The FLOW-meter measures the fuel consumption of models with turbines, which are made available for transmission on the telemetry return channel of the respective remote control system. The model pilot is thus always informed about the current consumption/tank level.

Depending on the remote control system, alarm thresholds (reserve, turbine OFF) can be set in the transmitter or in the FLOW meter. The consumption/tank level can reset via a separate servo channel - so displaying the actual consumption/tank level would not be a problem even after a so-called "taxi tank" has been disconnected after the start phase.
