2. Basic Features Overview
DAQMASTER “MW100”
Basic Features –
FM Approved Class I Div 2
Gas Flow Computer with AGA3/AGA8
Scalable / Distributed Universal I/O
Secure Redundant Data
Network Capable
Easy to Configure
I/O with High Accuracy, Stability & Isolation
Built in web server

3. Scalable / Distributed Universal I/O
Easily Expandable
Build 10 to 1000’s 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 without moving 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 simplifies calibration procedures

4. Secure Redundant Data No lost data Low operation cost
Measured data is stored in a local CF (Compact Flash) memory card
Data will automatically backfill via FTP after a failed network recovers
Low operation cost
System can run standalone without any operator interaction by FIFO’ing stored data on local CF memory card
Large CF card will store data for a long period without operator intervention
DAQMASTER is smart I/O because it is capable of storing large quantities of data locally. It can also be configured with multiple logging rates, so points that need to be sampled and stored faster can be stored without storing the other points that can be logged more slowly, thereby conserving local memory.
In the event of a network failure DAQMASTER will hold all data and send it after the network is back online.

8. 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.

11. AGA – American Gas Association –
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.

12. 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
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
