Automotive Testing Expo 2016
Sentronics launches two FlowSonic fluid flow sensors for the automotive testing and development market at the Automotive Testing Expo.
The two products are the latest example of race-bred technology crossing over into the wider automotive industry. The original FlowSonic range has been created for the fuel flow control regulations introduced to FIA Formula 1 and LMP1 (Le Mans Prototype) competition in 2014. The FlowSonic LF has been specially developed for the ultra-low fuel flow conditions found in the latest generation of road car engines. The FlowSonic HF is designed to measure the high fluid flows seen in heavy-duty industrial vehicle power-plants.
Both models offer laboratory-quality data in a package allowing portability between dynamometer and road. Advanced ultrasonics, a true 2,2 kHz update rate (for the LF), and fully digital internal processing are delivered. Data outputs include volumetric, mass, and cumulative flows, as well as running time, speed-of-sound, and diagnostics. The FlowSonic can accommodate a range of automotive testing flow rates, temperatures, vibration conditions, and fuel types. CAN, TTL pulse, and analog output formats are available. With no moving parts and the benefit of intensive F1 and LMP1 bench and track testing, the sensors’ performance is matched. Pricing is competitive with conventional fuel flow measurement equipment.
Since its formation in 2013, UK-based Sentronics has established a record of engineering high-level custom solutions based on its technology. In 2014, the company responded to a F1 engine supplier’s request to address measurement errors stemming from aliasing in the original FIA-homologated 1 kHz sensor by more than doubling the update rate. The resulting sensor was fitted to the winning car in the last four Grands Prix of 2015. Sentronics also helped an LMP1 entrant to overcome serious sensor issues caused by high fuel temperatures with its FIA-homologated FlowSonic Elite HT model, which is capable of running at 120 °C (continuous), 35 °C hotter than the original FIA specification. For the LF sensor, the company adapted its core technology to handle the ultra-low flow rates of modern road car engines.
Orders are now being taken for the production of the FlowSonic LF sensor for delivery within six weeks. The FlowSonic HF demonstration units will be available from early August. The company showcases the sensors at the Automotive Testing Expo 2016 in Stuttgart, Germany from 31 May to 2 June, booth 1040.
