In a temporally continued plurality of day-and-time sections, history data included in the past day-and-time section is graphically displayed on the basis of the integrated flow amount data stored in the storage unit, as an integrated flow amount in each day-and-time section. In the day-and-time section including the current day-and-time, the integrated flow amount in the day-and-time section based on the current integrated flow amount data is successively updated and graphically displayed.

Gas flow meter for graphically displaying and indicating a history of integrated flow amount

To provide an apparatus for monitoring a fluid flow rate, which is capable of performing monitoring without a data deficit, and displays information on a trend of a past history. A monitoring apparatus accepts, from the flow meter, integrated flow amount data for every day-and-time section, and a current flow rate, and graphically displays, on the basis of the integrated flow amount data for every day-and-time section, an integrated flow amount corresponding to each day-and-time section, on the basis of the integrated flow amount data for every day-and-time section including the current day-and-time and for every another plurality of continuous day-and-time sections.

Monitoring apparatus for graphically displaying and indicating a history of integrated flow amount of gas flow meter

To provide a sensor unit that simultaneously displays other information together with a threshold and a physical quantity. A sensor unit causes a dot-matrix display unit to display a threshold and a physical quantity in a first display form and causes the dot-matrix display unit to display, together with the physical quantity and the threshold, additional information (e.g., a power mode) different from the physical quantity and different from the threshold in a second display form. The area of a third display regionfor the threshold in the second display form is smaller than the area of a second display regionfor the threshold in the first display form. The area of a fourth display regionfor the information in the second display form is obtained by reducing the area of the second display region
