasonic flowmeters have no limitations. It also needs to be filled with pipes
Reply to 1# kevinyu: Could the original poster please share some calculation sheets for the Aoniuba and Weiliba flowmeters? I’d like to learn from them as well. shan*jidian02@163.com Thank you
For large-diameter horizontal straight pipes in circulating water systems where flow rate measurement is required, what type of flow meter should be used? Could that expert give some advice?
Just my personal opinion – devices such as orifice plates, average velocity tubes, wedge-type meters, mass flow meters, turbine meters, etc., are better installed horizontally； Electromagnetic, vortex, thermal vertical ； The metal rotor sometimes needs to be vertical and sometimes horizontal. . Of course, this installation is related to various factors such as the medium; for liquids, it is generally recommended to have them in a horizontal position, while gases can be placed vertically. . If there are any mistakes, I ask the experts to correct them. . Thank you

I have some questions and would like to ask everyone: What is the best type of flow meter for measuring gases, both non-corrosive and corrosive? Are the measured values the flow rate under standard conditions (after conversion) or the actual flow rate?
