A common flow measuring application is using a Magnehelic® Differential Pressure Gage with a Pitot Tube to measure velocity pressure. This velocity pressure can then be easily converted into velocity or flow rate. Continue reading “Custom Scales for Differential Pressure Gages”
Dwyer Instruments offers many styles of Pitot tubes, which are a commonly used sensor for monitoring air velocity and flow rate in heating, ventilation, and air conditioning.
Pitot tubes are based on Bernoulli’s equation, which states an increase in the speed of a fluid occurs simultaneously with an increase in dynamic pressure and a decrease in static pressure. Pitot Tubes sense the dynamic pressure of the fluid flow at a particular point and were invented by French Engineer Henri Pitot in the early 18th century.
