PCE Pitot Tube Anemometer PCE-HVAC 2

The PCE-HVAC-2 is a pitot tube anemometer from PCE Instruments for measuring differential pressure, air flow, air velocity and temperature. Thanks to its design, the anemometer equipped with an angled Pitot tube is particularly suitable for fast or precise determination of high air velocities of up to 80 m/s.

When measuring the flow velocity, this pitot tube anemometer offers a choice of different units (m/s, knots, km/h, mph, ft/min). The 33.5-centimeter-long Pitot tube attached to the pitot tube anemometer, with a diameter of only eight millimeters, allows it to be used in confined work areas, small openings and pipe systems. The manufacturer PCE Instruments has equipped the gauge with some practical features that make it versatile. So that it can be mounted on a tripod, the pitot tube anemometer has a thread on the bottom. This gives the user greater flexibility in handling the pitot tube with two free hands in this combination.

The two pressure hoses included in the scope of delivery, each 85 centimeters long, are attached to the pitot tube anemometer at the top and can then be connected to the L-shaped pitot tube. In order to be able to read the measurement results optimally even in unfavorable lighting conditions, the manufacturer has equipped the pitot tube anemometer with a large, backlit LC display.

The internal measured value memory of the pitot tube anemometer offers storage options for up to 99 measured values per parameter. Thus, the collected data can be stored and retrieved at any time. In addition, the pitot tube anemometer allows the storage of maximum and minimum values. So that the last measurement results can be read again, the anemometer has a practical data hold function. Via the USB interface of the pitot tube anemometer, a real-time measurement can be performed in combination with the software included in the scope of delivery. In order to conserve battery power, the manufacturer has equipped the measuring instrument with an auto power-off function. The pitot tube anemometer switches off automatically after a short time when not in use. Areas of application Pitot tube anemometers Pitot tube anemometers are preferably used in air conditioning and ventilation technology. They are ideal for determining flow velocity in ventilation ducts, for example. However, its versatile functions make the pitot tube anemometer from PCE Instruments indispensable for many other applications in trade, industry or for determining high wind speeds.

The robust measuring instrument with its ergonomic housing and illuminated display guarantees high measuring accuracy and easy handling. The pitot tube anemometer from PCE Instruments can be used flexibly and provides precise results even in difficult ambient conditions. The insensitivity of the robust, metallic pitot tube probe to mechanical stress is another plus. These properties make the measuring instrument a reliable companion for technicians, installers as well as experts. Pitot tube How it works The pitot tube anemometer consists of two main components. These include a differential pressure gauge and a pitot tube, which is also known as a Prandtl tube, pitot tube or Pitot tube. The Pitot tube is a metal tube, usually L-shaped, with a hole at the front. At the sides, there are further holes in the form of a ring, offset by 90°. Via small channels in the metal tube, the pressure applied to the holes is transmitted to the differential pressure gauge, allowing the differential pressure between total pressure and static pressure to be measured. To measure the air velocity with the pitot tube anemometer, the pitot tube is aligned parallel to the flow direction as well as against the flow direction. The total pressure generated at the front opening is composed of the static pressure and the dynamic pressure. The static pressure is measured via the lateral holes. The difference between the total pressure and the static pressure is used to determine the dynamic pressure with the connected differential pressure gauge. The dynamic pressure is based on a velocity component which can be converted into the flow velocity according to the Bernoulli equation. The pitot tube anemometer is therefore ideally suited for determining wind speeds.
