Straight pipe section of the flow meter

The straight pipe sections installed before and after the flow meter can ensure that the fluid flow state in the pipeline is uniform, which does not directly affect the measurement accuracy of the flow meter, achieving good measurement results.

Quickly open the blind plate.

The quick-opening blind plate is a fixed quick-opening device set at the pipe opening for cleaning, unblocking pipelines, and inspecting and clearing containers.
