OG Oval Gear Flowmeters

Maximum/minimum flow rates are dependent on viscosity - for more information contact our sales office. The chart above is for standard configurations; alternative end fittings and body sizes are available, we can even match your installation requirements i.e. manifold fittings or sizes to replace a redundant flow meter generated.
