FIELD: power industry.
SUBSTANCE: method of evaluation of mass concentration of oxygen in under pressure circuits with water heat carrier consists in sample withdrawing, cooling and throttling. Also measurement of mass concentration of dissolved oxygen is performed by an ampere-metre sensor. Pressure in the circuit and sensor is also measured. Further there is calculated mass concentration of oxygen. Notably, measurement of mass concentration of dissolved oxygen is carried out at temperature 41-50°C.
EFFECT: increased reliability of results of measurements of dissolved oxygen mass concentration in circuits under pressure with water heat carrier at maintaining continuity and immediacy of measurements.
