9026.10.20.40 - Flow meters

This HTS category, 9026.10.20.40, specifically covers electrical flow meters designed for measuring or checking the flow of liquids. These instruments utilize electrical principles to determine the rate at which a liquid is moving through a system. Examples include electromagnetic flow meters, which operate based on Faraday's law of induction, and ultrasonic flow meters, which measure flow by analyzing sound waves. The key distinguishing feature is their reliance on electrical signals and components for the measurement process.

This classification is differentiated from its sibling category, 9026.10.20.80, which encompasses "Other" electrical instruments for measuring the flow or level of liquids. While both fall under electrical flow meters, the "Other" category would typically include electrical devices that measure liquid level or other variables not specifically defined as flow measurement, or electrical flow meters that do not fit the narrower scope of 9026.10.20.40 if such distinctions were made at a lower level.

As this is a leaf node within the HTS database, there are no further subcategories under 9026.10.20.40. Therefore, the focus is on the specific criteria that define electrical flow meters for liquids. When classifying goods under this heading, customs officials will look for instruments that are primarily designed for the continuous or intermittent measurement of liquid flow rates and employ electrical phenomena or circuitry in their operation.
