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.

What is a Hydronic System and What is Needed to Balance it?

A hydronic system is a system designed to circulate chilled or hot water with the connections between piping and terminal units (heating and/or cooling devices). Most hydronic systems are closed and are usually made in a series loop. In addition to pipes and terminals, valves are placed in this series as a port to balance the differential pressure in the system. The balance of this type of system is often referred to as hydronic or hydraulic balancing. Continue reading “What is a Hydronic System and What is Needed to Balance it?”

Reducing Lead in Animal Watering Systems

One of the most harmful and common substances to greatly affect people’s health is lead. Lead is a carcinogen which can be found in some percentage of most everyday materials. Varying forms of lead exposure can come from paint in older homes, dust, soil, and drinking water. To avoid health risk, individuals should take precautions to reduce or eliminate the possibilities of exposure. Ensuring and minimizing livestock and poultry exposure to lead contaminants helps to reduce human exposure via the food supply. Continue reading “Reducing Lead in Animal Watering Systems”
