Flow and temperature sensor
10/11/2026
Parker Hannifin has launched the SCVOT2 vortex flow and temperature sensor, a new monitoring solution designed to support the growing adoption of liquid cooling technologies in data centres.The sensor combines flow and temperature measurement within a single device, providing real-time monitoring for liquid cooling systems used in high-performance computing environments. Parker said the SCVOT2 has been developed for modern cooling architectures, including direct-to-chip cooling and secondary loop applications, and is intended to help operators manage thermal performance and improve energy efficiency.
The launch comes as increasing use of artificial intelligence workloads and high-density computing systems drives higher power consumption at rack level, prompting data centre operators to adopt liquid cooling technologies to maintain stable operating temperatures.

According to Parker, the SCVOT2 enables continuous monitoring of coolant flow and temperature, allowing operators to verify heat removal performance, optimise coolant distribution and respond to changing thermal demands.
The sensor uses a vortex measurement principle with no moving parts, a design intended to minimise wear and reduce maintenance requirements over time. Parker said the technology also delivers low pressure loss, supporting efficient coolant circulation within cooling loops.
Designed for data centre cooling environments, the SCVOT2 supports water and water-glycol mixtures with viscosities up to 15 cSt. The device is rated for operating pressures of up to 16 bar and can withstand pressure shocks of up to 100 bar. It also supports applications with fluid temperatures reaching 125°C.
Beyond monitoring flow rates, the integrated temperature sensing capability is intended to improve control strategies and simplify diagnostics by providing multiple measurements from a single installation point. Parker said the sensor can help identify conditions that may affect system reliability, including reduced coolant flow, thermal excursions, air entrainment and early signs of component wear.
The SCVOT2 is designed for use throughout liquid cooling infrastructure, from rack-level secondary loops to systems supporting facility-side heat rejection. By combining sensing functions into a single unit, the device can reduce component counts and simplify system commissioning.
The introduction of the SCVOT2 also expands Parker’s SensoControl product portfolio and reflects the company’s growing focus on thermal management technologies for the data centre sector. The sensor complements other products in Parker’s liquid cooling offering, including quick couplings, manifolds, hoses and valves used in cooling system installations.
