Piston displacement energy monitoring system
Schwerll Company provides a stable and reliable piston displacement monitoring system for piston accumulators and their associated systems. Through displacement sensors installed on the gas side and externally, the system monitors the liquid level within the piston accumulator and calculates flow rate. This allows for monitoring of the gas energy within the piston accumulator or system, ensuring the accumulator's operating status. Energy monitoring is especially crucial when the accumulator serves as a necessary power source for the system.

High-pressure bellows accumulator
Compared with rubber diaphragms and metal pistons used as internal gas–liquid separation elements in accumulators, metal bellows offer superior gas tightness. For pressurized nitrogen service, their intrinsic nitrogen permeability is virtually zero. Leveraging this property, high-pressure metal‑bellows accumulators are well suited for applications where replenishing nitrogen is challenging, such as subsea ROV systems, underwater unmanned vehicles, hydraulic control systems within spacecraft cabins, and ultra‑compact vibration‑damping accumulators in vehicles.

Oil–gas mixing tank with liquid-level monitoring
In medium- and low-pressure applications, oil–gas mixing tanks are used to control electro‑hydraulic servo systems, with water and air as the working fluids. Air is pressurized by an air compressor system. To ensure the reliability of the oil–gas mixing tank’s control, proper volumetric matching calculations must be performed, and a liquid‑level monitoring system should be installed.
