Oil flow indicator
CEDASPE® SCFR2 checks the circulation of dielectric fluids in the cooling installations of electric transformers according to French standard NF C 52-122. The flow speed is indicated optically by an arrow that indicates the running (M) or the stoppage (A) of the circulation pump and electrically by electric contacts. It is based on the dynamic thrust of the flowing oil on a detection paddle placed inside; the dimensions of the paddle depend on the diameter of the pipe. An adjustment device allows the triggering point to be altered within certain limits, to adapt it to the real flow conditions.
