모델구분

• KOI : Glass tube rotameter for mounting on panels
  
• KOA : Glass tube rotameter for mounting on panels(PVC Type)
  

특징

• No need for straight pipe secteion upstream
  
• Can be used for liquid, gas and steam
  
• Low cost compared to other types
  
• Ease of installation and replacement
  
• Chemical compatibility
  
• Wide selection of materials(306 SS, 316 SS, Metal, etc.)
  

All the meters are calibrated accurately before shipment and shipped with test and calibration report to ensure the accuracy of the meter. The scales are inscribed with easily visible marking and can use the unit of the customers choice(index, percentage, actual flow(cm3/h, SCFM, etc.))

Meters that exceed the standard flow ranges can also be manufactured.

As standard, the meters are delivered with 1 year of warranty.

설치상 유의점

• In normal cases, no straight run upstream is not required because the meter is not affected by the flow profile. But when there's pipe bend or control valve upstream, at least 1 length of the meter should be secured upstream to avoid higher reading than actual flow.
  
• When a valve is installed close to the inlet of the meter, the float can be unstable and unable to indicate the flow accurately. Therefore, for liquids, the valve should be installed downstream of the meter and for gases, because they are compressible, the valve can be installed either downstream or upstream as long as the pressure can be maintained stable. But this doesn't apply to the valves attached to the meters by us because the flow is calibrated with the valve.
  
• Because the meter relies on the gravity of the float for measuring the flow, it is critical to install the meter vertically within 1º tolerance.
  
• Places where there's vibrations should be avoided
  
• The piping should be securely fastened in order not to induce stress to the meter.
  
• It is recommended to have by-pass pipe for recalibration or replacement works..
