F-3500 Series Insertion Electromagnetic Flow Meter


DESCRIPTION

ONICON Incorporated’s F-3500 series insertion electromagnetic flow meters are suitable for measuring electrically conductive liquids in a wide variety of applications. Each F-3500 provides a single analog output for flow rate, a high resolution frequency output to drive peripheral devices, a scalable pulse output for totalization, and an empty pipe alarm signal.

Two versions of the F-3500 are now available. The standard configuration F-3500 is suitable for pipe sizes ranging from 3” to 72” in diameter. The small pipe configuration F-3500 is suitable for pipes ranging in size from 1¼” to 2½” in diameter. Optional remote displays and BTU measurement systems are also available for both versions.

APPLICATIONS

• Accurate, reliable flow measurement for HVAC applications
• Ideal for monitoring open loop condenser water flow
• Hot tap design simplifies domestic water retrofit installations
• Cost-effective way to monitor flow in larger pipe sizes
• Suitable for use in water and water/glycol systems

CALIBRATION

Every ONICON flow meter is wet calibrated in a flow laboratory against standards that are directly traceable to NIST*. A certificate of calibration accompanies every meter.


FEATURES

Simple Installation and Commissioning - 
Factory programmed and ready for use upon delivery. 
Exceptional Performance & Value - 
Cost-effective insertion style design provides accuracy and reliability normally only found in more expensive full bore devices.
Excellent Long Term Reliability - 
Low maintenance, no-moving-parts flow sensing technology works well in difficult flow measurement applications such as open loop condenser water flow.
Highly Accurate Over a Wide Flow Range -
Highly efficient sensor design and continuous auto-zero function improve accuracy and
sensitivity, particularly at low flow rates.
Simplified Hot Tap Insertion Design - 
Standard on every insertion flow meter, this feature allows for insertion and removal by hand
without a system shutdown.
Ideal Solution for Retrofits - 
The innovative hot tap adapter design allows for wet tapping pipes without interrupting flow.
