Abstract
A gas safety device includes: a flow path; a flow rate measurement unit for measuring a flow rate of gas in the flow path; an absolute pressure sensor inside the flow path for measuring an absolute pressure of the gas; an absolute pressure sensor outside the flow path for measuring an absolute pressure of atmospheric pressure; a gas pressure determination unit for measuring a change in gas supply pressure from the absolute pressure of the gas and the absolute pressure of atmospheric pressure measured by the absolute pressure sensor and the absolute pressure sensor, respectively; a shutoff valve for shutting off the flow path; and a control circuit for: (i) controlling the flow rate measurement unit; and (ii) causing the shutoff valve to shut off the flow path when determining an abnormality from the flow rate of the gas or the change in gas supply pressure.
