This typical all-jacketed direct control Fluidometer System shows how the flow of liquid is controlled from supply tank to processing tank. In this installation the three units of the Fluidometer System (automatic reset ting control head, meter and control valve) are assem bled in one closely related grouping. These units may be placed remotely at some distance apart if plant arrange ment or convenience so suggest. T h e FLUIDOMETER '^/SHEO resets itself—automatically—eliminating the human ele ment, with its possibility of error, and insuring accuracy to within a small fraction of 1% in any type of service.
