Abstract
The invention relates to an intelligent metering pry. An air inlet manifold is communicated with at least two air inlet branch tubes. Each air inlet branch tube is provided with a filter. Air is completely filtered by each filter and then goes into two metering branches. Each metering branch is provided with a flowmeter and an electric partition valve located behind the flowmeter. Two corresponding metering branches are combined into one air outlet branch tube. All the air outlet branch tubes are combined into one air outlet manifold. The intelligent metering pry further comprises an intelligent metering control box. The intelligent metering control box is in signal connection with the filters, the flowmeters and the electric partition valves. The flowmeters transmit flow data signals to the intelligent metering control box, and the intelligent metering control box chooses to open or close the electric partition valves on the metering branches according to the flow in actual operation, so that the appropriate measuring range of total flow is selected to achieve metering. Power lines are connected to an explosion-proof distribution box, and the explosion-proof distribution box supplies electricity to the intelligent metering control box and the electric partition valves. The intelligent metering pry is arranged in a gas company. Intelligent metering pries correspond to gas using units one to one.
