Glass Tube Type Oriflo Meter O-100 Series

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.

· 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.
