Model FC200


DESCRIPTION

Flow Systems introduces the lightweight and mobile Flow Computer model FC200.  The FC200 offers a greater economy than its FC500 counterpart, and is designed for applications requiring fewer features and a lower price.  The FC200 interfaces with single, manually interchangeable, Sonic Nozzles and Sub-Sonic Venturis.  Multiple levels of accuracy are available with highly repeatable results.

SOLUTION

This unique solution (hardware and software) combines Instrumentation, Data Acquisition and Control, Computation, Monitoring and communication with a local, customer-supplied personal computer or laptop.   Accurate Measurement via User-Friendly Controller and High System Availability are key features of this test instrument.

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.

The FC200 works with single Sonic Nozzles and Sub-Sonic Venturis. For those users requiring increased accuracy or advanced functionality, we suggest the FC500 model flow computer.

Configuration / Monitoring Software:

The FC200 software was developed using National Instruments™ LabVIEW™ and uses a USB connection to communicate with the FC200. This package gives the user the following functionality:

 


Test Set-up Screen:

Configures the FC200 for meter type, fluid, and units.

Real Gas Properties for most Gasses.



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.

Iterative Solution for Discharge Coefficient (Cd) based on Actual Calibration Data or Theoretical Models.

 

 

Data Monitoring and Logging:

Data may be logged automatically at a user-defined interval.

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


 

Calibration Assistant for Maintenance of Internal Instrumentation:


Optional Internet Support and Diagnostics:

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