Title: System for metering liquid

Abstract: A measuring cylinder into which liquid is supplied is provided with pressure transmitters for sensing the liquid pressure corresponding to the amount thereof. The pressure transmitters are connected with a pressure transformer to transform the pressure into an electric signal for controlling valves to stop and start the supply of liquid into the cylinder. The pressure transmitters are located in the cylinder at different levels and switched to be selectively operated in combination with the pressure transformer. In a preferred embodiment of the invention, the shape of the cylinder is designed so that the diameter thereof increases discretely from the lower part to the upper part thereof. One of the pressure transmitters is located at the bottom of the cylinder and the others are located at levels substantially the same as those at which the diameter of the cylinder increases.
