F-4600 Inline Flow Meter

New at ONICONONICON'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 ½” – 2½” 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 4-20mA analog output and a scaled dry contact pulse output for totalization.
*Optional integrel 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.

Typical Applications
The F-4600 inline flow meter is ideal for chilled water, hot water, domestic water, condenser water, steam condensate and boiler feed water.

Standard 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.
