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.
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.
