Gas seal column apparatus with sensor column

Abstract

A gas seal column apparatus includes a pump drive motor, a gas seal column, a pump system, a level sensor, and a control box. The gas seal column receives a seal gas for pressurizing the gas seal column. The pump system includes a pump and the gas seal column. The pump system is coupled to the pump drive motor and moves a product through the pump. The level sensor is supported on a sensor column that is separate from the gas seal column to detect a level of the product in the gas seal column and any fumes in the gas seal column. The control box is in communication with the level sensor and controls the seal gas received within the gas seal column and the sensor column to control an amount of fumes and the level of the product within the gas seal column.
