Product description
VFS Grundfos Direct Sensors can be used in both aggressive media and domestic water, making them ideal for measuring flow and heat rate in solar thermal systems and heating systems.
Features:
- One sensor, two measured quantities
- Incl. mounting, insert and connection cable
- Fast and accurate measurement through direct liquid contact
- No moving parts - no mechanical wear and tear
Applications
FS Grundfos Direct Sensors measure temperature and flow with a single measuring element. Based on the vortex principle, the sensor measures the flow rate through the pressure differences caused by the turbulence of the fluid at the insert.
