Welcome to the Home of Process Viscosity from Hydramotion
The biggest range of viscometers for any fluid in any application anywhere!
A Hydramotion viscometer has no moving parts, seals or bearings that can wear out or fail in service.
The XL7 on-line viscometer is a "bolt-on-and-go" device that can be installed directly onto any process line. The RV-100 viscometer provides real-time viscosity monitoring in the laboratory or the pilot plant, and the Viscolite Portable Viscometer is ideal for the spot measurements of viscosity anywhere, in the field, factory or lab.
Making Waves in Sensor Technology The XL7 viscometer is in a class of instruments called vibrational or resonant viscometers. Vibrational viscometers work by creating waves - but it turns out that the type of wave is very important. Not just any wave will do. Viscosity is a shear measurement. It can only be truly assessed under shear conditions, so we use shear waves. There are many other types of vibrational waves, but these are avoided as they can behave unpredictably in process environments. To the naked eye, nothing moves. The solid stainless steel sensor element is submerged in the fluid and made to move back and forth microscopically at a high frequency. This is called "resonance". As the surface of the sensor shears through the liquid, energy is lost to the fluid because of its viscosity. The dissipated energy is accurately measured by microprocessor-controlled electronics and then equated back to viscosity. Higher viscosity causes a greater loss of energy and hence a higher reading. The harnessing of the wave dissipation principle with solid engineering design gives Hydramotion viscometers a rare combination of incredible sensitivity and toughness. Intrinsically Safe Viscometers Every type of XL7 transducer is available as an intrinsically Safe (IS) version to EEx "ia" IIC T6 suitable for Div1 Class 1 Group A in North America and carries certificates for the following international standards:
IS certification permits a simpler installation than flameproof. The EEx "ia" certificate allows transducers to be operated even in the most hazardous Zone 0 environments. Full details of certifications are available upon request. |

Hygienic Design |
 |
The viscosity measurement technique employed in the XL7 viscometer is ideally suited to industries where contamination must be avoided. The viscometer has a truly hygienic design with an all-welded 316SS construction, no seals, bearings or moving parts, and it is clean-in-place (CIP) compatible. All transducers can be supplied with any size or type of sanitary fitting, including quick-release tri-clamp mountings, RJT, IDF, DIN and others.

Viscometer Applications |
||||||||||
 |
If it's a fluid, we can measure it --- and usually with a standard off-the-shelf instrument. Where there are unusual requirements, a standard XL7 process viscometer can often be modified to suit. And if you have a really special application, a bespoke viscometer can be manufactured to meet your particular needs. So whether it's resins or chocolate, polymers or inks, tanks or pipes, hot or cold --- if you want viscosity measurement with on-line accuracy and sensitivity that can exceed that of the lab, maintenance-free and long duty without recalibration, there is an XL7 viscometer that will do the job. |
