FLOW COMPENSATION OF FLOW MEASURER AND MANAGEMENT DEVICE THEREOF

摘要

PURPOSE: A flow compensation of a flow measurer and the management device are provided to increase safety, decrease a gas interception caused by a mis-judgment and easily change a set value. CONSTITUTION: The flow compensation of the flow measurer and the management device comprise:a temperature compensation coefficient judging unit(4) compensating real passing gas amount and proper using amount according to an outside temperature and/or pressure in a gas meter; a pressure compensation coefficient judging unit(5); a flow amount compensating unit(6) compensating flow amount about temperature and pressure; a consumptive state memory unit(7); an error interception signal unit(14) for preventing gas intercepting by mis-operating; a proper gas using amount expectation unit(11); and an intercepting unit(13) intercepting gas if the gas using state is abnormal.
