Ideal for exhaust gas measurement. Continuous purge type polynomial Pitot tube bar flow tube.
Continuous Purge Set System
To prevent clogging of the measurement hole, which is a weakness of the Pitot tube, continuous purging is performed during measurement to prevent blockages. It is ideal for measuring flow rate and flow velocity in large-diameter flues.
Flow measurement is one of the most important measurement items in the field of industrial measurement. When measuring the flow rate of fluids (liquids and gases), a method that utilizes the pressure difference before and after a restriction mechanism, such as an orifice, flow nozzle, venturi, or pitot tube, installed in the pipeline through which the fluid flows, is most commonly used in industrial measurement and its automatic control. Accurate and reliable flow measurement leads to effective plant operation, efficient energy use, environmental conservation, improved safety, and overall cost reduction. The specialized technology for selecting and installing flow meters ensures smooth plant operation and prevents unexpected shutdowns and troubles. JM Systems Co., Ltd. provides a comprehensive service from planning, development, design, manufacturing, to maintenance as a specialized manufacturer of polynomial pitot tubes.
Inquire About This Product
basic information
The "polynomial Pitot tube" or "Barflow tube" is not a throttling structure like an orifice or venturi, allowing for very low permanent pressure loss. It is equipped with multiple total pressure measurement ports and static pressure measurement ports, enabling the measurement of the average flow velocity in the piping and detecting stable flow rates. To prevent clogging of the measurement ports, which is the biggest weakness of Pitot tubes, the Pitot tube sensor is continuously purged during measurement.

Applications/Examples of results
The "polynomial Pitot tube" Barflow tube allows for flow rate and velocity measurements with low pressure loss. Therefore, it is widely used for exhaust gas measurements in factories and plants where energy conservation is desired. It has many applications in waste treatment facilities, sewage treatment plants, steelworks, chemical plants, and more.
Detailed information
-
The biggest weakness of the Pitot tube flow meter, which is the clogging of the measurement orifice, is resolved by the purge system. To enable average flow measurement within the piping, multiple measurement orifices are provided, and purge air is continuously supplied to the Pitot tube flow meter during measurement, allowing for measurements to be taken without being affected by clogging or corrosion from dust, mist, or particulates.
