Product Description

CONTOIL VZO 25FL

The CONTOIL VZO 25FL is a mechanical ring piston flow meter designed for accurately measuring the consumption of heating oil (light/extra light). It operates on the positive displacement principle, ensuring high precision across a wide flow range. This meter features a robust construction and a mechanical roller counter display for direct volume reading. The flanged connections (FL) facilitate easy installation in pipe systems. It is commonly used for monitoring fuel consumption in burners, boilers, and small industrial applications.
