FIELD: food industry.
SUBSTANCE: ensuring a system of flow rate sensors for perception of a fluid medium flow indicative of strain in an aerosol generation system. The sensors system includes a sensitive circuit containing a sensitive resistor and a voltage output. The sensitive resistor is designed so that to enable detection of a fluid medium flow based on resistance measurement. The sensitive circuit is designed so that variation of the sensitive resistor resistance causes that of output voltage. The sensors system also includes a signal; generator designed so that to enable delivery of a control pulse signal to the sensitive circuit for the sensitive circuit power supply. Power is supplied to the sensitive circuit when the control pulse signal is high and is not supplied when the control pulse signal is low. The sensors system is designed so that enable operation in the first mode wherein no strain is expected or has not been detected (with the control pulse signal having the first frequency) and the second mode wherein strain is expected or has been detected (with the control pulse signal having the second frequency exceeding the first one).
EFFECT: ensuring an improved system of flow rate sensors suitable for aerosol generation.
