F-4600 Wetted Ultrasonic Inline Flow Meter

Brand: Onicon

ONICON's F-4600 Inline Flow Meters are designed to accurately measure the flow of water and water glycol solutions in small pipes. Meters are available for 1/2” to 2-1/2” diameter pipes. The no-moving-parts design operates over a wide flow range with excellent low flow performance.

The low cost design is provided with threaded process connections, a 4-20 mA analog output and a scaled dry contact pulse output for totalization.

*Optional integral LCD display with BACnet MS/TP or MODBUS RTU is available. LCD display can be mounted up to 5 feet away from flow body for visibility.
Features
  • Reliable No-Moving-Parts Design
  • The F-4600 incorporates a pair of wetted ultrasonic transducers that face each other directly in the flow tube. This configuration maximizes signal strength and long term reliability.
  • Highly Accurate Over a Wide Flow Range
  • The flow tube design and direct beam path configuration is optimized for water and water/glycol solutions. This allows for improved accuracy at low flows.
  • Easy to Install in Limited Straight Runs
  • The F-4600 has an innovative flow tube design that simplifies installation by allowing for limited straight pipe upstream and downstream of the meter in most installations.
  • Simplified Installation and Commissioning
  • Each F-4600 is fully configured and programmed before it leaves the factory and is ready for use upon delivery.
