13. Piping should be accurately aligned and of correct length The high pressure body of the flow meter can withstand shock and flow pressure pulsation Piping should be firmly supported by external mounting brackets both upstream and downstream of the meter to avoid any pipe flexing actions that could reduce meter life If the flow meter inlet or outlet is rigidly mounted and the opposing port is connected to flexible hose the end connected with the flexible hose must be rigidly mounted Use Teflon tape for sealing NPT fitting Install a union near the inlet or outlet of the meter to facilitate quick and easy meter removal and inspection during periodic maintenance procedures Mount the meter either horizontally or vertically flow arrow pointing to either side or straight up If the meter must be mounted inverted special inverted scales are available Verify the fluid is traveling in the direction of the flow arrow see Figure 1 on page 5 Systems that do not have filtration should be equipped with at least a 200 mesh 74 micron filter Most hydraulic systems already have much finer filtration The meter will allow particulates to pass that would jam most valves and flow controls Dirt ferrous metal or sealing agents may lodge and cause malfunction If the meter is jammed at a fixed position follow cleaning and maintenance instructions Do not use thread locking compounds as thread sealant Do not install the flow meter near turbulence pro
