Tokyo Keiso O-1000 Series ORIFLO METER®
Made in Japan
Manufacturer: Tokyo Keiso
Model: O-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 flowmeter flow measurement through main pipe.
Features
- 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 Totalizers are optionally available
