ABSTRACT:
A metering system is provided for automatically controlling and monitoring corrosive liquids. The system includes a pneumatically or electrically actuated valve and a meter upstream of the valve. The meter includes a device for transmitting an electrical signal proportional to the flow through the meter to a controller means which receives the signal and counts the volume units of flow. The controller also includes a device to transmit an electrical signal to stop the flow of corrosive liquids at a predetermined volume level. The system includes a timer for activating the system at a preset time and a valve actuator means. A method for automatically controlling and monitoring the flow of corrosive liquids is also provided.
