DAQMASTER FEATURES AND BENEFITS
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
DAQMASTER FEATURES AND BENEFITS
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
DAQMASTER FEATURES AND BENEFITS
Secure Redundant Data
No lost data Measured data is stored
in 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 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 FEATURES AND BENEFITS
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:

DAQMASTER FEATURES AND BENEFITS
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

DAQMASTER FEATURES AND BENEFITS
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.
DAQMASTER FEATURES AND BENEFITS
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
DAQMASTER FEATURES AND BENEFITS
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
DAQMASTER FEATURES AND BENEFITS
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
