NEW DON-H: Oval Gear Flowmeters for High Pressures

High Performance at Higher Pressures

With stainless steel bodies and rotors, the economical DON-H is built to handle high pressures up to 5800 PSIG, while delivering high performance. It is engineered to precisely measure clean, non-abrasive liquids with viscosities up to 1000 centipoise and temperatures up to 250° Fahrenheit. Even higher viscosities, up to 1,000,000 centipoise are available with special cut rotors. Common application media includes: petroleum, oil, chemicals, grease, fuels, ink, pastes, etc. Measuring ranges are available in 0.13 to 9.5 gallons per minute up to 0.26 to 10.6 gallons per minute. Connections are offered from 1/8” to 1/2” NPT.

How it Works

Oval gear flowmeters, like the DON-H, are a type of positive displacement flow technology. The flowing media engages two oval geared rotors, which measure a constant volume per rotation. This rotation is sensed via magnets, embedded within the rotors, which transmit a high resolution pulse output. The resulting signal can be processed via a remote display controller, a PLC, or via other options like batchers and totalizers. Flow profile conditioning is not required making it simple to install in tight spaces. Liquid properties, such as conductivity, have a minimal effect on the DON-H.

Part of the DON Series

For applications with lower pressure requirements, consider our standard DON, available in stainless steel or aluminum bodies. The DON also offers: higher measuring ranges, bigger lines sizes, flanged connections, and bi-directional flow sensing with an optional quadrature output.
