Defination :


Air Rotameter in flow range for 0-300 LPM comes in a Reaor Back Connection, is a relatively simple & reliable instrument for measuring the continuous a Low flow rate indication of Air or Gases.


Manufacturing Process:

These Air Rotameter in flow range for 0-300 LPM  is a mfg in a tapered tube, drilled directly in acrylic body, with engraving the Flow rate. In Acrylic Body Rotameter, flow range is calibrated, engraved and colored with black or other colors on Acrylic body itself for long lasting durability.

Flow Control valve : These flow meters or Acrylic Body rotameter, are provided with the Flow control valve / Needle Valve, at the entry point of the rotameter, to control the flow of the fluid, as required.

End Connection : End-Connection comes as back or rear or Back connection, also known as an Inlet & outlet of the flow meter or Acrylic Body Rotameter, generally fitted with as a Screwed connection.The end connection comes as a Back or Rear connection, with its suitable line size required.

How it Works :
