ABSTRACT:
Liquid sampling apparatus for sampling liquid at a controlled depth within the tanks of an ocean going oil tanker comprises a sampling chamber having outwardly opening inlet and outlet valves. The inlet valve 114 is arranged to be actuated by a projecting valve actuator 132 through a lever mechanism and is adjustable by means of a spring clip 136 so as to permit sampling at varying distances from the bottom of the tank. The outlet valve is a pressure-relieving ball valve 138 permitting automatic escape of air during filling of the sampling chamber, but preventing entry of liquid. The apparatus is lowered in use through an MMC stand on a wire carried by a support 140 at the top of the apparatus.
