Compact, Low Cost Inline Vortex Flow Meters

KOBOLD DVZ inline vortex flow meters for low viscosity liquids feature a long service life and low maintenenace as they do not utilize a mechanical means of measurement, where components can break or wear out, and are the perfect solution for applications requiring reliability and low cost.

The DUK is available with a PPS body and your choice of either nickel-plated brass or 316 stainless steel fittings. The bluff body is available in either the standard PPS or optional ceramic material, which has excellent long-term wear characteristics even under harsh operating conditions. Available outputs for the DVZ include pulse frequency, 4-20 mA, adjustable relay, and compact electronics with LED digital flow rate display, 4-20 mA output and adjustable transistor switch options.

Vortex Measurement Principle

The DVZ senses flow rate using the vortex-shedding principle. A small obstruction, known as a bluff body or shedder-bar, is placed within the flow path. As flow occurs past the bluff body, small low-pressure vortices (swirls) are created just behind it. The vortices alternate to either side of the bluff body in a uniform pattern and the frequency of the vortex shift is directly proportional to flow rate. A very sensitive pressure sensor is used to detect the shifts and a scaled flow rate signal is produced.

Other Vortex Flow Meter Types

KOBOLD also offers the DVE Insertion Vortex Flow Meter which is also a multivariable vortex flow meter. The DVH Vortex Flow Meter is an inline multivariable flow meter for more demanding process elements.

Who Are We?

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.

Why Choose KOBOLD?

Our Approach: Partnership for the "Long Haul"

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.

US Manufacturing Built on German Engineering

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.

Comprehensive Product Line: We Don't Have to "Force a Fit"

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.

Unique/Difficult Applications & Customizations: We Do What They Can't

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.
