Its long form factor provides robust sampling in a variety of test rigs while resisting corrosion and wear in demanding tests.
Sorand Flow Meter 0.5-5 GPM
The Sorand inline flowmeter is designed for gas and liquid pipelines with a 0.5-5 GPM (1.8-18 LPM) capacity. It features a clear scale for easy reading and a durable plastic shell that resists breakage. The G1/2″ port size and straightforward inline installation make it suitable for water testing, chemical demonstrations, and basic flow measurement projects where quick, readable results are needed.
Fluke PT12 Pitot Tube
The Fluke PT12 Pitot Tube is built for precision in air velocity measurements, designed to work with Fluke 922-based airflow meters. It emphasizes pressure sensitivity to aid in accurate data collection, making it a staple for professionals who require dependable measurements in laboratory or field environments. Durability and compatibility with calibrated instrumentation are key strengths for this tool.
Garosa LZB-3 Glass Tube Flow Meter
The Garosa LZB-3 glass tube flow meter is designed for measuring 10-100 mL/min flow rates in liquids. It features a transparent acrylic panel for easy reading and a metal barb connector for hose attachment. This model is suitable for educational demonstrations, small-scale experiments, and precise liquid flow monitoring where a visible, graduated display enhances accuracy.
Buying Guide
- Intended medium: Pitot tubes primarily measure air pressure changes for airspeed; flow meters focus on liquid or gas flow in pipelines. Choose a model designed for your target medium to ensure compatibility and accuracy.
- Connection compatibility: Check port sizes (e.g., G1/2″, 6 mm) and mounting options to fit your setup, whether it’s a drone, wind tunnel, or lab bench.
- Reading clarity: Look for clear scales or digital readouts, especially in dynamic environments where quick interpretation is needed during tests or flights.
- Material and durability: Stainless steel and high-quality plastics resist corrosion and wear in harsh environments; glass and acrylic meters offer visibility but may be fragile.
- Calibration and compatibility: Some meters are designed to work with specific controllers or meters (for example, Arduino-based systems or Fluke instruments). Verify compatibility with your existing equipment.
- Application scope: For aerodynamics testing, choose pitot-static or differential pitot designs. For liquid flow tests, inline meters with readable scales are often preferred for quick, repeatable measurements.
- Maintenance: Consider ease of cleaning, especially in liquid applications where deposits can affect readings. Some meters are easier to disassemble for calibration checks.
- Budget versus accuracy: Higher-precision tubes and meters tend to cost more but deliver more reliable data, essential for professional or critical testing scenarios.
In selecting a pitot tube flow meter, users should weigh the balance between compatibility with flight controllers, reading clarity, and the type of medium to be measured. The reviewed options span aviation-oriented pitot sensing to inline flow meters for water and gas, offering a spectrum of accuracy, durability, and ease of use for hobbyists, researchers, and professionals alike.
