Description

A Water Meter Test Bench is equipment that can be built from a simple and completely manually operated machine to the highest levels of high tech, designed with automatic controls and IT support. We can design and make them all.

Each project is discussed with the client and tailor-made to fit both the technical needs and budget constraints.
