Products classified under HTS 9026.90.40.00
Electromagnetic Flow Meter Sensor Head
The sensor head of an electromagnetic flow meter measures conductive liquid flow rates by detecting voltage induced in a magnetic field. It falls under HTS 9026.90.40.00 as a dedicated part of flow meters, essential for accurate volumetric measurement in industrial pipelines. This component interfaces directly with process fluids and requires calibration compatibility with the main meter body.
Turbine Flow Meter Rotor Assembly
Precision-machined rotor blades and shaft assembly for turbine flow meters that rotate proportionally to fluid velocity for flow rate measurement. Classified under HTS 9026.90.40.00 as a core internal part of flow meters used in hydrocarbon and chemical processing. Designed for high accuracy in clean, low-viscosity liquids with magnetic pickup compatibility.
Ultrasonic Flow Meter Transducer Pair
Pair of piezoelectric transducers for clamp-on or inline ultrasonic flow meters that transmit/receive acoustic signals to calculate flow velocity via transit-time difference. HTS 9026.90.40.00 covers these as anemometer/flow meter parts for non-invasive pipe measurement. Temperature-compensated for custody transfer accuracy in gas/steam lines.
Heat Meter Flow Sensor Cartridge
Replaceable cartridge containing turbine or ultrasonic sensor for district heating/cooling heat meters that measure energy consumption via flow and temperature differential. Falls under HTS 9026.90.40.00 as part of heat meters incorporating liquid supply meters. MID-approved for billing accuracy in HVAC systems.
Anemometer Wind Direction Vane Sensor
Potentiometer-based vane sensor assembly for cup anemometers that measures wind direction by rotational angle in meteorological stations. HTS 9026.90.40.00 includes anemometer parts for air velocity/gas flow monitoring. IP65-rated for outdoor extreme weather exposure.
Coriolis Flow Meter Vibration Tube
U-shaped vibrating tube assembly for Coriolis mass flow meters that detects flow rate via Coriolis force-induced phase shift. Classified HTS 9026.90.40.00 as precision flow meter part for mass/volume measurement in pharmaceuticals. Hastelloy C-22 construction for corrosive fluids.
Thermal Mass Flow Meter Capillary Sensor
Heated capillary tube sensor for thermal mass flow meters using heat transfer principles to measure gas mass flow rates. HTS 9026.90.40.00 part for clean gas applications like semiconductor manufacturing. Platinum RTD elements for temperature compensation.
