12. por Eliminators What LC Air and Vapor Eliminators Do The Liquid Control s vapor and air eliminators are de signed to remove free air or vapor from the system before the air or vapor enters the measuring chamber The com bination of the vapor eliminator with the differential valve or with the air check valve assures that only liquid will flow through the metering system thereby providing the most accurate liquid measurement The LC Air and Vapor Eliminators consist of a housing that contains a float assembly The float assembly in combination with flexible reed strips and two orifice plates How LC Air and Vapor Eliminators Work The Housing The housing is comprised of a chamber that is open at the base for product to enter It has one small rectangu lar opening centered on each of two of the opposing sides Covering each rectangular opening is a valve plate The valve plate has a vent port in the center section of the plate The vent port is either an oval or circular hole The valve plate is sandwiched between the housing and the cover plate The cover plate has a circular hole for connection to an external pipe for venting The Float Assembly Inside the housing is the float assembly The float as sembly is made up of a float that has a stem assembly attached to its top Attached to each of the two sides of the stem assembly is one stainless steel reed strip Each reed strip is attached to the outside of the housing at the ba
