Compressed gas flow measurement and display device has a display base made using electronic paper that is controlled by a data acquisition and control device dependent on the measured flow or pressure

摘要

Measurement and display device, especially for measuring the flow and pressure of a compressed air supply. The device has a display (8) with display means (12) made from electronic paper, a data capture and control arrangement that creates the display output dependent on the flow properties and a solar cell power source (14).
