Flowmeter > O Series [0-1000]




O-1000is 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 metal 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
· High press. and temp. acceptable thanks to metal tube flowmeter
· No Utility supply needed for local indication.
· Alarm contact(s), Analog output or Totalaizer are optionally available
