FIELD: measuring equipment.
SUBSTANCE: invention relates to the determination of a coolant (water) flow in a technological channel (TC) of a reactor installation (RI) of RBMK-1000 type. The device comprises a pressure sensor installed in the TC of the RBMK-1000 unit, a rack of a measuring and computing complex (MCC), a personal computer. The pressure sensor is an excess pressure strain gauge transducer based on a sapphire-titanium membrane, which is capable of proportional conversion of the coolant pressure into an electric DC output signal. The MCC rack supplies pressure sensors with a direct current of 1.5 mA. The personal computer controls the MCC rack and registers output signals of the sensors with recording on the storage medium and subsequent conversion of data into Ethernet format for the transmission to the information-measuring system "SKALA-micro", in which the coolant flow is calculated according to the differential pressure at the ADMS in TC when using the ADMS carrying capacity data from channel-by-channel data base of the IMS "SLAKA-micro". The device is designed to continuously monitor the coolant flow in the technological channel of the reactor installation of RBMK-1000 type.
EFFECT: increased accuracy of recording the flow rate of the coolant in the technological channel of the reactor, the triple reserve for exceeding the pressure of the coolant of the designed value, increased operating life of the pressure sensors.
