Grundfos VFS 5-100 Flow and Temperature Sensor (98463920)

Grundfos Direct Sensors, 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 with 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 many different applications.
