Product Description

The DOE Series oval gear positive-displacement flowmeters are the OEM's preferred choice for measuring viscous, non-abrasive, clean liquids such as lubricating and hydraulic oils, diesel fuels, chemicals, solvents and resins. This compact flowmeter uses 2 precision-machined oval gears which allow for a specific volume of liquid to pass through the meter with each rotation. These gears enable the DOE flowmeters to precisely measure liquid flow over a very wide viscosity range. As this is designed to be an OEM product, minimum order quantities will apply.
