Dwyer Instruments, Inc. was recognized for excellence in product design in the 14th annual Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News Magazine (The ACHR News). An independent panel of contractors acted as judges in the contest that had 81 entries. Three Dwyer products stole the spotlight this year: the PredictAir™ Application Software; the Series AVUL, Air Velocity Transmitter; and the Series 490A-HKIT, Hydronic Differential Pressure Manometer. ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries.
Dwyer Instruments offers several flow measuring products that use a thermal sensing element.
Thermal dispersion flow sensors use a temperature element that is heated up beyond the media temperature. Based on calorimetry, the flow moving past the sensor will have a cooling effect that is directly proportional to the flow velocity. The heat is convected from the heated probe surface to the boundary layer of the fluid flowing over the heated surface. Continue reading “Thermal Dispersion Flow Switches”
Why is pressure sensor accuracy important? From a manufacturer’s point of view, the wrong sensor can cause expensive quality or efficiency problems. This is why it’s important to understand how manufacturers calculate accuracy and recognize what parameters to look at when comparing pressure sensors.
By understanding how manufacturers calculate accuracy, you will be able to make a more informed decision when evaluating pressure sensors. This ensures that the next sensor that you select will have the required accuracy at the right price for the application. Continue reading “Pressure Sensor Accuracy”
The Proximity Controls Division of Dwyer Instruments, Inc. specializes in both bulk level monitoring and valve position indication. Rarely do these two sides of the business intersect. That is until the engineers at Proximity Controls came across a challenge to improve an industry standard level sensing technology. Continue reading “Rotary Paddle Level Switches Re-Invented”
Dwyer Instruments, Inc. offers many types of flow measuring products, including electromagnetic flowmeters.
Electromagnetic flowmeters, often called magmeters, provide continuous flow indication of liquids via state-of-the-art electromagnetic technology based on Faraday’s Law. Continue reading “Flow Measurement with Electromagnetic Flowmeters”
