The ability to accurately measure and control critical process parameters is vital for achieving consistent performance, minimising waste, and maximising productivity. By providing real-time data, inline measurements from various sensors can enable you to gain valuable insights into process behaviour, facilitating informed decision-making and process optimisation.
Viscosity measurement in particular is of paramount importance for many industries and applications, but there are lots of different technologies available. This means there's a lot to think about when it comes to choosing the right viscometer. The right instrument should be optimised for use in the process and deliver a reliable, repeatable signal you can trust, whilst providing many years of trouble-free operation. All with minimal maintenance and downtime.
Below we've compiled a list of the key features to look for in a process viscometer:
1. Performance
Look for a viscometer that offers high measurement accuracy and reproducibility to ensure precise and reliable viscosity readings. Consider the viscometer's repeatability, resolution, and sensitivity to variations in viscosity and make sure this aligns with your requirements.
2. Viscosity Range
Evaluate the viscometer's capability to measure viscosity across a wide range, even down to zero. Often this can reveal a lot about the stability of the measurement. Consider whether the instrument can handle both low and high viscosity fluids to meet your specific application needs.
3. Installation and Maintenance
Assess the ease of installation and ongoing maintenance requirements. Look for a viscometer that can be easily integrated into your existing system or process. Consider factors such as sensor size, mounting options, and accessibility for cleaning and maintenance.
4. Temperature and Pressure Sensitivity
Evaluate the viscometer's ability to provide accurate measurements under varying temperature and pressure conditions. Nothing effects viscosity more than temperature, so it's essential to choose a viscometer that can track this relationship reliably.
5. Reliability and Durability
Is the instrument reliable and durable? Consider factors such as the construction, quality of materials, and the manufacturer's reputation for producing robust and long-lasting instruments.
6. Calibration and Validation
Take a look at the calibration and validation processes of the manufacturer. Look for instruments that offer easy and traceable calibration methods, as well as validation procedures that ensure accurate and reliable measurements.
7. Cost of ownership
Consider the overall cost and lifetime value of the viscometer. A lower entry price may not always mean lower cost of ownership. Compare the features, capabilities, and performance of different models against their price and also consider factors such as maintenance and costs of process downtime if instruments need to be taken offline. Look for a balance between long term value and meeting your specific viscosity measurement requirements.
