Proven and reliable measurement

The determination of viscosity by reproducibility equal to or better than the capillary tube measurement is the most widely accepted industry standard.

Accuracy is crucial when determining a product’s resistance to flow, with even minor measurement errors potentially costing producers hundreds of thousands of dollars if a blend adjustment is made. By engineering our optimised measurement technology on a proven testing method, icon's Viscometer delivers an exceptionally accurate and trustworthy measurement.

Viscosity Index is also available.

How the Viscometer Analyser works

Viscosity is calculated by measuring the differential pressure across a capillary tube held at a constant temperature, a variable speed metering pump allows for multiple ranges using a fixed length capillary.

Precise temperature control is achieved by immersing the measuring capillary in a small stirred heated oil bath. Viscometer can accommodate a wide range of pressures and temperatures at the inlet and can return sample direct to the process.

The use of variable speed metering pump means the single capillary tube can be adapted for the wide range of viscosity measurements required by different products.


Optimised design

Extensive range of measuring temperatures and sample inlet and outlet conditions minimises the need for additional sample handling components, simplifying overall system design for a more reliable measurement.


Hazardous Area certified

Icon’s robust, explosion proof design is certified to the latest ATEX, IECEx and TIIS (Japan) standards and is suitable for zone 1 or zone 2 uses; and ETL listed for the USA and Canada Class 1 Div1 Group CD, depending on application.


Easy to use

Icon’s innovative touch screen user interface, auto validation and calibration options and extensive in-built diagnostics make operation simple. Digital control options include Wired Modbus RTU (RS485) and Modbus RTU over Ethernet (TC/IP) available as standard. OPC (wired) is also available.


Flexible Alarms

Alarm condition may be allocated as active or inactive, with alarms notified on screen and stored in an alarm history. Active alarms can be set to activate a warning alarm contact for notification, or a fatal alarm contact to suspend operation.
