VAF Instruments ProFlow Sliding Vane Flow Meter

VAF Instruments introduces the ProFlow positive displacement sliding vane type liquid flowmeters, designed for continuous metering applications involving oil-like liquids, with a specific focus on accurate fuel oil consumption measurement. ProFlow flowmeters feature a simple, rugged design with a limited number of nearly frictionless internal moving parts, ensuring minimal wear and a prolonged lifespan. This design also eliminates the need for mechanical seals, thereby reducing maintenance requirements and preventing potential leakage of process liquids into the environment. These flowmeters are driven by the process liquid itself, making them suitable for locations without a power supply. The high accuracy of the ProFlow flowmeters, reaching down to 0.2%, along with a repeatability of 0.05%, remains unaffected by process pressure, temperature, mechanical pipe strain, or liquid turbulence. This unique attribute eliminates the necessity for straight inlet and outlet pipe segments.

Operating on the sliding vane principle, the ProFlow flowmeter employs a rotor with pairs of vanes housed in a specially shaped chamber. The incoming liquid forces the rotor to rotate, while an internal magnet transmits these rotations to an electronic counter. An optional electric pulse output is also available for remote totalizing or flow data processing. ProFlow flowmeters offer features like high capacity, design simplicity, and accuracy regardless of external factors. They are suitable for a range of hydrocarbon liquids, including medium and heavy fuel oils, as well as lubricating oils. These flowmeters come in various models catering to different capacities and liquid types, making them versatile and reliable solutions for accurate flow measurements across diverse applications.
