*Specifications are subject to change without prior notice.

O-100 is series of Orifice bypass flowmeter. The flow through the main pipe is by -passed by an orifice plate. The bypassed flow is indicated by small sized glass tube variable area flowmete flow measurement through main pipe.

Main Applications

  • · Economical measurement even for large size lines.
  • · Any flow direction of horizontal, vertical including top to bottom possible.
  • · No Utility supply needed for local indication.
  • · Alarm contact optionally available.
