Grundfos VFS Analog Temperature Sensor

VFS 2-40L

VFS Grundfos Direct Sensors™ measure the temperature and the flow rate with a single measuring element. Based on the vortex principle, the sensor measures the flow rate by means of the pressure differences caused by the fluid turbulence occurring at the insert. Grundfos Direct Sensors™ can be used in aggressive media as well as in domestic water and thus are ideal for measuring the flow rate and the heat quantity in solar thermal and heating systems.

Features and Attributes:

• 2-in-1 flow and temperature sensor
• 5V stable power supply with general ratiometric signal output from 0.5 - 3.5V from flow min. to flow max.
• Composite body and insert which go inside a stainless steel pipe
• Works directly with RESOL® DeltaSol® MX and RESOL® DeltaSol® BX
• 3/4" analog NPT
