Abstract

Provided is a flow computing apparatus which includes: a first computation task; a second computation task; and an access controller. The first computation task includes a flow rate computer configured to compute a flow rate of a fluid from sensor data indicating a state of the fluid, and a transaction information generator configured to generate transaction information indicating the flow rate ofthe fluid. The second computation task includes a management index computer configured to compute a management index related to supply of the fluid on the basis of at least a part of the sensor dataor index values computed during the course of the computation by the flow rate computer, and the access controller is configured to restrict at least a change in a function of the first computation task.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2017-197017 filed with the Japan Patent Office on October 10, 2017, and therefore the entire content of said Japanese Patent Application is incorporated herein by reference. technical field [0003] The invention relates to a flow calculation device. Background technique [0004] The flow calculation device for fluids such as liquids and gases is used for flow management and transactions of acquired fluids. The flow calculating device is, for example, an instrument for calculating the flow of fluid produced from production wells such as oil wells or gas wells. Flow computing devices for oil and gas are classified as "flow computers" and "distribution meters". The common point of any kind of flow calculation device is that it has the following functions: to perform thermal pressure correction on the sensor output (flow, pressure or temperature) installed in ...
