Abstract
A liquid level monitor () includes a liquid bowl cavity () having a liquid sampling port (). A switching device cavity () is formed within an upper portion of the housing () having an electromechanical switching device () therein. A separator () is between the liquid bowl cavity () and the switching device cavity (). A venting pathway () including a vent passage () is for equalizing pressure between a region over the liquid in the liquid bowl cavity () and the switching device cavity (). A liquid level indicator including a float () is positioned in the liquid bowl cavity () for indicating the height of the liquid. The liquid level indicator () actuates the electromechanical switching device () when the fluid level falls below a predetermined level. A mechanical barrier () is positioned in the venting pathway () for redirecting liquid back into the liquid bowl cavity ().
