摘要： Techniques for converting a diaphragm gas meter into a static gas meter-that uses some of the enclosure of the diaphragm gas meter-are described. In an example, a lower portion of the enclosure of the diaphragm gas meter is separated from an upper portion of the enclosure of the diaphragm gas meter. The lower portion of the enclosure contains the diaphragm, and may be discarded appropriately. The upper portion of the enclosure may be of a type having a monopipe connector. The monopipe connector may include an inlet and an outlet. A static gas metrology assembly can be connected to an upstream end of a monopipe adapter. A downstream end of the monopipe adapter may be connected to the outlet of the monopipe connector of the upper portion of the enclosure. A cover or base-plate may be attached to a flange of the upper portion of the enclosure.

摘要： Gas meter (10) includes shutoff valve (1), return unit (2), flow rate measurer (3), display (6), communication unit (4) that communicates with an outside, controller (5), area information setting unit (7), and area information comparator (8). The gas meter compares, by area information comparator (8), a preset area information held in area information setting unit (7) with a specified value of area information added to a remote shutoff instruction received by communication unit (4), and when the preset area information and the specified value of the added area information match, shutoff valve (1) is closed.

摘要： A gas meter includes meter body (103) having meter inlet (101) into which a fluid-to-be-measured flows and meter outlet (102) from which the fluid-to-be-measured flows out, and extended section (101a) extended from meter outlet (101) to the interior of meter body (103). The gas meter further includes flow rate measurement unit (10) disposed inside meter body (103), flow rate measurement unit (10) having measurement flow passage (12) having a straight tubular shape and provided with lead-in port (12a) and lead-out port (12b) for the fluid-to-be-measured, and shutoff valve (14) disposed in internal passage (101b) of extended section (101a). In flow rate measurement unit (10), lead-in port (12a) is airtightly connected to extended section (101a) to communicate with internal passage (101b).

摘要： A gas meter includes a meter entrance (22) that allows a fluid to flow in, a meter exit (23) that allows the fluid to flow out, and a flow rate measurer (24) that measures a flow rate of the fluid. In addition, the flow rate measurer (24) includes a plurality of flow rate measuring units (26 and 26) of a same shape composed of a flow passage portion having a rectangular cross section shape on the outer side and a sensor portion (30) disposed on one face of the flow passage portion. The plurality of flow rate measuring units (26 and 26) are integrally configured by bonding faces having no sensor portion as bonding faces of the flow rate measuring units.

摘要： Flow rate measurement device (100) includes flow rate measurement unit (104) that measures a flow rate of gas at a prescribed time interval, and arithmetic unit (108) that calculates a characteristic flow rate from the flow rates measured within a predetermined period, and calculates a ratio of each flow rate measured at multiple times within the predetermined period with respect to the characteristic flow rate. In addition, flow rate measurement device (100) includes appliance characteristic extraction unit (116) that extracts an appliance characteristic quantity which indicates a characteristic of a flow rate change in currently using gas appliances (13, 14, and 15) within the predetermined period, the appliabce characteristic quantity being the ratio or information obtained from the ratio, and appliance inherent characteristic information holding unit (119) that holds an appliance inherent characteristic quantity indicating a characteristic flow rate state of a specific gas appliance. Furthermore, flow rate measurement device (100) includes appliance discrimination unit (114) that discriminates the currently using gas appliance by comparing the appliance characteristic quantity with the appliance inherent characteristic quantity.
