How is the overflow volume of a storage tank measured?

When the tank is about to be filled, some of the liquid flows out through the overflow pipe. The owner requests that the amount of overflow be measured using a flow meter. What kind of meter do you all use for this purpose? In chemical processing units, instruments used for measuring flow rate generally require the medium to fill the pipeline; however, the medium flowing out of the overflow pipe cannot initially fill the pipeline, resulting in inaccurate measurement values. I am seeking advice from experts – it’s urgent, and the sooner the better. Thank you!
It’s an unreasonable request; do not use a level switch or level transmitter with an alarm for tank overflow protection
Reply to 2# hzh04213: The medium in the storage tank is distilled condensate that enters the tank, while the excess medium is collected in another tank.
The overflow pipe can be designed with a U-shaped bend, with the surface located below the bend; wouldn’t that ensure that the medium fills the entire pipe?
Reply to 4# zyzs: The U-tube ensures the tube is fully filled; what is the maximum flow rate possible? How is this quantity determined and measured?
Add a buffer tank to the U-tube, and select an appropriate flow meter
Add a bend behind the overflow tube to ensure the flow meter is filled. It is recommended to use positive displacement flow meters; of course, the appropriate material also needs to be chosen based on the properties of the medium. http://www.shakic.com/cp/OVAL%20LNV%20oval%20gear%20flowmeter.htm
Reply to 1# Plum Blossom Fragrance: It might be a good idea to try making a U-shaped bend and installing the flow meter at the bottom of that bend, so as to ensure that the pipe is always full. This is just my personal opinion, for your reference.
