ONICON F-5500 Series Thermal Mass Flow Meters

DESCRIPTION

ONICON’s F-5500 Series Thermal Mass Flow Meters mampu memberikan pengukuran flow yang akurat untuk material natural gas, udara bertekanan tinggi, dan industrial gas lainnya. Desain perangkat sensor mengukur mass flow secara langsung dan tidak membutuhkan tambahan tekanan atau kompensasi suhu dalam penggunaannya.

F-5500 tersedia dalam tipe inline maupun instertion dan dilengkkapi dengan interface yang mudah digunakan. Versi standar flow meter ini menggunakan 4-20 mA analog output dan interface RS485 yang kompatibel dengan BACnet® MS/TP or Modbus® RTU.  Konfigurasi signal output yang tersedia menggunakan 4-20 mA analog output dan sebuah programmable pulse output. Model pulse output nya juga tersedia dengan HART.

APPLICATIONS

Accurate sub-metering of natural gas & propane for:

• Tenant space usage
• Boiler efficiency
• Campus monitoring

Also ideal for monitoring:

• Compressed Air
• Medical gases
• Other industrial gases

FEATURES

BACnet MS/TP or MODBUS RTU –

The standard F-5500 includes an RS485 output that provides BACnet MS/TP or Modbus RTU. Data reported to the network includes flow rate and total, temperature

and elapsed time since reset.

User-Friendly Interface / Display – 

The bright, easy-to-read, backlit display and intuitive menu structure simplify page navigation and allow for field programming. Free utility software is also available for programming

and data logging.

Provides for Field Validation of Calibration –

F-5500 internal diagnostic functions include a zero flow calibration check. This fast, easy to perform, the test allows for field validation of the factory zero flow calibration. The utility software provided with the meter allows you to print a certificate validating the test results. Insertion Meters Can Be Installed Without Interrupting

Gas Service* –

ONICON’s hot tap design allows for installation without interruption to the gas service. The meter can also be removed for service without disrupting the flow.

Highly Accurate Over a Wide Operating Range –

Our proprietary direct digital control sensing circuitry is very stable yet highly 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.

Excellent Value –

ONICON insertion style meters are accurate, easy-to-use and reliable. They are also priced independently of pipe size. This makes them an excellent value, particularly in larger diameter pipes.

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.

* Installations must comply with federal, state and municipal building codes. Review all proposed combustible gas installations with your local code enforcement officials before attempting any installation.
