Accessories air / vapor eliminators and strainers Liquid Controls provides a variety of precision-engineered accessories including strainers, air and vapor eliminators, and valves designed to ensure that your measuring system performs accurately and trouble-free from startup and through the long service life of the equipment. Costly measuring inaccuracies or maintenance problems can result whenever air, vapor, rust, scale, or other foreign materials are introduced into the flow of liquid. Air /vapor eliminators Air and vapor eliminators are installed on the inlet side of the meter in order to maintain high-accuracy liquid measurement. The combination of an air eliminator with a downstream differential valve or air check valve minimizes the passage of air or vapor through the meter. The mechanical LC air eliminator consists of a housing that contains a float assembly in combination with flexible reed strips and two orifice plates to control elimination of free air or vapor. Air/vapor elimination is required for Weights and Measures regulatory approvals in custody transfer applications. The optical air eliminator developed by Liquid Controls is available for use with M-5, M-7, M-10, M-15, and M-25 meters for refined petroleum products. This system features optical sensing for liquid level detection and no moving parts for optimal field performance.
