Advanced Flow Measurement Technology

FlowSonic flow meters employ the ultrasonic time-of-flight measurement method. This method of flow measurement has numerous advantages over other technologies, particularly in cases where the flow meter must be mounted on a vehicle.

Accurate and Repeatable

With accuracy levels of up to +/- 0.25% of reading and repeatability of +/- 0.05%, the FlowSonic delivers the quality data needed for precision measurement of fuel (and other fluid) flows in industry or motorsport.

Compact Yet Robust

With a dry weight of just 330g and volume of 260cc, the FlowSonic installs as easily on a vehicle as a test bench. Yet it is strong enough to perform reliably in the harsh environment of a Formula 1 or LMP1 race car. The solid-state design minimises pressure drop and eliminates the risk of engine damage.

Multi-Fuel Compatibility

The FlowSonic can be used with virtually any kind of fuel, from pump petrol and diesel to racing blends and ethanol, methanol, or bio-diesel alternative fuels. The HF model is also compatible with water, other engine coolants, and selected oil types.

High-Speed Measurement

Up to 2.2k entirely independent flow measurements per second – the fastest rate in the industry – ensure accuracy under all operating conditions and provide an unparalleled view of dynamic flow behaviour, even recording individual injector pulses.

Configurable Output Formats

The FlowSonic offers data communication options to suit almost any test system, with CAN, digital TTL pulse, and analog outputs all available.

Internal Data Processing

The FlowSonic employs proven proprietary circuitry, firmware, and software to convert raw data into key measures including volume flow and mass flow, plus a wide range of diagnostic and security functions.
