The SDMKR reversible flow device developed by STAUFF is for the rapid and accurate monitoring of hydraulic components and systems. The design allows the simultaneous measurement of flow, pressure, and temperature, letting maintenance personnel determine the performance of pumps, motors, valves, or cylinders, as well as of complete systems. The portable flow devices are integrated in the hydraulic circuit only for the duration of the system test. They are equipped with BSP connection threads on the input and output, and can be installed in both pressure and return lines.
The testers include a flow meter with a visual display and a built-in thermometer, as well as a loading valve. The loading valve makes it possible to safely increase the working pressure gradually and continuously up to 420 bar (6 ksi) to provide a realistic simulation of normal machine operation. Two integrated burst discs act as an internal safety mechanism, effectively protecting the device against accidental over-pressure. When the maximum pressure in the hydraulic system is exceeded, the discs break and the oil is transported through a bypass.
