Micro Manometer with Pitot Tube - PCE PFM 2
micro manometer to accurately measure air flow with Pitot tube
with memory and software for data processing / display with backlight / simultaneous indicator of air flow and speed, pressure and environmental temperature

The PCE PFM2 Micro Manometer with Pitot tube is used to accurately determine differential pressure as well as the air flow and gas velocity. The PCE PFM2 Micro Manometer is a useful device to determine high flow velocities. The PCE PFM2 Micro Manometer can also measure ambient air temperature. It has an internal memory for 99 measured values for each parameter. The measured values can be accessed via the display. These measured data can be transferred to a computer with the help of the optional infrared interface (with the included USB adapter and software). With this device you will be able to perform measurements in small places, little holes, tubes or pipes. The PCE PFM2 Micro Manometer with Pitot tube can be used in the industrial sector as well for professional use. At the following link you will find the micro manometer which will suit your needs.

 - Air Flow: m³/min ft ³/min

 - ISO calibration and optional certificate

Pitot tube principle:
Measurement of the static pressure "q" as the difference between the total pressure "pges" and the ambient static pressure. This principle is mainly used if the measured air has high temperature and high flow velocity. The stagnation tube is an essential instrument to determine air and gas flow velocity in pipes or air ducts. It consists of the combination of a Pitot tube to measure total pressure and a probe to determine static pressure.
