Burkert, of Irvine, Calif., recognized many years ago the benefits of building flexibility into its components. They offer a “Turn & Lock” inline flow control system designed for reduced installation costs, easy maintenance and a reduced number of total control components. “Turn & Lock” describes the installation method of this complete and coordinated system, consisting of interchangeable electronic modules, which lock into an inline magnetic sensor rotor fitting by a quick quarter-turn locking mechanism.
