Have you ever worked on quantitative control for loading and unloading trains?
Thread Content
As the title says. The train has 58 carriages equipped with loading nozzles; it is planned to load 8 carriages at a time, with the loading process to be completed within 8 hours. May I ask what type of flow meter offers the best cost-performance ratio for this purpose?
Then one needs to choose based on what needs to be installed and the required measurement accuracy. Mass flow meters have the best measurement accuracy, but they are also the most expensive. Vortex flow meters, electromagnetic ones, and positive displacement types come next.
It’s necessary to understand the medium in order to choose the right measuring instrument!
A mass flow meter should be chosen. It offers better value for money.
