With the installed tubing, the ANE-1 connects easily to any manometer or applicable pressure sensing device and is capable of measuring a wide velocity range. The higher the air velocity, the more current is required to maintain the second RTD’s temperature. Based on the current usage, the air velocity is calculated. The Model ANE-1 Differential Pressure Anemometer is a robust and durable bidirectional anemometer with no moving parts or sensing electronics. For constant temperature thermo-anemometers, two temperature sensors are installed at the end of the probe, typically resistance temperature detectors ( RTDs). One RTD measures the ambient temperature as a reference. The second RTD is continuously maintained at a constant temperature above ambient. Usually, a probe style sensor is made for insertion into ducts and pipes. Thermo-Anemometer Air Velocity Sensors Probe Style Sensor All three types have circuits that are based on trying to maintain a specific variable during the cooling effect based on Ohm’s Law. Thermo-anemometers offer good low flow detection, fast response times, and high rangeability of measurements. They are omni-directional, making them good for turbulent flows and easier to use than pitot tubes, but are more fragile than pitot tubes. Hot wire anemometers come in three basic types: constant current, constant voltage, and constant temperature. Compact meter is ideal for HVAC inspection, energy audits, and balancing applications.
Includes hard carrying case, battery, and instruction manual. 24 x 7 Service and support with periodic maintenance. The name is derived from the Greek root Anemos, meaning wind. There are many anemometer sensor types with one of the most popular being thermo, or hot-wire, anemometers for HVAC air velocity monitoring. Thermo-anemometers use a sensor element that is heated up beyond the ambient temperature. Airflow moving past the sensor will have a cooling effect that is directly proportional to the flow velocity.

#DWYER ANEMOMETER PORTABLE#
There are fixed duct mount styles for continuous monitoring, such as the Air Velocity Transmitters, Series 641, and portable insertion styles for testing, such as the Thermo-Anemometer Test Instrument, Model 471B and the Thermo-Anemometer Probe, Series AP2.Īnemometers are instruments used to measure wind speed or air velocity in meteorology and aerodynamics. OSHA, EPA, and other safety ventilation requirements for spray booths and at fume, smoke, and dust exhaust hoods can now be quickly checked, even by untrained personnel. Dwyer Instruments, Inc. offers many air velocity measuring products that use thermal or hot-wire sensors as the sensing element. Dwyer® Thermo-Anemometer Test Instrument, 471B-1, Measures Air Velocity and Temperature. The 480 Vaneometer Swing Vane Anemometer is a durable low-priced instrument specifically designed to simplify the measurement of low air velocities from 25 to 400 feet per minute.
