GEMS Flow Sensors
TE Instrumentation supplies GEMS flow sensors for continuous liquid measurement, visual flow indication and OEM flow monitoring. As exclusive GEMS distributor in the Netherlands, we support selection for machinery, cooling circuits, test equipment, HVAC and data-centre liquid cooling.
The correct flow sensor depends on the medium, pipe diameter, flow range, temperature, pressure, accuracy, permitted pressure loss, output and available installation space.
Clamp-on ultrasonic measurement.
Visual and electronic monitoring.
Low flow for OEM systems.
GEMS XFT clamp-on ultrasonic flow meter
XFT measures flow without opening the pipe. It mounts externally on compatible pipework and has no moving or wetted parts, avoiding additional pressure loss, contamination points and added leak paths. Depending on configuration, the series supports flow and pipe-temperature measurement, analogue outputs and Modbus RTU.
This makes XFT relevant to retrofits, OEM skids, utility circuits and rack- or CDU-based liquid-cooling systems. View official XFT product information.
RotorFlow flow sensors
RotorFlow provides immediate visual confirmation of liquid movement and, depending on the model, an electronic output for monitoring or control. GEMS also positions RotorFlow for data-centre liquid cooling and rack-CDU applications. View GEMS RotorFlow RFI.
GEMS FT-110 turbine flow sensor
FT-110 is designed for low liquid flows in compact OEM applications. It can be installed in different orientations and is available with different connections and ranges. This can suit cooling circuits, analytical equipment and integrated machinery after checking the medium and filtration requirements. View official FT-110 information.
Flow sensors for data-centre liquid cooling
Flow measurement in a Coolant Distribution Unit or Technology Cooling System confirms coolant circulation and helps expose circuit deviations. XFT supports non-invasive measurement, RotorFlow combines visual checking with signalling and FT-110 supports compact OEM loops. Explore the complete data-centre sensor architecture.
Flow measurement in semiconductor equipment
Flow sensors can monitor supporting utilities and cooling circuits in high-tech equipment. Selection must consider media purity, material compatibility, range and integration requirements. Explore our wider solutions for semiconductor equipment.

Frequently asked questions
When should I choose a clamp-on flow meter?
A clamp-on meter is useful when the pipe should not be opened, pressure loss and contamination must be avoided or a retrofit requires no additional leak point.
What is the difference between a flow sensor and flow switch?
A flow sensor normally provides a continuous measurement signal; a flow switch provides a switching output when a defined flow condition is reached.
Can GEMS flow measurement be used in a CDU?
GEMS positions several flow families for CDU and liquid-cooling duties. The configuration must be selected for the coolant, range, pipe and control strategy.
