Onicon F3500 Insertion Electromagnetic Flow Meter

Description

Onicon F3500 Insertion Electromagnetic Flow Meter 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, 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.

Onicon F3500 Insertion Electromagnetic Application

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