Pitot tube for flow velocity/flow rate measurement and control in all industries
Irie Co., Ltd.
About This Product
■Features and advantages of pitot tubes
- Low pressure loss reduces plant operating power.
-Easy to install in ducts. Also, there are no moving parts, making maintenance easy.
-Size, shape, and material can be selected.
- Low friction and excellent durability.
・It is not affected by the structure or components of the fluid and can be used for gases containing ducts. Also, it has excellent reproducibility.
■Principle of flow velocity/flow rate measurement using pitot tube
When a Pitot tube is placed in a flow of fluid, the flow is blocked in front of it and flows backwards, but there is a point at the tip where the flow velocity becomes zero. The pressure at that point is called total pressure (Pt) and is detected through the hole at the tip. The pitot tube also has a hole on the side, which detects the pressure of the fluid (static pressure Pt). A pitot tube detects total pressure (Pt) and static pressure (Ps), and calculates the flow rate and flow rate from the difference between the two (dynamic pressure or differential pressure Pd) using Bernoulli's theorem.
■Bernoulli's theorem
If a fluid has no viscosity, so there is no need to consider the effect of friction, and if it is not compressible and has a constant density, then the sum of the work done by the fluid's kinetic energy, potential energy, and static pressure is is constant.
■Method of measuring flow rate and flow rate using a pitot tube
Pitot tubes determine flow velocity and flow rate by detecting differential pressure (dynamic pressure), so they are used in combination with measuring instruments such as differential pressure gauges.
・Differential pressure gauge Measures and calculates differential pressure (dynamic pressure)
・Pitot tube type flow rate/flow meter Differential pressure (dynamic pressure) sensor and indicator (calculation) are integrated
・Output the transmitter differential pressure (dynamic pressure) and calculate it with the indicator
■Comparative testing and calibration with standard pitot tubes can be performed in the wind tunnel facility.
・We use a wind tunnel to conduct comparison tests with standard pitot tubes one by one.
・A pitot tube test report is attached.
・We also accept calibration of pitot tubes. (Paid)
・Calibration certificate (traceability system diagram) can also be issued upon request. (Paid)
