Selection principle

The medium decides the meter

Viscosity, flow profile, and operating environment dictate which technology fits. A meter that performs well on clean water can drift or fail on slurry, steam, or a gas stream.

Selection criteria

Choose by medium type

Conductive liquids

Conductive process liquids, including water, slurries, and chemical solutions, are commonly measured with electromagnetic meters, provided the fluid conductivity and line pressure suit the instrument.

Gases and steam

Compressed gases and steam call for thermal mass or ultrasonic technology, since density and temperature change with pressure. Line conditions set the sensor physics for a reliable reading.

Viscous hydrocarbons

Viscous hydrocarbons and fluids with variable temperature are often better suited to Coriolis or positive displacement meters. Accurate line configuration also limits head loss and measurement drift.
