PURPOSE:To automatically, accurately and swiftly sample a liquid by providing an electronic circuit mechanism which controls the operation of sampling liquid and the number of times for sampling liquid the amount of which is set by the distance between the top levels of each two glass rods inserted into each measuring tank. CONSTITUTION:Each two of glass rods 4, 5, 9, 10 are inserted into each measuring tank 1, 6, and a specified amounts of liquids which are set by the distances between the top end levels of each two glass rod are sampled from a storage tank 13 into a vessel 12 by the opening and shutting operation of four solenoid valves 2, 3, 7, 8 controlled by the electronic circuit 11. At the same time, each number of times of the influent liquid from the storage tank 13 and effluent liquid from each measuring tank 1, 6 are controllable by the electronic circuit 11. Moreover, when another storage tank is installed and two kinds of liquids are stored in the two storage tanks, various specified rate of mixture or dilution of two liquids can be carried out. |
