Grundfos Vortex Flow and Temperature Industrial Sensor with Cast Iron Flange

The VFI flow transmitter from Grundfos Direct Sensors™ is designed for industrial applications. The transmitter is based on the principle of vortex shedding behind a bluff
body.

The VFI transmitter is fully compatible with wet, aggressive media. The transmitter is based on MEMS sensing technology in combination with the corrosionresistant Silicoat® coating technology on the transmitter chip.

This makes the VFI transmitters very robust and ideal for pump integration and monitoring in harsh environments. The transmitter is supplied with a stainless steel flow pipe, available with flanges or in a threaded version.

VFI is a flow and temperature industrial sensor designed to be robust, accurate and easy to install. It uses our Silicoat® coating to be in direct contact with the media and provide stable signals.
