The 480 Vaneometer™ Swing Vane Anemometer is a highly durable and cost-effective instrument designed specifically to make the measurement of low air velocities more straightforward. With this single device, OSHA, EPA and other ventilation requirements for spray booths and fume, dust and smoke exhaust hoods can be checked quickly and efficiently – even by untrained personnel.
Small in size and low in weight, the 480 Vaneometer is ideal for carrying from one work station to another. But, should continuous monitoring be required, the device can be positioned with a versatile steel mounting bracket that comes supplied. The Vaneometer also features a tough ABS housing which is easy to clean and which incorporates a spirit level to help the user attain the most accurate readings.
Dwyer has available several types of wind meters. They include:

Our Series TIC Thermal Imaging Camera can be used for a range of applications, but the most common are the detection of air leaks in buildings and the prevention of plant and equipment failures caused by overheating.
How does it work?
The device translates infrared radiation into visual light on a bright 2.5” 160 x 120 resolution LCD. This allows the user to easily see heat contrasts and identify the source of a problem so that corrective measures can be taken. For increased differentiation among temperatures, the camera is able to automatically adjust the colour band for a narrower range of temperatures within the standard range of -20°C to +250°C.
As well as taking spot measurements, the camera can be set for isothermal, area or profile analysis.
Data is captured on an SD memory card for later evaluation.
Dwyer’s Series TSW Digital Temperature Switches bring the trusted, reliable TS family of temperature controls into weatherproof, installation-friendly enclosures for maximum protection against the elements and minimal set-up fuss. The same programming parameters as the Series TS2 and Series TSS2 means set up can be completed extremely quickly using the front keypad or by using the TS2-K configuration key. Multiple conduit knockouts give the installer flexibility in determining the best location for the conduit entry.
Series TSW switches feature a bright LED display that shows current output status and temperature measurements. Find out more by visiting Dwyer Instruments online.
DigiMag® is the name given to our Digital Differential Pressure and Flow Gauges designed for accurate monitoring of air and gas pressure or flow. They feature a 4-digit LCD that displays both metric and imperial units, and have a simple four button operation that reduces set-up time, simplifies calibration and ensures operator ease of use. The ability to operate on a 9-24 VDC line or a 9V battery makes these devices highly versatile. For further details and specifications, please visit Dwyer Instruments online.
Our Series VPI Rotary Valve Position Indicators have a compact, ruggedised design ideal for confined spaces and harsh operating conditions. These versatile units offer visual position indication and position limit control via two internal limit switches (mechanical or proximity), which may be precisely adjusted without tools. Mechanical models feature two SPDT switches, whilst proximity models have two solid-state inductive limit switches that eliminate the need for the cams to make contact. Series VPI indicators are IP67 rated, ensuring a high level of protection against the ingress of dust, dirt and moisture.
Dwyer’s Series EP1000 Electro-Pneumatic Controller brings together the highest quality instrumentation into one compact NEMA 4X enclosure for quick and easy installation. All that’s required is a supply pressure and voltage from a standard thermocouple, RTD, DC voltage or DC current input. Standard features include Self-Tune, Fuzzy Logic, fully adjustable PID and Auto/Manual Control. Series EP1000 controllers can be combined with the Dwyer Hi-Flow™ Valve for excellent process operation in industries like pulp and paper manufacturing, food and beverage processing, chemical and pharmaceutical production.
Dwyer’s Series MFS Magnetic Inductive Flow Sensor offers a compact, economic alternative to the conventional paddle wheel device. Unlike sensors with moving parts, the MFS can be applied in applications dealing with contaminated media as well as pure liquid. It provides reliable measurements, ensures a quick response time and does not interfere with the pipeline process. Also, any changes in temperature, density, viscosity, concentration or electrical conductivity will not affect output signal as they tend to in other devices. This, in addition to its long life cycle, makes the MFS perfect for accurate reversible gauging of conductive liquid flow in closed piping.
