Abstract:
A gas estimation device for estimating a flow rate and a gas type of gas to be vacuum-pumped by a vacuum pumping device including a vacuum pump and an automatic pressure control valve connected to a suction port of the vacuum pump, comprises: a correlation data storage section configured to store first correlation data containing correlation data regarding an opening degree control gain value of the automatic pressure control valve and correlation data regarding an effective exhaust velocity of the vacuum pumping device and second correlation data indicating a correlation among a flow rate, a gas type, and a motor current value in the vacuum pump; and a first estimation section configured to estimate the flow rate and the gas type of the gas to be vacuum-pumped by the vacuum pumping device based on at least the first correlation data and the second correlation data.

Claim (Index 4):
The gas estimation device according to  claim 3 , further comprising:\n a determination section configured to determine, based on the flow rate estimated by the second estimation section, whether or not a flow rate upon pressure measurement for each of the multiple valve opening degrees is the predetermined flow rate.
