Pitot Tubes

6 products

The pitot tubes collection offers precision instruments for measuring fluid velocity—especially air—in HVAC systems, ductwork, and ventilation environments. By leveraging differential pressure principles, these tubes capture accurate flow data for diagnostics, balancing, and performance analysis. Supplied in various lengths and diameters, they adapt seamlessly to different duct sizes and configurations. Paired with compatible manometers or pressure sensors, pitot tubes form essential tools for airflow measurement in mechanical engineering, building commissioning, and energy optimization applications.

Frequently Asked Questions

A pitot tube measures fluid flow velocity by converting the kinetic energy of the flow into pressure. In HVAC and industrial applications, it’s commonly used to measure air velocity and airflow rates in ducts, ventilation systems, and cleanrooms.

 A pitot tube works by capturing total and static pressure from a moving air stream. The difference between these pressures (called differential pressure) is used to calculate the flow velocity. It requires connection to a manometer or pressure sensor for accurate measurement.

Pitot tubes are widely used in HVAC, environmental testing, aerospace, fluid mechanics labs, and industrial process monitoring. They’re essential for airflow testing in ducts, fume hoods, and ventilation systems to ensure efficiency and regulatory compliance.

Yes, HK Calibrations supplies standard straight pitot tubes, S-type pitot tubes, and specialized models suitable for various airflow and gas flow applications. All models are available in different lengths and diameters to match your system requirements.

Yes, pitot tubes should be calibrated to ensure accurate flow measurements. HK Calibrations offers pitot tube calibration services using traceable reference standards to meet industry and NATA requirements, helping ensure reliable and audit-ready results.

Pitot tubes are typically used with manometers, micromanometers, or differential pressure gauges to measure airflow velocity and volume. HK Calibrations also offers compatible digital pressure meters and calibration services for complete measurement systems.

Pitot tubes offer accurate flow readings when properly aligned and used in steady, laminar flow. Accuracy depends on setup, calibration, and associated pressure sensor quality. For precise airflow monitoring, regular maintenance and calibration are recommended.
