The VSE VS02EPO12 is a high-precision gear flow meter designed for accurate and reliable measurement of a wide range of liquids, including abrasive and poorly lubricating fluids. Part of the renowned VS series from VSE Volumentechnik, this model is built with a robust housing and high-quality internal components, ensuring long service life even in demanding industrial environments. It operates on the positive displacement principle, where two precisely matched gears rotate within a housing, trapping and transporting a known volume of fluid with each revolution. The integrated EPO12 preamplifier provides a clean, high-resolution square wave pulse output, making it easy to integrate with PLCs, controllers, and data acquisition systems for applications in hydraulics, lubrication technology, and process control.
