U.S. imports of instruments & apparatus for measuring or checking liquid flow or level (HS 902610) totaled $87.5M in August 2026, imported from 75 countries.
Importers of Instruments & Apparatus for Measuring or Checking Liquid Flow or Level paid $7.2M in duties in August 2026, an effective tariff rate of 8.20% of the $87.5M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataFlow meters and liquid-level instruments — including electromagnetic, ultrasonic, Coriolis, and differential-pressure types — serve as critical process-control inputs across oil and gas, water treatment, chemical processing, and food manufacturing. Mexico leads US imports under this heading, with Germany and Canada also major sources; Germany's prominence reflects its deep concentration of precision flow-measurement OEMs. The US schedule distinguishes electric flow meters (9026102040), other electric liquid-measuring instruments (9026102080), non-electric flow meters (9026104000, 9026105000), and liquid-level instruments (9026106000, 9026107000).

An ultrasonic clamp-on flow meter that operates electrically and measures liquid flow would generally fall under 9026102040 as an electric flow meter for measuring or checking the flow of liquids. The 'clamp-on' installation method does not change the classification; what matters is that the instrument's principal function is liquid flow measurement and that it operates electrically. Importers should confirm the instrument's measurement medium (liquid vs. gas) since gas flow meters fall under a different heading (9026.20).
CBP distinguishes Coriolis flow meters — which measure mass flow rate as a process variable — from weighing instruments, which measure static or batch weight. The key documentation is the manufacturer's specification sheet confirming the instrument measures continuous mass flow rate (expressed in units such as kg/hr or lb/min) for process control, rather than batch or static weighing. Marketing materials, calibration certificates referencing flow-measurement standards, and any applicable CBP binding rulings for the specific model strengthen the 9026.10 classification.
