Average Flow Measuring Pitot Tube | AFMT
R5,220.00 – R11,549.00 ex vat
Average Flow Measuring Pitot Tube - Overview

The Average Flow Measuring Pitot Tube is a probe that is placed into the duct to measure flow. This is often used alongside a differential pressure transmitter in flow measurement. The various pressure detecting openings on the AFMT pick up the average flow inside the duct. AFMT then calculates the flow velocity by measuring the difference between dynamic pressure ∆P (total pressure and static pressure) and flow average velocity V. Conversion from data to flow rate happens quickly and accurately. This product is corrosion resistant, heat resistant, dust resistant, and anti-clogging. It is widely used in harsh environments such as exhaust gas emission, vacuuming, and dust wind speed calculation. Also used in ventilation and air-conditioning systems.

Average Flow Measuring Tube - Overview

The Average Flow Measuring Tube adapts the Pitot tube principle, where the Pitot tube and a differential pressure sensor are commonly used for flow measurement. It measures the differential pressure between the total pressure and static pressure of the fluid, allowing for the calculation of fluid velocity. The difference between total and static pressure is known as dynamic pressure, which results from fluid flow and is proportional to the square of the flow velocity. By measuring dynamic pressure, the fluid speed can be accurately determined. It features a multi-hole structure, which averages pressures from multiple points to better represent the actual flow profile within the pipe, ensuring stable and precise measurements. Applications include HVAC, Ventilation, Exhaust gas treatment, low and high flow measurement.
