Natural gas measuring and billing system

摘要

The natural gas metering system comprising at least two different throughput measuring circuits with gas meters and valves installed on them shall be characterised by this, that a valve (3) equipped with a control (5) connected to a gas meter (7) with a low flow measurement flow rate of flowing gas is installed on the first measurement line (1), and on the second measuring line (2), a valve (4) is fitted with a controller (6) connected to a gas meter (8) with a high flow rate measurement of the flow rate of the gas flowing, and the controllers (5, 6) installed on valves (3, 4) are connected to the controller (9),in the form of a microcontroller switching the measuring circuits (1, 2),to which a signal conditioning system (10) replacing pulses in rectangular form is connected and also gas meters (7, 8) located on individual measuring lines (1, 2) are connected;which transmit impulse signals to the controller (9).
