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 utilizes MEMS sensing technology in combination with a novel packaging concept using a corrosion-resistant coating on the MEMS sensor element. This makes the VFS sensor very robust and ideal for many different applications.
Compatible with Resol controls sold purchased on Solarthermal.com which accept flow and pressure sensors (RPS and VFS).
Please note: Grundfos, the manufacturer, does not include the cable in this kit.
