Use our online accumulator volume sizing calculator to determine optimal capacity.
Open Volume Calculator →For equipment where, due to cost or installation-space constraints, it is not feasible to install a piston‑type accumulator (servo cylinder) level‑monitoring device, when operating conditions require monitoring the energy stored in the accumulator (or the system), or when maintenance and servicing necessitate detecting the piston position within the piston‑type accumulator to measure the fluid level, an ultrasonic position‑sensing device manufactured and supplied by SCHWERLL can be employed. This device enables precise measurement of the piston‑side fluid level without disrupting the equipment’s operational status; the sensing is performed through a metal housing, with the metal wall thickness tolerating up to 35 mm on a single side.

This device enables precise measurement of the piston‑side fluid level without disrupting the equipment’s operational status; the sensing is performed through a metal housing, with a detectable wall thickness of up to 35 mm on each side. Its key features include:
1. Complete set supplied, including ultrasonic sensors, signal amplification and display units, coupling agent, and other components;
2. Signal detection is simple to operate, requiring no shutdown or special preparatory work;
3. It can be applied to hydraulic‑controlled accumulators in wind power systems for leak detection, to the commissioning and maintenance of hydraulic piston accumulators in hydropower applications, to energy monitoring of accumulators in valve control systems, as well as to blast furnace covers and potential‑energy recovery systems—any hydraulic control system that requires energy monitoring or emergency backup energy management.
