KOBOLD's DON Oval Gear Positive Displacement Flow Meters are the ideal solution for measuring clean high and low viscosity liquids such as lubricating/hydraulic oils, petroleum, ink, diesel fuels, grease, chemicals, solvents, resins, pastes, and molasses. Due to the mechanical nature of the operating principle, media with particulate matter is not recommended for use with the DON.
The heavy-duty industrial oval gear design design employs two precision-machined gears that are turned by the force of the flowing media and they allow a very specific known volume of liquid to pass through the meter with each rotation. These gears enable the DON to precisely measure liquid flow over a very wide viscosity range and provide a high accuracy volumetric flow rate measurement.

Because the measurement principle provides a true volumetric flow measurement, the DON is also ideal for flow rates that fluctuate widely and for flow that is intermittent. High accuracy measurement is assured even though these are process variables that would render other flow meter technology types non-compatible.
To accomodate even higher process pressure than our standard DON Oval Gear Flow Meter, KOBOLD also makes the DON-H High Pressure Oval Gear Flow Meter. It offers the exact same rugged and reliable service for high viscosity liquid measurement.
KOBOLD offers a comprehensive line of Positive Displacement Flow Meters including other Oval Gear Flow Meters, Rotary Piston Flow Meters, and Helical Screw Gear Flow Meters.

We are the industrial instrumentation partner of choice with comprehensive solutions for measuring what matters to you.
For over 40 years, KOBOLD has been a value-driven leader in process measurement and control solutions. We offer one of the industry’s broadest lines of sensors, switches, and transmitters to measure and control flow, pressure, level, and temperature.
We offer excellence in engineering, high value products, and exceptional customer partnerships that last beyond the sale. Because we design, manufacture, sell, and provide support for our products, you can be assured that you and your application are in expert hands.
We aren’t just interested in selling you instrumentation. You are our priority. Trying to wade through the extensive technologies and options can be a bit intimidating. You don’t have to figure it out on your own. We are here to partner with you, providing free advice from our in-house engineering experts who have decades of collective experience.
We are old-fashion in our beliefs about what doing business should look like. We still have someone answering our phone who will quickly direct you to the right person. We still believe in delivering true value and not subpar quick-fix products that become headaches down the road. We build our products like we build our relationships, for the "long haul".
For certain large-scale projects, we are also able to provide demo instrumentation so you can be confident that our solution is the right fit for your application. We want our products to be the best fit as much as you do. There is no project too large or too small for us.
We believe that "Made in the USA" still means something. Our products are built with that in mind as we aim to exceed the standards and ideals of quality-focused US manufacturing. We offer the best of both worlds. German engineering is still known as being among the finest and we are proud to build some of the most innovative products in the world. We are also focused on sourcing practices that allow us to provide higher quality components, shorter lead times, and longer lasting products than other instrumentation manufacturers.
We offer one of the industry’s broadest lines of sensors, switches, and transmitters to measure and control flow, pressure, level, and temperature.
We have historically set the bar for innovation and excellence, helping to shape the field of industrial instrumentation into what it is today. Our technologies offer a solution-oriented way to control the most diverse and complex variables and can be easily integrated into a wide variety of systems in many industrial and commerical sectors.
We will not try to sell you any instrumentation that isn’t ideally suited for your application. Because we are unique in the extensiveness of our product line, we don’t have to try and “force a fit” just to make a sale like other companies with limited product lines. In the event we do not have the right solution, we will do our best to point you in the right direction.
While we offer a wide variety of standard instrumentation, we are also able to handle unique, difficult, or challenging applications that others can not. Our familiarity with exotic materials allows us to offer solutions for variables that are frequently hard to accommodate. Because we are the manufacturer, we also have the flexibility of being able to provide customized solutions in certain circumstances, based on the exact application needs.
