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.

Application Notes

Here's how some of our customers used this product.

High Viscosity Fluid Test Lab Meter

The Background: Our customer is a large food company that seeks a flow meter for use in their product development test lab.

The Problem: The test lab will need to measure the flow of food products, some of which have a very high viscosity (in excess of 10,000 centipoise) over a range of pressures and temperatures.

The Solution: We recommended the Kobold DON Series Oval Gear Flow Meter. The design of gear meters allows for very accurate and repeatable flow measurements over a very wide viscosity range and in varying process conditions.
