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

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
