3
Scalable / Distributed Universal I/O

• Easily Expandable
• Build 10 to 1000s of point I/O systems
• Start small and expand in the future
• Reduce wiring and installation costs
• Locate I/O in any location
• Add I/O to new or existing DCS or PLC
  withoutmoving existing wiring
• Cost effective
• Reduce Spare Parts by stocking common universal
  I/O modules
• Very reliable hardware reduces maintenance costs
• Calibration held in each module
  simplifiescalibration procedures

Secure Redundant Data

• No lost data
• Measured data is storedin a local CF (Compact
  Flash)memory card
• Data will automatically backfill via FTPafter a
  failed network recovers
• Low operation cost
• System can run standalone without any
  operatorinteraction by FIFOing stored data on
  local CF memory card
• Large CF card will store data for a long period
  without operator intervention

Data via FTP
5
Network Capable

• Easy integration to existing systems
• Add I/O to an existing DCS without purchasing
  expensive I/O cards and DCS tags
• Add modern advanced communication capabilities to
  your existing PLC or DCS without complex
  engineering and integration costs
• Safe guard critical data by storing data locally
• Examples
• A-B SLC500, PLC5
• A-B ControlLogix
• Bailey Infi90
• Westinghouse
• DeltaV
• Yokogawa CS

Easy to Configure

• Dedicated PC is NOT required
• Everyone with internet access can view data
  without special software
• No annual software license costs
• View trend, digital alarm process data and log
  historical data in minutes
• Eliminate expensive configuration and integration
  costs
• Build control applications without hiring an
  integrator
• Control configuration is accomplished with
  readable math equations and logic statements
  (IF,THEN,ELSE,AND,OR,NOT)
• All configuration is handled via the DAQMASTER
  built-in webserver

I/O with High Accuracy, Stability Isolation

• Low operation cost
• One module can handle any application by
  measuring any signal from 20/-20mV to 100/-100
  V, plus DI contact or Level Inputs
• Calibration is held in each module and terminal
  blocks can be removed
• DAQMASTER will withstand accidental over voltage
  situation with 3700 VRMS (for 1 minute) and 600
  VRMS/VDC continuous isolation

Remove module without breaking 4-20mA loops. Take
the module to the shop for calibration.

Gas Flow Terminology

• AGA American Gas Association
• Industry research and marketing body that
  promotes standards
• Flow Computer
• Receives inputs from sensors and applies AGA
  calculations to record corrected flow rates and
  energy density
• Common flow sensors
• Orifice Plate
• Venturi-tube
• V-Cone
• Turbine meter
• Compressibility
• gas becomes more dense under pressure, requiring
  calculation of a compressibility factor (Z) in
  order to return it to Standard Temperature and
  Pressure (STP) volume.

MW100 AGA Gas Flow Computer Features

• DAQMASTER MW100
• AGA Gas Flow Computer Features
• Supports AGA 3 and AGA 8 methods
• One MW has (10) gas flow computation sets!
• Currently supports orifice and venturi sensor
  types
• AGA gas flow comes with Class I Div 2 model (/S8
  option)
• New software (MW180-2) used for gas flow setup

13
Backgroun AGA Reports and Methods

• AGA 3
• Corrected gas flow in conjunction with Orifice
  Plates and DP Sensors
• Density input is external input or fixed value.
• AGA 7
• corrected gas flow in conjunction with Turbine
  Meters, requires external input for density or
  fixed value.
• NX-19
• Older, less intensive corrected closed-form
  (non-iterative) gas flow calculation for natural
  gas compositions of up to 15 CO2 and N2.
  Supported by many flow computers.
• AGA 8
• Complex compressibility and density calculations
• Uses table look-ups and iterative sequences
• Compensates for higher inert composition and
  operating conditions.
• Accepted as most accurate

14
Background Characterization Methods

• All methods need operating P, T, and ACFH to be
  able to compute SCFH
• Detail Characterization
• Input complete breakdown by Mole of gas
  composition
• Gross Characterization Method 1
• Input specific gravity, CO2, and Heating Value
  (BTU/FT3)
• Gross Characterization Method 2
• Input Specific Gravity, CO2 , and N2
• MW100 Supports all three characterization types

How Gas Flow Computation is done in MW100

1. Use MVTool offline software to setup gas flow
   parameters
2. Download gas flow configuration to MW100 (this is
   a new step)
3. Use standard webserver configuration tools to
   program MW100
4. Add new math statements to access gas flow
   computation results
