The metrotype system of digital recording and telemetering

摘要

THE YEARS since the war have been highlighted by ever-increasing costs of production. With such a condition existing, the need for automatic devices to monitor and control processes becomes increasingly urgent. The need for devices which would provide data is felt even more pressingly. If additional labor to read curves, instruments, and so forth, can be eliminated and the data obtained in numerical form, even further advantages can be obtained.
