Sensata Technologies has introduced a line of ultrasonic flow sensors designed to monitor liquid cooling systems in data centres operating AI workloads.
The industrial technology manufacturer stated that its FL Series provides non-intrusive monitoring to assist facility operators in identifying operational faults and maintaining computing uptime.

Experience unmatched clarity with a single platform that combines unique data, AI, and human expertise.
Cooling demands within data centres have expanded as facilities deploy high-density graphics processing units and high-performance computing hardware.
Sensata noted that precise circulation control is necessary to prevent thermal disruption: insufficient liquid flow causes hardware overheating and lowered processing speeds, while excessive flow wastes facility power and degrades overall cooling efficiency.
The hardware maintains flow rates of up to 400 litres per minute across both primary and secondary cooling circuits.
Featuring no moving parts and an IP65-rated enclosure, the units achieve a measurement accuracy within plus or minus 1% of full scale while maintaining a low pressure drop.
The ultrasonic mechanism delivers consistent readings despite fluid aeration or bubbles, supporting early issue detection and scheduled maintenance before unscheduled outages occur.
Sensata Technologies EVP and industrials president Alice Martins said: “As AI and high-performance computing place greater demands on data centre infrastructure, effective cooling is becoming increasingly critical.
“Sensata brings capabilities across the data centre environment, from thermal management to electrical protection and power management.
“The FL Series builds on that broader portfolio, giving customers reliable flow data to help them manage cooling performance and keep critical systems operating reliably.”
Engineered for coolant distribution units, chillers, and heating, ventilation, and air conditioning plant, the sensors function with both glycol mixtures and deionised water.
The system connects to programmable logic controllers and building management platforms using standard digital and analogue outputs.
Users can also configure the devices with optional temperature sensing alongside a selection of connection styles, enclosure materials, and communications protocols.
The product introduction broadens Sensata’s data centre equipment footprint across thermal control, power distribution, and electrical safety systems.
Sensata Technologies operates in 13 countries with a workforce of over 16,000 employees, supplying sensor and electrical protection technologies to the automotive, aerospace, defence, industrial, and commercial equipment sectors.
