Heinrich Koppler founded KSR-KUEBlER in Stuttgart, Germany, in 1962. He developed the first magnetic switch for elevators, and Copro's product became a hit. In 1965, Koplesen invented the liquid level float switch based on magnetic theory. The launch of this product, but also in the liquid level measurement and control field set off a revolution. And since then, the liquid level sensor, bypass type liquid level meter has been published, but also won the market's wide praise. Liquid level measurement and control products based on the principle of magnetic coupling have therefore become the main product series in the history of Cople.
