METHOD OF DIAGNOSING CROSSINGS OF MAIN PIPELINES STATE AND SYSTEM TO THIS END Russian patent published in 2011 - IPC F17D5/00 

FIELD: machine building.

SUBSTANCE: linear deformation magnitudes D1(t), D2(t) of pipeline crossing at time t are measured to monitor compliance of measured values with appropriate ranges of tolerable values (Dh1…Db1), (Dh2…Db2), and, in case at least of measured value D1 (t) or D2(t) falls beyond appropriate range of tolerances, dangerous state is taken to exist. Proposed system comprises m strain gages, m ADCs, microprocessor and means of communication with dispatcher station on each pipeline crossing. Note here that axes of strain gages are directed along pipeline whereon they are mounted. Output of each gage is connected via appropriate ADC to microprocessor and the latter is connected to means of communication with dispatcher station (m= 1,2,3…).

EFFECT: higher reliability of control.
