#Dwyer anemometer series#
The air velocity transmitters, Series AVUL and AVLV, are examples of hot-wire anemometers with additional features and enhancements. The Dwyer Model 471B Thermo-Anemometer Test Instrument is a versatile dual-function unit that quickly and easily measures air velocity or volumetric flow. This process is most commonly achieved using a wheatstone bridge circuit. The difference in power between the known constant and the effects of the air which is moving through the process, trying to drive the temperature down on the velocity sensor, can then be correlated back to an air velocity. The extruded aluminum housing of the 471B1 fully.456. The second sensor, the velocity sensor, is heated to an elevated temperature which is then cooled by the air flow in the process. A stainless steel probe is included, which has a comfortable hand grip and etched insertion depth marks. The first sensor, the temperature compensation sensor, measures the actual process media temperature inside of the duct or pipe. Typically, hot-wire anemometers are configured with two separate sensors. 485-1 Anemometer Details Options - Range Temperature Limits:Process: -40 to.
#Dwyer anemometer plus#
As the air moves over the wire, it causes a loss of temperature in the wire and removes some of the wire’s heat energy. Dwyer® Thermo-Anemometer Test Instrument, 471B-1, Measures Air Velocity and Temperature. The Dwyer 471B Digital Thermo Anemometer is a versatile dual function instrument that quickly and easily measures air velocity or volumetric flow plus air temperature in imperial or metric units. Dwyer - 485-1 Anemometer Daily Rate Weekly Rate 4-week Rate Daily Rate 32. He is also accredited for King’s Law, which mathematically describes heat transfer in air flows using a heated wire. Compact meter is ideal for HVAC inspection, energy audits, and balancing applications. Includes hard carrying case, battery, and instruction manual.

#Dwyer anemometer portable#
The initial term and first “hot-wire anemometer” was developed back in 1914 by Louie Vesso King. Looking for Anemometer, 0 to 6000 fpm Find it at ®. Dwyer VT-200 Vane Thermo Anemometer is a low-cost portable air-conditioning/heating anemometer or control of fan operation, blowers, and a Local Venting. Some of this instrumentation has a simple construction (Pitot tubes, for example) while others are more complex, such as hot-wire anemometers. Dwyer Instruments offers a multitude of sensors for monitoring air velocity in HVAC systems.
