With stainless steel construction, the XL/7 in-line process viscometer from Hydramotion is designed for in-line measurement and control of printing ink viscosity. Hydramotion said that patented technology means that the sensor rejects plant noise and vibration and is unaffected by fluctuations in flow, or the presence of bubbles or particulate solids.

The XL/7 has no moving parts, is said to no require on-site calibration, and intrinsically safe models are fully Atex and Cenelec certified. The sensor is installed directly into the fluid flow and long-reach sensors are available for applications where the fluid is inaccessible, such as tanks or large- bore pipes.

Viscosity is measured every 3 s and displayed on the separate signal processor, which can be up to 3,000 m from the transducer. Compensation software enables viscosity measurements to be corrected to a reference temperature.

The instrument is claimed to be accurate to within ± 1 per cent of the reading and has high resolution even at very low viscosities.

Every viscometer is factory calibrated to traceable international standards. Maintenance requirements are said to be minimal as there are no seals or bearings.

All models can be supplied with highly polished or PTFE-coated sensors to minimise cleaning.
