PCE Instruments PCE-HVAC 2 Anemometer

Tailpipe anemometer for high flow rates with Pitot tube for flow speeds up to 80 m/s / also detects differential pressure, volume flow, temperature / with data memory / software for real-time transmission including 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 and precise determination of high air speeds of up to 80 m/s. When measuring the flow speed, this tailpipe anemometer can be used with different units (m/s, knots, km/h, mph, ft/min). The 33.5 cm long Pitot tube with a diameter of only eight millimeters, which is mounted on the tailpipe anemometer, allows it to be used in confined work areas, small openings and pipe systems. The manufacturer PCE Instruments has equipped the measuring instrument with a few practical functions, which make it versatile. To mount it on a tripod, the tailboom anemometer has a thread on the underside. In this combination with two free hands, the user has greater flexibility in handling the tailpipe. The two pressure hoses of 85 centimeters each are attached to the upper side of the tailpipe anemometer and can then be connected to the L-shaped Pitot tube. In order to be able to read the measurement results optimally even under unfavorable light conditions, the manufacturer has provided the tailpipe anemometer with a large, backlit LC display. The internal measured value memory of the tailpipe anemometer offers storage options for up to 99 measured values per parameter. In this way, the collected data can be stored and retrieved at any time. In addition, the tailpipe anemometer allows maximum and minimum values to be stored. The anemometer has a convenient data hold function so that the last measurement results can be read again. A real-time measurement can be carried out via the USB interface of the tailpipe anemometer in combination with the software included in the delivery. In order to protect the battery, the manufacturer has equipped the measuring device with an auto-power-off function. The tailpipe anemometer switches off automatically after a short time when not in use. Application areas Pitot tube anemometer Pitot tube anemometers are preferably used in air conditioning and ventilation technology. They are ideal for determining the flow speed in ventilation ducts, for example. Its versatile functions make PCE Instruments' tailpipe anemometer indispensable in many other applications in trade, industry or in determining high wind diapers. The robust measuring device guarantees high measuring accuracy with simple handling with an ergonomic housing and illuminated display. PCE Instruments' Pitot Tube Anemometer is flexible and provides precise results even under difficult environmental conditions. The resistance of the robust, metallic dust tube probe to mechanical load is another plus. These features make the meter a reliable companion for technicians, installers and experts. Tailpipe Operation of the tailpipe anemometer consists of two essential components. This includes a differential pressure gauge and a tailpipe, which is also known as a Prandtl pipe, a pressure probe or a Pitot pipe. The tailpipe (Pitot tube) is a mostly L-shaped metal tube, which is provided with a hole on the front side. On the side, there are additional circular holes offset by 90°. Small passages in the metal tube pass the pressure applied to the holes to the differential pressure gauge, allowing the differential pressure to be measured between total pressure and static pressure. To measure the air speed with the tailpipe anemometer, the tailpipe is aligned parallel to the direction of flow and opposite to the direction of flow. The total pressure generated at the front opening is composed of static pressure and dynamic pressure. The static pressure is measured via the side holes. The difference between total pressure - 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 velocity of flow according to the Bernoulish equation. The tailpipe anemometer is therefore ideal for determining wind speeds. Accessories / Service as accessories for the PPCE-HVAC-2 tailpipe anemometer are available from the manufacturer PCE Instruments suitable stainless steel tailpipes in different lengths and diameters. PCE Instruments also offers the ISO calibration certificate CAL-AM for anemometers, wind gauges or wind sensors for compliance with DIN ISO 9000. Calibration certificates are issued specifically for customers, and annual recalibration can also be performed via PCE Instruments.
