The Situation
The original requirement was to communicate Flow & Temperature information to their customer’s software system. Due to the small size of the installation the VFS fitted the application.

The Grundfos Solution
2 x VFS 5-100 dual output sensors have been used to provide the 4 signals for the control software.
Installation in the pipework in space, that is very limited for 2 sensors, was made possible for TES by our VFS sensors each having 2 measurements in the water stream.

The Outcome
As you can see from the picture below, the pipework as shown in section above, fits into a very small space in the unit. This created the need for small dual output sensor. The VFS fitted the bill perfectly.

VFS 5-100 & RPS 10bar


Stewart Winborn :

The VFS is an innovative sensor that I’d not seen from anyone else. It suited this very difficult application as it offered the 2 measurements we needed. After the initial installation challenge was overcome we are happy to consider all Grundfos Direct Sensor products for new products and applications.

Bryan Maddock :

Due to many tight pipe bends and a different signal to the standard previous used this was difficult for any sensor to satisfy the requirement. However the FVS 5-100 with solder connections eventually provided the solutions.
Cooling applications are very well suited to the GDS sensor.
