Flow Meter Use Case

Meter type Best suited for Typical applications Key advantages Limitations
Coriolis Liquids Gases Slurries Custody transfer of hydrocarbons & chemicals, pharmaceutical batching, food & beverage dosing, LNG measurement Measures mass flow & density directly; very high accuracy (±0.1%); handles viscous fluids High cost; pressure drop concern; not suitable for large pipe diameters; vibration sensitive
Thermal mass

Clean gases Air

Compressed air monitoring, natural gas sub-metering, HVAC balance, combustion air measurement, emissions monitoring Direct mass flow of gas; no moving parts; measures very low flows; low pressure drop Gases only; sensitive to contamination and coating; requires calibration per gas composition
Magnetic (Mag) Conductive liquids Slurries Water & wastewater, mining slurries, pulp & paper, food processing, chemical dosing No moving parts; unobstructed bore; handles solids & slurries; bi-directional; low maintenance Requires electrically conductive fluid (min ~5 µS/cm); not for hydrocarbons or gases
Vortex Steam Gases Clean liquids Steam distribution & energy metering, compressed gases, light hydrocarbons, district, heating and cooling Wide temperature range; no moving parts; handles steam well; long term stability Minimum flow velocity required; vibration sensitive; not for viscous, dirty, or two phase fluids
Clamp-on ultrasonic Clean liquids Non-invasive Retrofitting existing pipes, chilled/hot water circuits, district energy, temporary flow verification, hazardous or inaccessible lines Zero pipe penetration; no process shutdown needed; portable; works on wide range of pipe sizes Reduced accuracy on dirty or aerated fluids; pipe condition & wall thickness affect accuracy; signal attenuation on lined and corroded pipes
Doppler ultrasonic Dirty liquids Slurries Aerated fluids Wastewater & sewage, mining slurries, sludge lines, aerated process streams, portable spot-checking of problematic fluids Works where other ultrasonic meters fail; handles suspended solids & bubbles; non-invasive Requires particles or bubbles (>100 ppm); less accurate on clean fluids; not for custody transfer
