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.

By simply inserting a porous pitot tube into the flue, it is possible to measure the flow rate and velocity of exhaust gases within the flue. Therefore, it enables low-cost measurement of exhaust gas flow rate and velocity without the need for extensive construction. The pitot tube has lower pressure loss compared to orifices and venturi meters, contributing to energy-saving operations for the entire plant. Our pitot tube flow meter, the Bar Flow Tube, is produced under a fully integrated system in our own factory, covering planning, design, procurement, manufacturing, inspection, and maintenance. We have established a management system that ensures customer satisfaction. We aim for the adoption of our Bar Flow Tube to assist in improving your processes.

JMS Co., Ltd. provides a comprehensive service from planning, development, design, manufacturing, to maintenance as a specialized manufacturer of polynomial Pitot tubes. We have a cumulative shipping record of over 10,000 units.

The Pitot tube has a rod-like shape. It is inserted vertically into the piping to measure flow rate. Holes are provided on the rod to detect total pressure and static pressure. By measuring the differential pressure (also called dynamic pressure), the flow velocity of the fluid flowing in the pipe can be determined. The multi-hole Pitot tube has multiple holes on the rod that comply with JIS B 8330, allowing for the measurement of average flow velocity. The two pressure sensing pipes that exit the Pitot tube are connected to the high-pressure and low-pressure sides of a differential pressure transmitter. The differential pressure is converted to flow rate through square root calculation processing by the differential pressure transmitter. It is often used for measuring exhaust gas flow rates in large-diameter ducts. Large-diameter ducts (300A or 500A and above) cannot be manufactured with orifice plates or are very costly, making the Pitot tube flow meter a strong option. Among flow meters, the Pitot tube is simple and relatively low-cost.

The "DynaFlow" is a pitot tube with an integrated rectifier that achieves a zero straight pipe length. By combining the sensor element and the rectifying element into one unit and directly connecting it to the duct, it can be installed in limited spaces. It can control the optimal airflow for various environments such as air conditioning and drying, leading to improved production efficiency through flow management. Additionally, it is designed utilizing the flow measurement technology developed over many years with pitot tubes. Experimental data collected from in-house wind tunnel facilities is also accumulated, providing backed data. 【Features】 ○ Available in all stainless steel specifications (SUS316, SUS304) → No concerns about corrosion issues from outgassing or corrosive gases ○ Compatible with square ducts/round ducts as per your request → Both flange and angle connections are possible ○ Domestic production allows for short delivery times For more details, please contact us or download the catalog.
