FLOW SYSTEMS has designed and engineered a unique solution (hardware and software) that combines Instrumentation, Data Acquisition and Control, Computation, Monitoring and Data Logging (Remote or Local) to meet the needs of the high-end flow measurement user. 

The data acquisition, control subsystems and all instrumentation are standard, readily available Commercial Off-The-Shelf (COTS) items. This ensures that servicing or replacement of any item can be achieved in a timely manner, providing high-availability for the test system.

Multiple Sonic Nozzle Arrays: The FC500 is the first commercially available flow computer that will accommodate using combinations of Sonic Nozzles configured in a Multiple Sonic Nozzle Array. This configuration requires that the user provide both compressed air and 24vdc power to actuate the solenoid valves, which are supplied by FLOW SYSTEMS. Now users may change the effective Sonic Nozzle throat diameter automatically via the Monitoring Software. The FC500 can interface with up to 15 Sonic Nozzles, thus offering a 32768:1 range in throat area.  This device is also offered as a stand-alone Flow Controller --a control valve and flowmeter in one package.  Optionally, Automated Pressure Regulation is available to increase both range and resolution.

The FC500 also works single Sonic Nozzles and Sub-Sonic Venturis. For those users requiring increased accuracy or advanced functionality, the FC500 is a superior choice over the FC175. Also, the instrumentation is enclosed in the FC500 and is therefore better protected.

Configuration / Monitoring Software:

The FC500 software was developed using National Instruments™ LabVIEW™ and uses an Ethernet connection to communicate with the FC500. This package gives the user the following functionality:

Test Set-up Screen:

Configures the FC500 for meter type, fluid, and units.

Flowmeter Configuration:

Calculations for Sonic Nozzles are in accordance with ASME MFC-7M / ISO 9300. 
Computations for Sub-Sonic Venturis meet the requirements of ASME MFC-3M / ISO 5167.

Data Monitoring and Logging:

Data may be logged into the internal memory of the FC500 automatically at a user-defined interval or manually by depressing the "Log Data" button on the front panel. The FC500 can store 3Mb of internal data in the base configuration. Optionally, a 11Mb data buffer is also available.

Flow Totalizing / Batching: Allows the user to Start, Stop, Clear and Log Batch data.

Remote data logging requires an Ethernet connection to the FC500.

Calibration Assistant for Maintenance of Internal Instrumentation:

Configuration of Outputs:



Two independent analog output (4 to 20ma dc) channels which may be configured for
remote monitoring of flow rate or other variables such as pressure or temperature by
another device or data logger.

Two independent digital outputs (24vdc, <400 ma each) may be configured to indicate specific conditions that can be sensed by another device.

Optional Internet Support and Diagnostics:

Allows FLOW SYSTEMS to observe and / or control a system remotely for training, optimization, or troubleshooting purposes. Requires a temporary, high-speed data line.

SPECIFICATIONS:

Accuracy

The FC500 uses a 16-bit data acquisition system to measure all analog inputs. The following tables state, percent of reading, mass flow accuracy for both available meter types and corresponding instrumentation configurations.
