Keeping track of hydraulic fluid and lubricating oil levels in large machines usually requires a technician navigating around a machine, viewing a sight glass at each reservoir, and noting results on a clipboard or handheld device. A high-tech approach would be to equip each reservoir with some sort of transducer that would send results to a central processor with wireless communication. Although this solution may be the most practical in the long run, it requires a substantial initial investment, making it impractical for many manufacturing plants.
Luneta LLC, Tulsa, Okla., offers a solution that provides centralized oil level monitoring without the expense of sophisticated automated electronic systems. The Hub is a multiport adapter that a user connects to oil level sight glasses, drain valves, quick connects for attaching filtration equipment or taking fluid samples, etc. In addition to four lateral ports, the Hub features a recessed oil sampling port to prevent inadvertent impacts. It is intended for equipment with limited or inaccessible fluid port locations.
The Hub is designed for easy installation with zinc-plated-steel back-plate that threads easily into a reservoir port. An aluminum body slides onto the back plate and can be adjusted at 45-deg. intervals for convenient viewing. It comes with a 12-in. long, ¼-in. pilot tube with two 1-in. and two ¾-in. NPT lateral ports and protective caps for when the Hub is not in use. Versions are also available with BSPP ports and 1¼- and 1½-in. NPT lateral ports.
