The OTC 4277 provides unparalleled accuracy in testing hydraulic flow circuits from 4 to 54 gpm for industrial and agricultural machinery. With its fluid filled gauges that dampen vibration and precisely manufactured components, it can measure flow accurately within 4% of full scale. Due to its inner pass system, which includes extra burst discs, over-pressure conditions won't lead to hydraulic fluid spills and the components can accommodate bi-directional flow, reading flow in one direction.
