The Kobold DON-H series oval gear flow meter offers reliable flow rate measurement for demanding process conditions. The DON-H is suitable for clean, high and low viscosity liquids such as lubricating/hydraulic oils, petroleum, grease, diesel fuels, chemicals, solvents, resins and pastes and uses two precision-machined oval gears which allow a very specific volume of liquid to pass through the meter with each rotation, providing a true volumetric flow measurement. These gears enable the DON-H to precisely measure liquid flow over a very wide viscosity range, accomodate fluctuating flow rates, a provide accuracy for applications with intermittent flow. Because of the mechanical nature of the measurement principle, media with particulate matter is not suitable for use with the DON-H.
