The Liquid Controls Optical Air Eliminator is a device used primarily in liquid dispensing systems to remove air from the liquid flow. Its main purpose is to ensure accurate and consistent measurement during the transfer of liquids, especially in applications where precise volume control is crucial, such as in fuel dispensing or chemical processes.

The device works by utilizing optical technology to detect and remove air pockets in the liquid flow, which can cause inaccuracies in the measurement or affect the performance of the system. This is especially important in applications where even small air pockets can lead to incorrect readings or disrupt the operation.
