<p>[QUOTE=&quot;Joe in PA, post: 9490906, member: 12740&quot;]Foxborough makes pressure and flow measuring systems. This looks like part of one of those. It could have measured the height of a column of water or mercury or something to measure pressure or flow rate.&nbsp; Flow is often measured by using pressure drop across an orifice or other element so that could explain the nonlinear nature of the scale. You can probably find it in one of their catalogs if you dig around.[/QUOTE]</p><p><br /></p>
