LFY-710 Catheter Flow Tester
It is suitable for the measurement of the flow velocity of water flowing through the catheter in a medical catheter under a constant static pressure head. It can also be used to determine the flow velocity of other rigid or semi-rigid fibers that are tubular materials and the water flowing through the catheter.
Invention patent: ZL 2015 1 0405837.9
The main purpose
It is suitable for the measurement of the flow of water flowing through the catheter under a constant static pressure head, and it can also be used to determine the flow of other rigid or semi-rigid fibers in the form of a tubular material.
