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.
Wall mount humidity sensors for building automation system (BAS) applications are produced and sold by several different companies and have a reputation of poor accuracy despite specifications from suppliers. There is a rational reason why these instruments appear to read outside of their stated accuracy, which in turn causes users to be frustrated with the results.
For decades, the municipal Water and Wastewater Market has been a focal point for many product lines associated with theMercoidbrand. With Dwyer’s ever expanding product lines we have been able to offer a diverse array of instruments to monitor and control pressure, level, flow, humidity, and data logging. A growing application with similar demands is landfill leachate pumping, where Mercoid has been able to successfully implement several products.
