Abstract
Apparatus indicating the quantity of fluid in a closed and pressurized fluid circulating system. The apparatus compensates or corrects for fluid expansion and contraction due to temperature change so that the indicated quantity is the true quantity. The apparatus includes a direct acting, mechanical connection from a fluid accumulator-reservoir device to an indicator. A thermostat sensing fluid temperature introduces a correction into the mechanical connection.
