As an FIA Formula 1® homologated product and used by all teams on the grid, the FlowSonic® Sport is designed to measure on-vehicle fuel consumption accurately for teams consumption regulation compliance and analysis for race strategies.

Fast 2.2 kHz Measurement Rates for Dynamic Flows
The FlowSonic® Sport ultrasonic fuel flow meter features patented techniques for low latency enabling real-time, precision flow measurement. To accurately determine fuel consumption in race vehicles, Sentronics employs ultra-fast bi-directional flow measurement technology. This is crucial as reverse flow events occur under harsh braking conditions.

Compact Design for Simple Installation in Race Vehicles
Engineered for motorsport applications, the FlowSonic® Sport is lightweight and compact. With measurement accuracy unaffected by product orientation, the Sentronics ultrasonic fuel flow meter can be installed for convenient fitment and submerged within race vehicle fuel tank.
