FIELD: agriculture, systems monitoring temperature and level of products stored in isolated reservoirs. SUBSTANCE: one-time calibration of readings of temperature sensitive elements is carried out. These readings are used to correct next current values of difference. Spread of readings of temperature sensitive elements is taken into consideration. Preliminary measurement of difference of temperatures is performed between upper point located in air column above product and lower point located in product. This difference is compared with chosen threshold to check conditions of obtainment of authentic measurement. EFFECT: increased authenticity of method. 1 dwg
