Optical Air Eliminator

Patent Applied For

The Liquid Controls Optical Air Eliminator is designed foruse with LectroCount
® Electronic Registers. It providesfor the efficient elimination of air and vapor with virtuallyno moving parts and without the need for floats, guide rods, reed strips, and valve plates. An optical sensor, installed in the wall of the air eliminator, is used to monitor the liquid level. The presence or absence of liquid at the sensor level activates or deactivates asolenoid located at the top of the air eliminator. TheOptical Air Eliminator requires the use of a solenoid operated valve such as the E-7 or A2848-11 supplied by Liquid Controls.The solenoid operated, air-release valve, located at thetop of the air eliminator, is either open or closed. Whenthe liquid level is below the optical sensor, the solenoid opens and vents air and vapor to atmospheric pressure. Simultaneously, the electronic control valve (E-7 or A2848-11) at the meter outlet closes.When liquid rises to the optical sensor level, the solenoid closes and prevents continued venting toatmospheric pressure, and the electronic control valve at the meter outlet opens so that a delivery maycontinue. This functionality ensures that only liquid passes through the meter for measurement andfacilitates passing Weights & Measures split compartment testing.The optical air eliminator is designed to work with Liquid Controls M5, M7, M10, M15, and M25 meters, forapplications 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 toretrofit to existing meter installations with electronic registration. Electronic registers require CPU boardpart number 81920 for the LectroCount LCR and LCR-II and part number 81924 for LC³.
