Onicon F-5501 Thermal Mass Flow Meter

F-5500 Thermal Mass Flow Meters provide direct standard volumetric flow measurement of gases without the need for temperature and pressure compensation. Both inline and insertion versions of the flow meter are available. The insertion design allows for easy insertion or removal from the pipe without the use of special tools and without disrupting flow. Inline meters are ideal for pipes less than 1½” in diameter. The low maintenance design is provided ready-to-use without the need for field programming.

The F-5500 flow meter includes a bright, easy-to-read user interface/display that provides rate and total data. The standard version of the meter is provided with a 4-20 mA analog output and an RS485 interface that is field configurable for BACnet® MS/TP or Modbus® RTU. A second output signal configuration is available that includes a 4-20 mA output for flow rate and a scaled pulse output for totalization or alarm indication.

F-5501 Standard Features

Highly Accurate

Proprietary digital control sensing circuitry is very stable and yet responsive to changes inflow. This design allows for accurate flow measurement over a very wide operating range (over 1000:1 for the inline version). It also makes the meter ideal for measuring low flow rates. Each meter is individually calibrated and is accurate to within ± 1.0% of reading for standard natural gas applications.

Ideal for Retrofit Installations

The insertion style meter can be hot-tapped into existing systems without interrupting gas service.

Low Maintenance

No moving parts and durable construction provide years of trouble-free service.

Simple Installation and Commissioning

Each thermal mass flow meter is factory-programmed for the specific application and ready for use upon delivery.
