Abstract: An object is to enhance usability when browsing through a measurement result from a sensor on an external computer. A data relay device includes a first connection part to which one or more sensors are connected, a second connection part to which an industrial network for communication with a control device is connected, a relay memory that temporarily stores first data received from the one or more sensors connected to the first connection part to relay the first data to the control device via the second connection part, a third connection part to which a computer network for communication with an external computer is connected, a creation unit that creates display screen information for use in displaying the first data stored in the relay memory in a predetermined display form, and a provision unit that provides the display screen information to the external computer via the third connection part.

Abstract: To provide a flow meter capable of easily acquiring, with a simple configuration, an integrated value of a flow rate in every flow of fluid intermittently flowing in a pipe. A flow-rate measuring section 302 measures a flow rate of fluid flowing in a pipe. A value of the flow rate integrated from a point in time when the integration of the flow rate is started to a point in time when the integration of the flow rate is stopped is acquired as an integrated value. A reset section 306 resets the integrated value from a point in time when the integrated value is acquired to a point in time when the next first switching is determined.
