2 Basic Features Overview DAQMASTER “MW100”Basic Features –FM Approved Class I Div 2Gas Flow Computer with AGA3/AGA8Scalable / Distributed Universal I/OSecure Redundant DataNetwork CapableEasy to ConfigureI/O with High Accuracy, Stability & IsolationBuilt in web server
3 Scalable / Distributed Universal I/O Easily ExpandableBuild 10 to 1000’s of point I/O systemsStart small and expand in the futureReduce wiring and installation costsLocate I/O in any locationAdd I/O to new or existing DCS or PLC without moving existing wiringCost effectiveReduce Spare Parts by stocking common universal I/O modulesVery reliable hardware reduces maintenance costsCalibration 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 cardData will automatically backfill via FTP after a failed network recoversLow operation costSystem can run standalone without any operator interaction by FIFO’ing stored data on local CF memory cardLarge CF card will store data for a long period without operator interventionDAQMASTER 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.DataviaFTP
5 Network Capable Easy integration to existing systems Add I/O to an existing DCS without purchasing expensive I/O cards and DCS tagsAdd modern advanced communication capabilities to your existing PLC or DCS without complex engineering and integration costsSafe guard critical data by storing data locallyExamples:A-B SLC500, PLC5A-B ControlLogixBailey Infi90WestinghouseDeltaVYokogawa CSFoxboro IASeimens S7 PLCDCSFieldControlStationDAQMASTER had serial and Ethernet ports and ModbusRTU and TCP protocol allowing quick and easy connectiion to exiting systems.

7 Easy to Configure Dedicated PC is NOT required Everyone with internet access can view data without special softwareNo annual software license costsView trend, digital & alarm process data and log historical data in minutesEliminate expensive configuration and integration costsBuild control applications without hiring an integratorControl 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 webserverConfigureView Real-time Data
8 I/O with High Accuracy, Stability & Isolation Low operation costOne module can handle any application by measuring any signal from +20/-20mV to +100/-100 V, plus DI contact or Level InputsCalibration is held in each module and terminal blocks can be removedDAQMASTER will withstand accidental over voltage situation with 3700 VRMS (for 1 minute) and 600 VRMS/VDC continuous isolationRemove module without breaking 4-20mA loops. Take the module to the shop for calibration.

11 AGA – American Gas Association – Gas Flow TerminologyAGA – American Gas Association –Industry research and marketing body that promotes standardsFlow ComputerReceives inputs from sensors and applies AGA calculations to record corrected flow rates and energy densityCommon flow sensorsOrifice PlateVenturi-tubeV-ConeTurbine meterCompressibilitygas 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 MW100AGA Gas Flow Computer Features –Supports AGA 3 and AGA 8 methodsOne MW has (10) gas flow computation sets!Currently supports orifice and venturi sensor typesAGA 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 SensorsDensity input is external input or fixed value.AGA 7corrected gas flow in conjunction with Turbine Meters, requires external input for density or fixed value.NX-19Older, 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 8Complex compressibility and density calculationsUses table look-ups and iterative sequencesCompensates 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 SCFHDetail CharacterizationInput complete breakdown by Mole % of gas compositionGross Characterization Method 1Input specific gravity, %CO2, and Heating Value (BTU/FT3)Gross Characterization Method 2Input Specific Gravity, %CO2 , and %N2MW100 Supports all three characterization types
