XL7.  In Line.  In Control

Hydramotion is the name industry turns to for in-line product viscosity.
There are other viscometer manufacturers. But no-one else makes the XL7.

The Finest Details

A fusion of robustness and high precision that can track the tiniest changes in viscosity, the XL7 sets the standard for in-line measurement. That’s why companies demanding the highest performance and reliability insist on Hydramotion.

We want the sensor to pick up every detail of the fluid viscosity. So it sits in the centre of the flow. There are no shrouds or guards in the way so the slightest change in the fluid is sensed instantly.

Peace of Mind

XL7 viscometers have become the trusted reference in the process. Around the world they work day and night providing vital fluid measurements for businesses that depend on getting viscosity right.

Peace of mind comes from the investment we put into the design and manufacture of our products. We know where they are used and what is expected from us.

The build quality is peerless. And our Validation Lab ensures that every instrument leaving our Production Centre has the same performance our customers demand.

Increase Quality
Eliminate Waste

Measuring and controlling viscosity in real time with the XL7 can transform your manufacturing.

The very high sensitivity of the XL7 makes it able to detect the tiniest changes in fluid viscosity, even in stressful conditions. Abnormalities in the process can then be picked up instantly or even predicted.

Action can then be taken, either manually or automatically, to keep the product within specification. This delivers consistent quality whilst driving down waste.

And that means less cost of manufacture and more customer satisfaction.

Nothing Troubles the viscometer

Surface Loaded

The XL7 is ‘surface loaded’. All the action takes place right on the sensor. This means it’s not troubled by pipe or tank sizes, flow, or any of the things that affect other techniques.

So you can use it anywhere. The most noisy, hot, cold, fast, hygienic, aggressive, hazardous, or extreme environment you can imagine. In fact, any fluid that needs to be kept at its optimum.

Calibration is unaffected by location. Whether its a teacup of fluid or a tankful, you’ll get the same viscosity reading.

This means you can use the XL7 freely, with no loss of performance. It also means it can be redeployed elsewhere if things change. A versatile and future-proofed asset.

XL7 process viscometer with various connections

Any Fluid.
Any Application.

With a wide range of process fittings, materials and
finishes there is an XL7 for every application. It is designed to fit directly onto your existing plant with no alterations to pipework.

Installation is simple. Just fit to the line, connect power and you’re ready to go.

There are no moving parts to replace or service, along with the unwelcome downtime. Instead, there is negligible maintenance and an unbeatably low cost of ownership. So all the attention is on your product, not ours.

All shapes & sizes

We do not live in a standard world. We routinely produce viscosity meters to meet unusual or special requirements and have a dedicated division for this purpose – Special Ops. They find cost-effective solutions to specific client needs. These include everything from (very) long reach sensors to diminutive viscometers for small pipes and vessels.

Instruments can also be supplied in a range of alternative materials and finishes. The choice is yours.
