In Canada’s energy sector—refining, petrochemical processing, terminals, blending, and emerging low-carbon fuels—small measurement errors in liquid handling can quickly become big operational problems. When fluids are corrosive, hot, pressurized, bubbling, or prone to coating, it becomes harder to trust a single instrument reading without a lot of compensation and maintenance.
On February 26, 2026, our partners at Vaisala are hosting a technical webinar focused on a practical question process and instrumentation teams face all the time: When is density the right measurement—and when is concentration measurement (based on refractive index) the better fit?

Westech Industrial Ltd. distributes Vaisala liquid measurement solutions in Eastern Canada, and we’re sharing this session because it’s especially relevant for anyone responsible for measurement reliability in challenging chemical service.
What the webinar covers
This webinar compares common density measurement technologies with concentration measurements based on refractive index, using examples from chemical-industry applications.
Topics include:
- How density is measured in industrial processes (and why it’s been used for composition measurement for so long)
- A look at typical density measurement technologies used in chemical applications, including:
- nuclear meters
- Coriolis (mass-flow effect) meters
- microwave methods
- ultrasonic methods
- Why many density approaches require compensations for real-world conditions such as temperature, pressure, vibration, coating, and other factors commonly present in demanding services
- Where refractometer-based concentration measurement can be advantageous—particularly in situations where process conditions introduce errors or delays for other methods
Vaisala notes that, in many chemical applications, refractometer-based concentration measurement can be a superior solution without certain errors associated with gas bubbles, changing pressure or velocity, or the time required for temperature equilibration.
Why this matters for Eastern Canada energy operations
Across Eastern Canadian facilities, “demanding chemical applications” show up everywhere—not only in chemical and petrochemical plants, but also in energy operations that handle solvents, amines, acids/caustics, glycols, brines, conditioning chemicals, and specialty fluids used for processing and treatment.
Choosing the right measurement principle can impact:
- Process stability and product quality (especially when concentration needs to stay within a tight operating window)
- Measurement confidence during upsets (startups, load changes, entrained gas, temperature swings)
- Maintenance workload and lifecycle cost (coating, fouling, recalibration frequency, troubleshooting)
- Environmental performance (reducing off-spec product, rework, and unnecessary venting or flaring tied to poor control)
If your team has ever debated whether a density meter is “good enough” in a harsh service—or whether a different approach could reduce compensations and headaches—this webinar is built for that conversation.
Who should attend
This session is a fit for:
- Instrumentation & controls teams
- Process and reliability engineers
- Operations leaders responsible for unit performance
- Anyone evaluating upgrades for difficult liquid measurement points
