Straight Plastic Pitot Blade
This Straight Pitot Blade is a reliable piece of water flow testing equipment in water-based systems and fire protection equipment, including hose nozzles, fire hydrants, and more. Constructed with a durable plastic material, along with stainless steel tubing, this pitot blade is designed to be paired with any standard Pitot Gauge Handle. Featuring a 1/4 in. National Pipe Thread (NPT) connection, this blade threads to one end of the handle for a secure fit, and directs water toward a pressure gauge, providing pressure readings to help ensure proper function.
What is a Pitot Blade?
A Pitot blade, also known as a Pitot tube or Pitot probe when paired with a handle, is a device used to measure fluid velocity in a variety of applications. It is named after the French engineer Henri Pitot, who invented it in the 18th century.
The primary purpose of a Pitot tube is to measure the velocity of water by utilizing the principle of fluid dynamics. The device consists of a small tube or probe with an open end and a perpendicular blade, known as the Pitot blade. The open end of the tube faces the fluid flow, while the Pitot blade is positioned perpendicular to the flow.
When the fluid flows past the Pitot blade, it creates a pressure difference between the front-facing open end of the tube and the stagnation point on the blade. This pressure difference is known as the dynamic pressure and is directly related to the fluid's velocity. By measuring this pressure difference, the velocity, or flow, of the fluid can be determined.
