OSK22SB101 Air flow meter with the ventilated commutator

Air flow meter with the ventilated commutator
Application
      1. OSK22B101 Porous pitot tube air flow meter with ventilated commutator (Air flow meter that measures duct inner air flow)
      2. Speeding up the saving energy and lower cost by reducing the carrying power (Promoting enviromental management)
      3. - Controlling the optimal volume and balance of ventilated air and air from outside
     
        - Controlling the optimal volume of ventilated air of CAV・VAV system 
     
        - Maintenance-free 
     
        - Controlling the volume of air flow and providing the proper operation
     
      1. Stable quality of product
      2. - Controlling the air volume at the medical supplies production plant or laboratory
     
        - Clean room for production of semi-conductors or liquid crystall
     
        - Controlling the process of painting, coating and drying of high-function products
     
        - Controlling the air volume at surgeryroom, radiation materials storage of biohazard hospital
     
      1. Providing the safety of working atmosphere
      2. - Controlling the volume of air of equipment for elimination of bad smell or dust or VOC disposal equipment
     
        - Controlling the ventilated and exhausted air volume at the plants, incinerator, or sewer systems
     
        - Controlling the volume of air condition or ventilated/exhausted air at electricity generation plant
     
        - Controlling the air flow of facilities for flour mill or steelmaking
Features
    1. Compact design that includes rectification structure and sensor part inside the metal case
    2. By making the rectification structure, made the shape of lattice, the pressure loss and running costs are reduced
    3. Uses same method of pressure difference as at the pitot tube and orifice
    4. Sensor consists of 2 midair cylinders and opens measuring hole, checking the flow pressure at the upper (full pressure) and lower (static pressure) area
    5. Depending on the position of the hole, the high-precision measurement of Reynolds number area becomes possible
Effect
    1. The materials of the main structure are chosen from stainless steel or aluminium, galvanized steel plate, and etc. to applied for various usage
    2. Saving the space for installation:Due to the use of rectification lattice inside, the number of straignt tubes is reduced
    3. Compact design :By unifying the rectification lattice and sensor、the installation at the narrow space becomes possible
    4. Increased detection pressure difference:the detection pressure is 2-4 times bigger than of usual pitot tube and the rate of reading error becomes much lower
