Abstract
An instrument to measure leakage of steam which determines the operation status of a steam trap, e.g., if the steam is leaking or not, and measures the leakage rate of the steam and is devised to prevent rippling on the water surface at the primary side of a bulkhead in the instrument installed between the steam supply side and the steam trap so as to measure the quantity of steam leakage from the water level at the primary side of the bulkhead and the gas quantity passing through a passage formed in the bulkhead.
