The Kobold DON Series Oval Gear Flow Meters measure clean, high and low viscosity liquids such as lubricating/hydraulic oils, diesel fuels, chemicals, solvents, resins and pastes. This flowmeter uses two precision-machined oval gears which allow for a very specific volume of liquid to pass through the meter with each rotation. These gears enable the DON flow meters to precisely measure liquid flow over a very wide viscosity range.
The Oval Gear meters are positive displacement flowmeters where the flow of liquid causes two oval gears to rotate within a precise measuring chamber and with each rotation a fixed volume of liquid passes through the meter. Magnets embedded within the gears are sensed to create a high resolution pulse train output. The pulse output can be wired directly to process control and monitoring equipment or can be used as an input to a conditioning electronic or display supplied with or attached directly onto the meter.
