In 1947 two brothers, Hugo Torbard and Tage Torbard, founded Elektriska AB Eletta, the company known today as Eletta Flow AB. Initially the company, which was based in Stockholm, produced different kinds of electrical equipment.

These early flow monitors proved successful and in the early 1950:s they were launched on the market. From a technical point of view the flow monitors were based on the differential pressure principle and equipped with an orifice plate. That basic design, although much improved, is still the foundation of more than 90 percent of the flow monitors produced by Eletta.

Over the years the range has been expanded with new materials, larger process connections and different out-put signals. Eletta nowadays is a manufacturer and developer of very robust differential pressure flowswitches and monitors.
