The liquid circulation indicators Series CCL2 are designed to detect the operation of circulation pumps in cooling installations, in particular those of electric transformers, and are therefore particularly suited for detecting the flow of oil or water in piping, respectively by types CCL2-O, for oil, and CCL2-A, for water. The possibility of using them with other fluids and/or in other installations depends on the fluid and its compatibility with the materials used in the construction of the device and must therefore be looked into in every case.

The circulation indicators Series SCFR2 are designed to check the circulation of dielectric fluids, normally mineral oils, in the cooling installations of electric transformers. The dimensions, the assembly and all other characteristics are according to French standard NF C 52122.
