Ideal for exhaust gas measurement. Continuous purge type polynomial Pitot tube bar flow tube.
Continuous purge set system
To prevent clogging of the measurement holes, which is a weakness of the Pitot tube, continuous purging is performed during measurement to prevent blockages. It is optimal 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), methods that utilize pressure differences before and after a restriction mechanism, such as orifices, flow nozzles, Venturi tubes, and Pitot tubes, are 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. JMS Co., Ltd. provides a comprehensive service from planning, development, design, manufacturing, to maintenance as a specialized manufacturer of polynomial Pitot tubes.

basic information
The "polynomial Pitot tube" is not a throttling structure like an orifice or a venturi, allowing for very low permanent pressure loss. With multiple total pressure measurement ports and static pressure measurement ports provided, it can measure the average flow velocity in the piping and detect stable flow rates. To prevent clogging of the measurement ports, which is the biggest weakness of the Pitot tube, the Pitot tube sensor performs continuous purging during measurement.

Applications/Examples of results
The "polynomial Pitot tube" Barflow tube allows for flow rate and velocity measurement with low pressure loss. Therefore, it is widely used for exhaust gas measurement and other applications where energy savings are desired in the operation of factories and plants. It has numerous achievements 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 the measurement of the average flow rate 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.

Company information
JMSS Co., Ltd. was established in July 1976 with the keyword "environmental measurement." Since then, as a pioneer in environmental measurement in Japan, we have contributed to domestic environmental measures by initially importing excellent measuring instruments from overseas and then engaging in domestic manufacturing. We have also expanded our business to include energy-saving and plant corrosion prevention equipment as an extension of environmental measurement. In September 2003, we obtained ISO 9001:2000 certification (updated to ISO 9001:2015 in September 2021) (LRQA Limited). We promise to further enhance customer satisfaction with our products and services. We position compliance with laws and regulations as our top priority and are committed to advancing as a company to realize our motto, "Make Japan Beautiful."
