To measure the flow rate of circulating water, with a pipe diameter of 1400 mm, what type of flow meter should be used?

If the straight sections before and after are required to be 20D, how should they be installed? I hope fellow sailors can help think this through; those with experience, please share your insights.
Hehe, I haven’t heard of it, nor have I seen it. I think it definitely can’t be like that
Use an Anubaa flow meter! The Anubaa flow meter (also known as the bell-type average velocity tube flow meter and Tobia tube flow meter) belongs to the differential pressure type of flow meters. It uses the principle of a pitot tube to measure the pressure difference between the dynamic pressure upstream of the barrier and the static pressure downstream, thereby enabling the measurement of flow rate. The pipe diameter measured ranges from DN20 to DN12000. The Aoniuba flow meter is primarily used for measuring various types of energy in industrial processes, such as liquids, fuel gases, steam, and gases, and it features high stability and repeatability.
An insert-type electromagnetic flowmeter should work
Use plug-in vortex flowmeters, ultrasonic flowmeters, and plug-in electromagnetic flowmeters.
Thank you! For insert-type electromagnetic flowmeters, which brand offers the best calibration services? I just saw some cloned versions; I need a model with a 30D diameter, but that’s impossible to find. Is there any model that requires a shorter straight pipe section?
Measurement of large-diameter circulating water flow: electromagnetic (not necessarily insert-type, inexpensive), multi-channel ultrasonic (insert-type). Ainuba-type devices are prone to gas accumulation, which affects measurement accuracy; try to avoid using them.
Large-diameter electromagnetic flowmeters are also expensive; ultrasonic flowmeters (flange type) could be an option as well. In any case, neither of them is cheap. But considering that the pipes are over a meter in diameter, it’s not some minor project, so the money that needs to be spent must be invested
An external clamp-type ultrasonic flow meter is convenient to install; a VeriFlow meter can also be used
To measure the flow rate of circulating water, if trade metering is not required, there is no need to choose expensive products. Insertion-type turbine flowmeters can fully meet the requirements. Don’t choose the most expensive one; just pick the right one.
The bundled ultrasonic flow meter is highly recommended. It offers an especially good cost-performance ratio when used in applications with large pipe diameters: lol :lol :lol
If it’s just circulating water, the A’niu target flow meter is the cheapest. Other types are rarely used for such a large caliber.
I’m using a elbow flow meter, but I’m not sure if its accuracy will meet the requirements!
