ABSTRACT:
A method and apparatus for eliminating trapped air from a liquid flow by using a buffer tank and an electrical control box such that substantially all the trapped air are accumulated in the buffer tank and further, when the tank is optionally equipped with a sensor system, the liquid flow can be shut-off when the liquid level in the buffer tank drops below a threshold level to prevent the trapped air from accidentally flowing into a process machine.
