High flow coolant measurement

Cooling and lubrication systems play a major role in engine efficiency, and our FlowSonic® HF (high-flow) meter is designed to measure high-volume coolant and oil flows in all vehicle types, along with fuel consumption in heavy-duty vehicle commercial and industrial vehicle powerplants.

Easy installation on test bench or vehicle

The FlowSonic® HF offers significant advantages in accuracy, convenience, robustness and correlation of laboratory with road test results over conventional measurement equipment. As is synonymous with the Sentronics range of ulltrasonic products, the HF is compact for convenient installation and placement.

Inline flow path for high volumes

Featuring an inline flow path, the FlowSonic® HF is ideal for handling volumes of coolant flow up to 500 litres per minute.
