Grundfos Direct Sensors™ Case Stories
The following case stories represent a reference list of applications where our Grundfos sensors have been implemented with great success.
We are constantly working on updating this list with focus on new applications that we have gone into and are not yet shown here. For further questions about these or other applications and about our sensors, please, don't hesitate to contact us.
To see the case stories, just scroll down this list and click on the photo or text of which ever user case is of interest to you. You will then be redirected to the User Case's webpage. If you would like to search for some more general Grundfos cases, please go to the grey ribbon and select cases from there. You have multiple selection and search options there.
Medical cooling by Beehe with Grundfos Direct Sensors™
To measure the flow rate of different cooling loops in Magnetic Resonance Cooling System Beehe needed a flow sensor with high accuracy, low cost, small size, analogue output and without moving parts inside. Grundfos VFS series flow sensors combines all the requirements described above, so Grundfos was chosen at the beginning of selection.
VFS & RPS sensors in the new Engel e-Flomo
For all three necessary measurements in the system, Engel uses Grundfos Direct Sensors™. The main advantage of the sensors is that they are 2in1 sensors. This means that the VFS is a vortex flow and temperature sensor, able to measure up to 120 °C; while the RPS is a relative pressure and temperature sensor, with the same temperature measurement range.
Reisner Chillers & Grundfos Direct Sensors™
Together with Klaus Reisner and his team our sales engineers Sebastian Strang and Walter Steckenreiter have been involved in the selection of the suitable sensors. This is how the ideal Grundfos pump package for their chiller systems was selected and integrated into the system solution.
FlowCon Sensor - market standard for solar heatmetering
Sensor in state of the art compact boiler module
The mix of the Grundfos Pump Circuit and Grundfos´ Vortex Flow Sensor has resulted in the Multipurpose IWC, which saves cost through elimination of solitary temperature sensors and enables more compact boiler systems. The integration of a temperature sensor enables better control of the burner and lowers the power consumption.
By using the VFS it is possible to achieve faster and more accurate response to hot water consumption and since the VFS is a steadystate flowsensor it is possible to operate on the hot water side to increase hot water efficiency without any clogging or drift over time.
Trigas Fl manifold system using VFS
The sensors are integrated in the return to measure the real system temperature in each return. This installation makes it also useful to measure the flow, because a break of the piping can be detected by the flow sensor.
The use of the vortex flow sensors VFS 1-12 QT and VFS 2-40 QT enables TrigasFl to offer a more progressive solution to their customers. A flexible, extendable and robust manifold system is the result of using standard parts.
SINGLE Temperature Control Systems
The advantages of the Grundfos Direct Sensors™ could be used in several ways at Single. The combination of flow and temperature in one unit enabled Single to integrate the sensor also in crowded systems. The sensor principle without moving parts assured reliability and robustness in harsh environments and the competitive price makes it possible to integrate sensors also in low cost temperature control systems.
Since March 2006, Single has been a customer for not only pumps but also for the Grundfos Direct Sensors™. The sensors have been integrated in different other applications at Single during the last couple of years.

IPG Burbach cooling system for laser installation
Grundfos Direct Sensors™ for the integrated cooling modules:
For two years, IPG Laser is also using Direct Sensors™ of Grundfos to measure pressure and temperature in their system. Background: The integrated laser cooling module is placed inside the cabin. The laser protection class of the cabin doesn’t allow connecting external sensors.
Sensor improves the reliability of home booster
One such requirement in the UK market is low water pressure in homes, businesses and buildings. Many modern appliances such as Combi-boilers require a minimum pressure to operate. The Home booster was designed to overcome this in areas where the mains pressure is subject to fluctuations due to location, age of water infrastructure and potential for mains leakage.
SINGLE Water Distribution System
The VFS 1-12 QT and VFS 2-40 QT was the ideal solution, because of the possibility to integrate the cylindrical flow pipe into the brass manifold and then mount the sensor with an easy clip connection.
Ecotherm DPI solution for heating
It is necessary to control the clogging because of the aim of ECOTHERM to offer the highest efficiency in their systems.
The DPI was integrated in several applications with high reliability and extreme low failure rates. The implementation in the heat exchanger was therefore easy and is running without any complaints.
VFS sensors keep APC by Schneider Electric systems cool
As a part of the control system, we monitor several sensors and adjust the cooling units performance to ensure stable inlet temperatures to the IT equipment. A performance point that we relay to the end user is the actual cooling capacity of the unit.
VFS in PAW systems
Later on a further Grundfos development based on the VFS 2-40 was launched. Instead of a using a composite pipe the sensor could be integrated into a metal body, which was again a breakthrough for PAW as they could – following their core-competence - design there own armature to fully integrate Grundfos sensor solutions in the most cost-efficient way.

Flow control for Industrial Wash and Clean
Since KSN Industry A/S is a make to order company, then the number of sensors which they purchase varies a lot based on the type and size of the system build. But the VFS Sensor has become an integrated part of many of their systems today where it helps KSN Industry A/S save water, energy and delivers clean parts in a controllable manner to it’s customers.

dp for Flow controlled Pumps
As the idea behind an E-pump is to adjust the speed of the pump to the current need, the pump needs to get a feedback from a sensor concerning the condition of the system. E.g. if we set the pump at a predetermined pressure, the sensor will feed this true status of the system back into the pump and thereby vary the speed, to keep the constant pressure.
The most used type for circulating pumps is differential pressure sensors, due to their reliability and cost-performance. Incorporation of differential pressure sensors in the pump systems reduces the energy consumption considerably and increases pump performance.
