Work Smarter, Not Harder. Hydronic Balancing Simplified.

I often get asked, how should one simplify the hydronic balancing process? Since system blueprints will specify exactly where to set the balancing valves on the hydronic system to achieve proportional flow, it may seem simple enough for an installing contractor to determine the pressure drop through each circuit; however, hydronic systems are rarely installed exactly as designed.

Air Velocity and Flow Measurement with Pitot Tubes

Pitot Tubes Series 160, 166T, and 160S

Dwyer offers many styles of Pitot tubes. Pitot tubes are commonly used sensors for monitoring air velocity and flow rate in heating, ventilation, and air conditioning. Some examples include the: Stainless Steel Pitot Tube Series 160, Telescoping Stainless Steel Pitot Tube Series 166T, and “S” Type Stainless Steel Pitot Tube Series 160S.

Henri Pitot

Pitot tubes are based on Bernoulli’s equation, which states that 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.
