WebIdeal for monitoring pump performance and media flows in hydraulic systems. Flows up to 150 GPM (568 Lpm). Pressures up to 6000 PSI (414 bar). Use these flow meters to setup, adjust and test hydraulic pumps, motors, cylinders and more! The only way to test a pump and motors safely and effectively is to use a flow meter. WebAs in all hydraulic systems, more pump oil will flow to the branch with the lightest load. Bank valve handles can be modulated to equalize the flow to each branch. When individual 4-way valves are used in each branch, flow control valves may be installed in the branch circuits and adjusted to give the flow desired in each branch.
