Description
An Optical Air Eliminator for the M7 and M10 petrol meters. The Liquid Controls Optical Air Eliminator is designed for use with LectroCount® Electronic Registers. An optical sensor, installed in the wall of the air eliminator housing, is used to monitor the liquid level. The presence or absence of liquid at the sensor level activates or deactivates a solenoid valve located at the top of the air eliminator to vent air or vapor from the system. The optical air eliminator is designed to work with Liquid Controls M5, M7, M10, M15, and M25 meters, for applications measuring refined petroleum products. Designed with the same mounting dimensions as Liquid Controls mechanical air eliminators, the optical air eliminator does not require plumbing changes to retrofit to existing meter installations; however, electronic registers do require CPU board part number 81920 for LCR and LCR-II; CPU board part number 81924 for LC³. The optical air eliminator also requires the use of a solenoid-operated control valve such as the E-7 or A2848-11 on the outlet side of the meter.
