SAGE METERING INC THERMAL MASS FLOW METERS FOR

SAGE METERING, INC. THERMAL MASS FLOW METERS FOR MEASURING GAS FLOW

HISTORY OF SAGE METERING u u Founded in Sept 2002 by Managers from other Thermal Mass Flow Meter companies Sage Metering has been an Industry leader in high performance Thermal Mass Flow Meters for Gas Flow, and has pioneered numerous innovations, including introducing a Digital method of driving the sensor (versus the traditional drift-prone Wheatstone Bridge)

IN-SITU CALIBRATION CHECK u u We are the only Thermal Mass Flow Meter Manufacturer that provides an "In-Situ Calibration Check" that assures that the Flow Meter still retains the original NIST Traceable Calibration. This simple 3 -step check is conducted at a "No-Flow" (0 SCFM) condition This customer check, verifies the Flow Meter's accuracy, and also confirms that the sensor is clean, and the Meter hasn't drifted or shifted

MARKET OVERVIEW u u u Sage provides high quality In-Line and Insertion Thermal Mass Flow Meters for a wide variety of Industrial, Commercial, and Environmental monitoring applications For the Environment, Sage is a well respected supplier of Flow Meters for Carbon Credit verification for Greenhouse Gas reduction For Energy related applications, the Sage NIST Traceable Thermal Mass Flow Meters have helped many companies increase productivity and efficiencies, while reducing energy costs

SAGE TECHNICAL PRESENTATIONS

WHAT IS A THERMAL MFM?

WHAT IS A THERMAL MASS FLOW METER? u It is a Meter that directly measures the Gas Mass Flow based on the principle of conductive and convective heat transfer

WHAT DO THE SENSORS CONSIST OF? u u The sensors are RTDs, which are Resistance Temperature Detectors They consist of highly stable reference-grade platinum windings clad in 316 SS One of the RTDs is self-heated by the circuitry and serves as the Flow Sensor The other RTD acts as a Reference Sensor. Essentially it is used for temperature compensation

ARE THE SENSORS RUGGED? u. The RTDs are clad in a protective 316 SS sheath for Industrial Environments

u The HOW DOES IT WORK? Sage proprietary sensor drive circuitry maintains a constant overheat, Δt, between the Flow Sensor and the Reference Sensor u As gas flows by the heated sensor (Flow Sensor), the molecules of flowing gas carry heat away from this Sensor, and the Sensor cools down as it loses energy Continued

HOW DOES IT WORK? - Continued u The circuit will automatically (within 1 second) replace this lost energy by heating up the Flow Sensor so the overheat temperature is restored u The current required to maintain this overheat represents the Mass Flow signal

ARE THEIR ANY QUESTIONS ABOUT THE TECHNOLOGY?

WHY THERMAL MFMs over OTHER TECHNOLOGIES?

WHY THERMAL? u DIRECT MASS FLOW – No need for separate T or P transmitters u RANGEABILITY AND SENSITIVITY – Turndown of 100 to 1 – Resolution as much as 1000 to 1 (for Sage) – Sage can even detect 5 SFPM (e. g. , 1 SCFM in 6” pipe) u LOW PRESSURE DROP – Will not impede the Flow or waste energy u NO MOVING PARTS – Eliminates costly bearing replacements, and prevents undetected accuracy shifts u EASE OF INSTALLATION – Insertion Style for pipes 1” and up

ADDITIONAL BENEFITS (Pressure Independence) 15 Data Points at 110 psig (BP), than same output, even at 0 psig (No Back Pressure)

THERMAL MFM ADVANTAGES (OVER OTHER SPECIFIC TECHNOLOGIES) u Temperature and Pressure measurement needed on Vortex, Turbine, Positive Displacement, Orifice, & Pitot Tubes to obtain Mass Flow u Coriolis is expensive and has large head loss u All above have limited turn-down (poor low end sensitivity) and substantial pressure drop u Turbine and Positive Displacement have moving parts (may need frequent maintenance) u Insertion Style meters not available on above technologies (except Pitot Tube and some Vortex)

WHY SAGE THERMAL MASS FLOW METERS over OTHER TMFM COMPETITORS?

IN-SITU CALIBRATION CHECK & DEMO – 3 EASY STEPS Loosen, Lift, Look

IN-SITU CALIBRATION CAPABILITY u All Sage Thermal Mass Flow Meters feature the ability for the customer to verify the meter’s accuracy, as long as a “No Flow” (0 SCFM) condition can be created – This is totally unique to Sage – For years, our Thermal Competitors have required expensive annual factory recalibrations u With the Insertion Style Flow Meter, and an SVA 05 Isolation Valve Assembly mounting accessory, creating a “No Flow” condition is easy – This simple 3 -Step procedure can be done In-Situ and only takes a few minutes – It assures that the meter still retains the original NIST Calibration, and verifies that the meter hasn’t drifted or shifted, and confirms that the sensor is clean

IN-SITU CALIBRATION CHECK FOR SAGE INSERTION THERMAL MFMs 3 -Easy Steps

IN-SITU CALIBRATION CHECK FOR SAGE Step 1 – “Loosen”

IN-SITU CALIBRATION CHECK FOR SAGE Step 2 – “Lift”

IN-SITU CALIBRATION CHECK FOR SAGE Step 3 – “Look”

IN-SITU CALIBRATION EXPLANATION u The reason Sage can perform the In-Situ Calibration Check, is due to the Meter’s extraordinary reproducibility, even at a “No Flow” (0 SCFM) condition u This reproducibility is a direct result of having developed a Digital method of driving the sensors vs the drift-prone “Wheatstone Bridge” u Essentially, the customer can recreate an identical data point to that taken at Sage, at the one condition they can accurately reproduce – “No Flow” (0 SCFM)

SAGE ZEROING CHAMBER (USED TO GENERATE A “NO FLOW” CONDITION)

IN-SITU CALIBRATION mw COMPARISON u The customer simply compares the observed milliwatts (mw) on the Prime display to the Factory’s original data point (noted on the Flow Meter’s Certificate of Conformance or the Meter’s tag). In fact, since the Flow Meter’s raw calibration data is linearized with a 5 th order polynomial, that is stored digitally, any reproducible data point is sufficient to verify that the original data is intact, but only a “No Flow” (0 SCFM) data point can be truly generated by a customer in the field
