ONICON’s F-1000 Series is a family of insertion and inline style turbine meters flow meters that provide accurate, reliable flow measurement in a variety of applications. The F-1000 Series meters are suitable for use in pipes ranging in size from ¾ to 72” in diameter.
Each model utilizes ONICON’s patented electronic turbine rotation sensing system and unique low mass turbine design that is accurate over wide flow ranges with excellent low flow measurement capability
Features
• The Dual Turbine Advantage
Dual counter-rotating turbines with mirrored helixes reduce the effects of the most common type of flow distortion, the swirl caused by bends and elbows. This reduces the upstream straight run requirements in some applications.
• Programmable with Built-in Diagnostics
The USB interface makes field programming simple. Advanced diagnostics provide real-time data from the meter
.• Excellent Long-term Reliability
Patented electronic sensing is resistant to scale and particulate matter. Low mass turbines with engineered jewel-bearing systems provide a mechanical system that virtually does not wear.
• Simplified Hot Tap Insertion Design
Allows for insertion and removal by hand without system shut-down for insertion meters
.• Unmatched Price vs. Performance
Individually wet-calibrated, highly accurate instrumentation at very competitive prices.
Applications
- Chilled water or hot water & water/glycol solutions for HVAC
- Domestic/municipal water
- Clean process water

CALIBRATION
Every F-1000 series meter is wet-calibrated using N.I.S.T.1 traceable standards. A certificate of calibration is provided with each meter.
THREE DIFFERENT OUTPUT VERSIONS
Frequency & Scaled Pulse/Alarm Outputs
This version provides a high-resolution frequency output and a scaled pulse output for totalizing flow. The frequency output allows for connection to ONICON Btu meters or displays. The scaled pulse output may also be configured as an alarm.
Frequency, Analog & Scaled Pulse/Alarm Outputs
This version provides a high-resolution frequency output, an analog output for flow rate and a scaled pulse output for totalizing flow. The frequency output allows for connection to ONICON Btu meters or displays. The scaled pulse output may also be configured as an alarm.
Frequency, Isolated Analog & Scaled Pulse/Alarm Outputs
This version provides a high-resolution frequency output, an isolated analog output for flow rate and a scaled pulse output for totalizing flow. The frequency output allows for connection to ONICON Btu meters or displays. The scaled pulse output may also be configured as an alarm.
