Accumulators, particularly accumulator systems, are required to deliver extremely high‑rate, instantaneous hydraulic flows when serving as power sources or providing auxiliary flow functions. However, measuring and controlling such transient ultra‑large flows is highly challenging. To address this, SCHWERLL has developed an integrated liquid‑side pressure‑line system with large‑diameter conduits, enabling precise control and distribution of high‑flow rates on the accumulator system’s liquid side.
