Abstract
The present invention provides a gas leakage sensing device comprising a gas conduit, a liquid storage tank and a bubble sensing component. The gas conduit guides leaking gas from industrial equipment into a liquid in the liquid storage tank through an exhaust port and generates bubbles. A monitoring part with a bubble sensing component is formed on the tank wall of the liquid storage tank, the height of the monitoring part from the liquid surface is less than the height of the exhaust port from the liquid surface. By sensing the size, amount of generated bubbles, and floating frequency of the bubbles generated in the liquid, the flow rate and volume of the leaking gas are obtained to improve the accuracy of sensing the leaking gas.
