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.
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.
