Averaging Pitot Tube Flowmeter

Specifications

Averaging Pitot tube flowmeter

As an insertion-type flow meter, it is quickly and easily installed through a small hole drilled into a pipe or duct. As a mechanical device without electronics or moving parts, it doesn’t suffer from electronic drift or physical wear, making it a dependable, repeatable primary element requiring no periodic recalibration. Maintenance may be as simple as inspect and replace as needed.

Averaging Pitot tubes are most suitable for flow measurements of clean liquids, gases or steam.
The devices are not the best choice, however, for applications such as liquids with high viscosity, gases with low velocity, or where harmonic vibrations in the probe cannot be avoided (don’t be alarmed here — manufacturers screen applications for harmonic vibration). Also, multiphase fluids, such as a gas with significant amounts of entrained liquid or a liquid with entrained gas are not good applications for this technology. Finally, dirty gas or liquid flows can be problematic with the sensing ports on the averaging Pitot tubes. Purging systems can be used to reduce or eliminate blockage in some of these applications.

Averaging pitot tube flow meter is much cheaper than some other kind of flow meters.  If you instinctively choose a more expensive option than an averaging Pitot tube without knowing precisely what you need, you may get more range and accuracy than you really require and an additional expense you certainly don’t want.

Application:

BF10-500 series have good sealed capability. They are excellent in mearsuring high temperature and high pressure media, such as steam, H2,O2 and other flammable and explosive gas.
