Digital volume piston accumulator LEDVPA series

The LEDVPA series is a floating piston accumulator equipped with an integrated LVDT (linear variable differential transformer) to monitor piston position. The LVDT is mounted inside the driving fluid chamber between the cylinder’s cap end and the piston. As the piston extends or retracts, its motion causes displacement of the LVDT and produces an analogue signal directly proportional to the piston displacement.

The piston location, and hence the total sample volume in the accumulator can be accurately measured and displayed. The digital volume display can also be connected to a computer to enable continuous communication and logging. This accumulator module is particularly suited for core flooding experiments as it grants continuous awareness of fluid sample reserves.
