VFS 20-400, Grundfos Flow Meter, 1 1/4"NPT, 5.28 - 105.7 GPM

Technical overview

Grundfos Direct Sensor™, type VFS, is a series of combined flow- and temperature sensors (two-in-one) based on the principle of vortex shedding behind a bluff body. The VFS sensors are designed for high-volume production and are fully compatible with wet, aggressive media. The VFS sensor utilises MEMS sensing technology in combination with a novel packaging concept using corrosion-resistant coating on the MEMS sensor element. This makes the VFS sensor very robust and ideal for high-volume OEM applications. VFS sensors are available for flow ranges of 1-12, 1.3-20, 2-40, 5-100, 10-200 and 20-400 l/min.
