Coriolis Flow Meter for High-Viscosity Fluids

High-viscosity service changes pressure loss, start-up behavior, and the usable flow range. A properly sized Coriolis meter can still provide direct mass-flow measurement for oils, resins, adhesives, coatings, polymers, and syrups.

Confirm viscosity across the operating range

Do not size from a single room-temperature viscosity. Record the minimum and maximum process temperature, expected viscosity at start-up, and whether the fluid contains suspended solids or entrained air. Heating or trace-heating the line may be necessary to keep the fluid pumpable and the meter within its specified range.

Control pressure loss

Choose a meter size that meets the required flow without creating an avoidable restriction. A larger line connection does not automatically improve accuracy; the meter must maintain a stable, full tube and a measurable flow. Check the manufacturer's pressure-drop data at the actual viscosity, not only with water.

Installation practices

Use a rigid support, eliminate bypass leaks, and locate the meter where it remains full during shutdown. For products that can settle or cure, plan drainability and cleaning access. A slow, controlled start-up helps the transmitter establish zero and prevents a cold slug from overloading the pump.

Questions to send with an inquiry

• Fluid name, density, and viscosity versus temperature
• Normal, minimum, and maximum mass or volumetric flow
• Operating pressure and temperature
• Pipe size, connection standard, and cleaning method
• Required output, area classification, and accuracy
